Making Changes To Your System May Change Your OSC

We are suggesting some basic considerations for those operators that are making changes to / modifying their PFCO specified drone aircraft systems.

No matter why you are changing the aircraft system or payload – you should always reconsider the validity of your Operating Safety Case or Operations Manual and your associated Permission For Commercial Operations (PFCO).

When you change the system, and importantly if you are adding a non aircraft OEM sub system; you should consider the implications of the change on a range of factors:

– Your original safety case presented to obtain your Permission For Commercial Operation (PFCO).
– Your aircraft system manufacturers warranty.
– Your insurance cover.
– Your current hazard assessments.
– The impact on the weight and balance of the aircraft.
– The impact on the aircraft system maintenance.
– The impact on the aircraft system reliability and life.
– The impact on operating procedures.
– The impact on human factors.
– The impact on crew training and experience.

Any modifications require some level of analysis and development of some supporting evidence to ensure that the Operating Safety Case (OSC) support the safety claims. Significant changes must be reported to the CAA to ensure that your PFCO remains valid or is amended.

We recommend:

– Assess the impacts of any change to an aircraft system even if you considered it to be safer.
– Gain experience of changes with planned training and trials flights.
– Prove the system in a controlled environment and to the limits of its intended operation.
– Generate evidence to underpin your safety claims.
– Document changed claims and evidence.
– Resubmit changes to CAA if significant.

Our Assistance:

We are assisting customers to analyse their system modifications and/or operational changes and successfully analysing and developing the additional OSC evidence for non standard systems and systems of systems, from different manufacturers.

If you are planning to make changes to your system, for example fitting modifications to increase performance or safety using a third party systems or spares then why not get in touch to get a point in the right direction.

Modification Example: 3rd Party Tether Sub System and Power Supply:

For example – are you considering adding a drone tether that is not provided by the aircraft OEM and is not on your current OSC ?

If you have already followed a logical approach to documenting the impact then that is great. If not, have you thought of the factors above? Has the modification affected your current Operating Safety Case (OSC), Permission For Commercial Operation (PFCO), Warranty or insurance ?

Modification Example: 3rd Party Aircraft Environmental Protection Measures:

For example – are you considering having a drone environmentally protected which is not provided by the aircraft OEM and is not on your current OSC ?

If you have already followed a logical approach to documenting the impact then that is great. If not, have you thought of the factors above? Has the modification affected your current Operating Safety Case (OSC), Permission For Commercial Operation (PFCO), Warranty or insurance ?

Our initial engagement is always free. We are always happy to help you should you require it. We could help you understand how ta modification may affect your safety case and the list of implications and considerations listed above.

A Visit By BBC Xray

A few weeks ago we had a fun packed visit from the BBC Xray team who were filming for their Photography Special.

We helped Omar Hamdi find out about all the dos and don’ts of flying a drone safely.  This included our experience session which saw him having his first few experience flights.

Here are a few screen captures from the BBC visit to out office and flying site.

See our very short debut on the following link (at 14:45 minutes in) while it is still view-able on BBC iPlayer.

Whether you are a professional or hobby flyer you can book a professional and friendly drone support session. We cater for all levels of experience from zero to experienced.

Ignorance Is Not An Excuse – Check

We Assist Hobby And Commercial Drone Operators To Fly Safe And Legally.

A local group page on social media that we have on our feed recently added a post form a drone pilot, proud of their imagery captured of the USS George HW Bush.

When you see footage like this it makes you start to understand why the UK CAA, Department For Transport and EASA are proposing new measures to cover hobby and commercial drone operators.

There are many flying restrictions in this area of the UK and there is a No Fly Zone which is a Temporary Restriction on flying at this specific site. The restriction is from the surface to 2500 feet AMSL and valid until 17 Aug 17 @ 11:30. Police and Air Ambulance helicopters are exempt.

We regularly witness images and videos posted online from drone flights that make us wince.

This time it was not only us the flight also caught the eye of  a well respected drone news feed. Their article is linked below and our thoughts below that.

Our thoughts –

If you’re flying a drone for either hobby or commercial use –  ignorance is not an excuse. Never assume you can fly – always check! Just because you see another drone flyer do it – it doesn’t mean it’s OK.

The onus is on the flyer to find out what the rules are for what they are flying, and where they are operating. With modern drones operating more sophisticated control systems and  their high definition payloads, the pilot needs to ensure they are flying safely and legally.  There are many facets to hobby and commercial drone operation such as safety, privacy and security.

The rules for safe flight of drones in UK have been available for many years, but you needed to work at finding them especially if you were not a commercial operator and so had not been made to learn about CAP 393 and CAP 722. More and more information is now being made available to drone flyers from many media sources including the myriad of social media platforms.

We use a number of these applications as well as UK CAA air navigation charts and NATS services.

As a result of the steadily growing number of reported incidents – in recent news, the UK Department For Transport (DfT) has published the findings of its public consultation on drones –


Examples of content of the document:

“Owners of drones weighing 250 grams and over will in future have to register details of their drones to improve accountability and encourage owners to act responsibly.”

“In addition, a new drone safety awareness test means owners will have to prove that they understand UK safety, security and privacy regulations.”

These measures come after a consultation looking at ways to make drone use safer while maximising their potential.

There is also an EASA proposal published looking at a range of measures to ensure safe operation of drones more about that here –

Our Support Is Available:

There is a range of free online assistance and a growing range of software applications to assist hobby and commercial pilots to fly legally. There is no excuse these days and if you are in any doubt – ask!

We love to talk drones – so you can contact us here or use our web-chat facility here IT’S FREE !!

UK CAA – SRG1320 Application Issues

If You Are Applying For A UK CAA PFCO SeeBelow:

As a CAA UK Restricted Nation Qualified Entity (R-NQE) we receive information by email from the UK CAA regarding drone operation and the Permission For Commercial Operation (PFCO) applications process, to help the process move smoothly. Today received one such email. The email contained current issues that the CAA are experiencing with regards applications for PFCO.  Applications that have anomalies cost the CAA in resource time and may delay your application, while the operator ensures that issues are rectified. To assist operators about to apply for a PFCO, we have extracted the core content of the email to us:

“We are currently experiencing problems with applications regarding legal entity names not being identical on all aspects of the UAV applications received at the CAA. I have summarised the issues below:

1. The applicant must only fill out section 2 or section 2a of SRG1320. Section 2 if the applicant is a sole trader or partnership and Section 2a if a registered company (as referenced on the application form).

2. The Company or Sole trader name must be identical to the Insurance Cover. E.g. If ‘ABC Limited’ is on the application form, this needs to be the exact name on the Insurance Policy received.

3. Furthermore, the Limited Company name on the Application Form and the Insurance Policy, must match what is stated on Companies House. Additionally, a sole trader cannot trade as a Limited company. We will put the application on hold and ask for all three items to be identical.

We are receiving many Applications where the applicant has filled out the Sole trader section and the Limited Company section. Also, the applicant has different names on each part of the Application. E.g. ‘ABC Limited’ on the SRG1320, ‘DEG Ltd trading as ABC’ on Companies House, and just the pilot name on the insurance Policy.  

We have been instructed by the Authorities Legal and Financial departments to enhance this part of our assessment process for the issue of a permission/approval. Therefore, you may receive a few applications returned to you ‘on hold’, as well as applicants who have applied in their own right to the CAA.”

Our summary:

♦ Check that you complete the correct section of the SRG1320 for your specific organisation type.

♦ Ensure that the organisation name is accurately completed in all areas of your application – SRG1320 and the Insurance cover document.

♦ Ensure that if operating under a Limited Company that your company name used in Section 2a of the SRG1320 and Insurance documents accurately match the name on Companies House.

If you are not sure, then ask. Either through the CAA standard enquiries email  or, get in touch with us and we will point you in the right direction or the direction in which to find the answer.

Drone Hobby Pilots – Our Advice


The Rules

If you are flying a Drone for sporting and recreational purposes, including recreational (non-commercial) aerial photography and videography, they are considered to be model aircraft; the law makes no specific distinction on types of aircraft, other than weight limits, and all model aircraft pilots should read and understand the guidance contained in the CAA publications:

CAP 393 – Air Navigation: The Order and Regulations – CAA Link

CAP 658 – Model Aircraft: A Guide to Safe Flying – CAA Link

CAP 722 – Unmanned Aircraft System Operations in UK Airspace – Guidance – Auto stabilisation, flight automation and with video payloads. CAA Link

The latest version of these documents are available at the links above in electronic format and is where you may also register for e-mail notification of amendments. Before flying a drone or any radio controlled aircraft, you should make sure you’ve read the latest legal requirements.

In Summary

These rules applied with a little common sense will ensure you are complying with the relevant legal requirements.

The basic aims of the main Air Navigation Order provisions is to prevent members of the public and full size aviation being endangered, and these provisions also help to limit the potential for causing nuisance and for invading privacy.

The basics are summarised in The CAA Drone Code. The Drone Code:

♦ Always keep your drone in sight – This means you can see and avoid other things while flying

♦ Stay below 400ft – This reduces the likelihood of a conflict with manned aircraft

♦ Every time you fly, follow the manufacturer’s instructions – Keep your drone and the people around you safe

♦ Keep the right distance from people and property – 50m from people and property, 150m from crowds & BU areas

♦ You are responsible for each flight – Failure to fly responsibly could result in criminal prosecution

♦ Stay well away from aircraft, airports and airfields – It is a criminal offence to endanger safety of an a/c: could = prison for 5 years

The latest copy of the Drone Code can be found  – here

Data Protection and CCTV Rules

You need to be aware that the collection of images of identifiable individuals, even inadvertently, when using a camera mounted on a drone will be subject to the Data Protection Act. This act contains requirements concerning the collection, storage and use of such images. Drone operators should ensure they are complying with any applicable requirements or exemptions. Further information about the Data Protection Act can be obtained from the Information Commissioners Office website:

Insurance For Hobby Flyers

Consider insurance; even as a hobby flyer as you may be liable for 3rd party damage and personal injury claims should you have an accident and damage is caused. This mandatory for commercial operation.

First Person View Pilots

N.B. The CAA issues an exemption to Article 94 (3) for First Person View (FPV) operation. See here for details.

Hobby Flying Locations

If intending to fly on private land, then the permission of the landowner should be sought, if flying on public land, such as a park or open access site then you must ensure that there are no bylaws in place specifically prohibiting or restricting model flying.

The other main consideration is the overall suitability of the location for the activity, and that all flying can take place in compliance with the primary “endangering” provisions of the ANO and also in accordance with the distances mandated.

There are a number of emerging applications to assist with safe Drone flying. These will identify your location and provide yo with an indication of the flight hazards including classification of airspace. With these you may also have a facility to indicate to other application users that you are flying in that specific location. Like all of these tools, you need to ensure that you keep them up to date with the latest information.


Please do not assume that just because one pilot is doing it, that it is acceptable, safe and legal. There are many British Model Flying organisations and a growing number of UK CAA National Qualified entities that would be able to provide you with the information you require.

At AJSSL we are always happy to provide independent advice and guidance to recreational pilots to ensure that they enjoy their hobby whilst flying safe and legal. We have a webchat facility that you are welcome to use for queries.

UK CAA – updated charges for PFCO applications

We’ve been working with customers who are going through the procedure for gaining a licence to fly commercially from the UK CAA  – a Permission For Commercial Operation (PFCO) and thought a reminder about the April 2017 changes to the CAA fees.

If you’re in the process of applying, or thinking about applying to operate commercially, you may not be aware that the cost of the application rose on 1st April 2017.  Usually, these charges are outside of any course fees that you will pay for ground school and examination etc.

On the 1st April 2017, the UK CAA brought into effect their new charges for General Aviation.

The fee for an initial application for a sub 20kg UAS, for a standard PFCO permission is now £173.

Application Type

Initial Charge

Renewal Charge

SUA (20kg mass or less without fuel) – ‘Standard’ permission or exemption

(See Note 3)



SUA (20 kg mass or less without fuel) – ‘Non Standard’ permission or exemption

(See Note 4)



UAS >20kg to 150 kg (mass without fuel) – permission or exemption


(See Note 5)


UAS > 150 kg (mass without fuel) – permission or exemption


(See Note 6)


Special UAS projects

(See Note 8)


(See Note 7)


Issue of a duplicate permission/exemption



Notes referred to in the table above:

3. ‘Standard Permission’ means any simple approval to perform commercial operations in accordance with ANO 2016 article 94(5) and/or a permission to operate an SUA of 7kg or less within a congested area in accordance with ANO 2016 article 95(2)(a).

4. ‘Non Standard’ permission/exemption means any approval which involves the assessment of an Operating Safety Case.

5. Plus charges in excess of 7 work hours at £173 per hour up to a maximum of £10,000 per year or part of a year.

6. Plus charges in excess of 7 work hours at £173 per hour up to a maximum of £20,000 per year or part of a year.

7. Plus charges in excess of 7 work hours at £173 per hour up to a maximum of £100,000 per year or part of a year.

8. A Special UAS Project involves consideration by the CAA to develop the existing framework under which the current regulation of UAS is undertaken. Plus charges in excess of 7 hours would be charged at £173 per hour up to a maximum of £100,000 per year or part of the year in which the CAA investigations take place apply.

9. All excess hours would be invoiced monthly in arrears by the CAA to the applicant and payable on demand.

10. Renewal of a permission/exemption assumes that there are no changes involved. Renewals which involve changes in either documentation or operating requirements will be charged as Variations

11. Reinstigation of expired permissions will be charged at the full rate as if they were new permissions.

UK CAA Commercial Drone Operator List

The latest CAA list of UK Commercial Drone Operators came out on 17 April 2017 – Version 25

It is published in a Civil Aviation Publication (CAP) 1361, on the UK CAA website here.

As fast as the list grows, there are an ever increasing number of “Drone List” facilitators. These usually charge for operators to be on their list, often with levels of membership and facilitation and therefore influences the operators promoted.

CAP 1361: Small Unmanned Aircraft (SUA) operators holding a valid CAA permission is the authoritative list of operators holding a UK CAA Permission For Commercial Operation. This is all of the operators that have been successful and have currently valid approvals for the categories shown. We see operators “drop off” and reappear on the list which over the years we attribute to a delay or timing issue in the list collation and the renewal process for the operator.

From 2427 operators listed in the last Feb 2017 edition of the list, there are now 2629 operators.  The list published on the UK CAA website can be used in a number of ways. Here are 2 suggestions for finding a safe and legal commercial drone operator in UK:

As a check list: It is easy to use your favourite search engine to find operators and then search the official list of names in the pdf document to confirm that the company you wish to use are currently on the list.

Browse the list: If you are starting with the list, unfortunately there are no links to the company webpages, but typing the name from the list into a search engine will provide you the contact information.

If you have queries or need assistance with either finding a Drone operator in UK or becoming a Drone operator – we are always happy to promote safe and legal Drone operation for Hobby and Commercial use; please get in touch – contact or use the web-chat facility on this website.

Please note; we pride ourselves on being independent, so we will not promote any one Drone system, operator or training service over another.

Drone Pilot Assessment – The Criteria

What’s in a UK Commercial Drone Pilot Assessment?

There are a growing number of National Qualified Entities (NQE) and Restricted Category NQEs. All operate to a UK CAA minimum criteria standard set out in CAP 722.

We see and receive a number of queries about what to expect on a Drone Pilot Assessment. Our potential pilots that approach us for assessments are fully briefed in advance, but some are from pilots entering a short intense course with another NQE, often they wish to ensure they turn up prepared. Not all pilots require a ground school. If you are unsure of your options, then please get in touch and we will provide independent advice as to the evidence you should expect to provide to the UK CAA.

No matter how your chosen R-NQE/NQE deliver the service, the minimum UK CAA criteria in CAP 722 for a Commercial Drone Pilots Practical Assessment is:

Ensure that their students are able to satisfactorily demonstrate at least the following skills during the practical flight assessment:

§ Pre-flight actions including:

§ Mission planning, airspace considerations and site risk-assessment.

§ Aircraft pre-flight inspection and set-up (including flight controller modes and power-source hazards).

§ Knowledge of the basic actions to be taken in the event of an aircraft emergency or if a mid-air collision hazard arises during the flight.

§ In-flight procedures including:

§ Maintaining an effective look-out and keeping the aircraft within Visual Line of Sight (VLOS) at all times.

§ Performing accurate and controlled flight manoeuvres at representative heights and distances (including flight in ‘Atti’ (non-GPS assisted) mode or equivalent where fitted).

§ Real-time monitoring of aircraft status and endurance limitations.

§ Demonstration of the ‘return-to-home’ function following deliberate control-link transmission failure. Fixed-wing aircraft may demonstrate an equivalent procedure that results in a suitable automated, low-impact descent and landing.

§ Post flight actions including:

§ Shutting down/making-safe the aircraft.

§ Post-flight inspection and recording of any relevant data relating to aircraft general condition, aircraft systems, aircraft components and power-sources, controller functionality and crew health and fatigue.


Our process is explained on our Drone Pilot Assessments page of this website.
