Aerotowing is now becoming a popular part of the modelling scene. When it was first tried some 25+ years ago the tugs and gliders were relatively small and importantly, there was no 7kg/400ft height restriction.
If you go to an aerotow event these days you’ll likely find tugs with 150cc engines and half scale gliders approaching 30kgs. With the huge increase in size it was inevitable that the authorities would take a keener interest in matters.
Older modellers will recall the furore that erupted following the alleged near miss between a DC10 landing at Gatwick and a model aircraft some years ago. As you might imagine the national press had a field day describing the event as “toy aeroplane almost crashes in to huge jet with 200+passengers”. With headlines like these the authorities had to act. Initially, the proposals were draconian, but fortunately with the good offices of the BMFA and some sensible folk in the CAA the proposals were amended to something more acceptable, but the legacy of that event is that powered aircraft weighing more than 7kgs can’t fly more than 400ft above the ground without special permission. I recall this incident deliberately, because it shows just how careful we have to be when we are flying models. Any repetition of this sort of event and we as modellers could be grounded!.
So that’s the serious bit, back to the title; how do we organise an aerotow event?
If you check the relevant legislation- Air Navigation Order(ANO) , CAP 658, and the BMFA handbook, you’ll find that the rules state that outside Controlled Airspace (CAS) powered models above 7kgs are limited to 400ft above the ground. Note the regulations only refer to powered aircraft, not pure gliders, so even our half scale monsters are theoretically excluded and can fly above 400ft without special permission, but they are of course still subject to the other parts of the ANO, namely Articles 73 and 74.
If you want to fly in CAS:
If you want to fly in uncontrolled airspace:
You then ideally fax that off to the CAA, however they do accept emails using email@example.com. Your application will go to the Safety Regulation Group (SRG) in the CAA and remember they are very busy folk with a whole host of other things to do connected with aviation, so the more notice you can give the better, ideally at least 28days.
If your application is successful the Exemption will fall from your letterbox some days later. It’s an official document stating such details as the max. height, max range, min. distances from houses, industrial units, etc. Also quotes from the ANO and BMFA/LMA handbooks. It also gives the name of the organiser - you! In addition, it bestows on the organiser responsibility for ensuring that the event is run in accordance with the conditions of the Exemption.
So it’s up to you that the event is run as safely as possible.
To Contact the CAA :-
Tel 01293 573525/Fax 01293 573973 OR emails- firstname.lastname@example.org.
Once the exemption is granted you must inform the Airspace Utilisation Section (AUS). This is the part of the CAA which transmits the details of your event to the full size community, flying clubs,etc. It goes out in the form of a Notam (short for notices to airmen) and provides full size pilots with details of your aerotow, giving location, time, height etc.
The AUS requires the same information as that which you sent to the CAA, i.e., location, times, height, number of models approximately, organiser and contact numbers. This part of the application should be emailed to AUSOps@caa.co.uk
A point worth mentioning here is that even though a notam has been raised for your event, it doesn’t mean that the airspace you have defined for your aerotow is prohibited to full size aircraft. It simply is a navigation warning for full size pilots and in their own interests is best avoided, but if you see a full size aircraft encroaching in to the aerotow airspace and you suspect it’s below the maximum height you’ve been notified of, you must do everything possible to maximise separation.
To Contact the AUS :-
Tel 0207 453 6599 OR email- AUSOps@caa.co.uk
The final step is to inform the Civil Aviation Notification Procedures (CANP). This branch is responsible for providing the military notice of your intended event and requires the same information as the AUS.
To Contact the CNAP :-

That’s all there is to it. On the day it’s your responsibility to make sure everything goes smoothly and safely, but the current aerotow following are all very experienced modellers, they know what it’s all about and I find it’s a pleasure and a privilege to fly in their company. It’s a wonderful way to spend a weekend.
Have fun and fly safely.
