People first
Flying areas should be arranged so that aircraft do not pass over spectators, participants, vehicles or other occupied areas.
Safety
Safe aeromodelling starts well before launch: with a prepared site, a technically sound aircraft, suitable weather, clear responsibilities and disciplined decisions.
Core principle
These are baseline principles for UAL training, club activity, youth sessions and events. Specific competitions and locations may impose additional official rules, organiser instructions and airspace requirements.
Flying areas should be arranged so that aircraft do not pass over spectators, participants, vehicles or other occupied areas.
Structure, controls, power, radio link and all safety-critical components should be checked before launch.
At organised events, every participant should know who controls the flight order, where the flying boundaries are and which instruction means stop immediately.
Before launch
Even a familiar aircraft deserves a short inspection before every flight. Transport damage, loose hardware, low battery state or an incorrect model configuration can turn a routine launch into an unsafe situation.
Flying site
Define take-off and landing directions, pilot positions, model preparation areas, spectator zones and safe routes between them before activity starts.
If a person, animal or vehicle enters the flying area, pause the launch or change the flight path. Do not assume that bystanders understand model-aircraft hazards.
Operate only where current rules and airspace restrictions allow. Consider temporary restrictions, nearby aerodromes and other aviation activity.
Wind, gusts, precipitation, thunderstorms, fog and poor visibility can quickly exceed the safe operating envelope of the aircraft or pilot. If confident control is not assured, postpone the flight.
Equipment
Use batteries within manufacturer limits. Do not fly damaged, swollen or overheated packs. Charge with appropriate equipment in a place where the process can be supervised.
Keep the propeller arc clear before arming or starting. Secure the aircraft so accidental power cannot move it towards people. Replace damaged propellers and mounts.
Confirm the correct model memory, failsafe settings and reliable control before flight. At busy events, follow the organiser’s frequency and transmitter procedure.
After major repairs, centre-of-gravity changes, power-system changes or control modifications, treat the aircraft as a new configuration and conduct a full technical check.
Youth
Youth sessions must reflect participants’ age, experience and ability to assess risk. Mentors should explain why a procedure is safe, not merely demonstrate it.
UAL events
Set site boundaries, flight order, responsible roles, basic incident procedures and participant communication before the first launch.
Maintain your aircraft, disclose technical issues, follow safety instructions and terminate a flight if safe control can no longer be guaranteed.
After a crash or unsafe event, do not automatically return the aircraft to the air. Identify the cause and inspect safety-critical components first.
Reporting a hazard should help prevent recurrence. The objective is to understand risk and improve procedures, not discourage people from speaking up.
Safety questions
Contact UAL about safety rules, event procedures or a risk you believe should be addressed.
