Instruction Manual

•   Officially designated AMA Air Show Teams (AST) are authorized to use devices and practices as defined within 

the Team AMA Program Document. (AMA Document #718.)

(j)  Not operate a turbine-powered aircraft, unless in compliance with the AMA turbine regulations. (AMA Document 

#510-A.)

3.   Model aircraft will not be flown in AMA sanctioned events, air shows or model demonstrations unless:

(a) The aircraft, control system and pilot skills have successfully demonstrated all maneuvers intended or anticipated 

prior to the specific event.

(b) An inexperienced pilot is assisted by an experienced pilot.

4.  When and where required by rule, helmets must be properly worn and fastened. They must be OSHA, DOT, 

ANSI, SNELL or NOCSAE approved or comply with comparable standards.

B.  RADIO CONTROL (RC)

1.  All pilots shall avoid flying directly over unprotected people, vessels, vehicles or structures and shall avoid 

endangerment of life and property of others.

2.  A successful radio equipment ground-range check in accordance with manufacturer’s recommendations will be 

completed before the first flight of a new or repaired model aircraft.

3.  At all flying sites a safety line(s) must be established in front of which all flying takes place. (AMA Document 

#706.)

(a) Only personnel associated with flying the model aircraft are allowed at or in front of the safety line.

(b) At air shows or demonstrations, a straight safety line must be established.

(c) An area away from the safety line must be maintained for spectators.

(d) Intentional flying behind the safety line is prohibited.

4. RC model aircraft must use the radio-control frequencies currently allowed by the Federal Communications 

Commission (FCC). Only individuals properly licensed by the FCC are authorized to operate equipment on 

Amateur Band frequencies.

5. RC model aircraft will not knowingly operate within three (3) miles of any pre-existing flying site without a 

frequency-management agreement. (AMA Documents #922 and #923.)

6.  With the exception of events flown under official AMA Competition Regulations, excluding takeoff and landing, no 

powered model may be flown outdoors closer than 25 feet to any individual, except for the pilot and the pilot's 

helper(s) located at the flightline.

7.  Under no circumstances may a pilot or other person touch an outdoor model aircraft in flight while it is still under 

power, except to divert it from striking an individual.

8. RC night flying requires a lighting system providing the pilot with a clear view of the model’s attitude and 

orientation at all times. Hand-held illumination systems are inadequate for night flying operations.

9.  The pilot of an RC model aircraft shall:

(a) Maintain control during the entire flight, maintaining visual contact without enhancement other than by corrective 

lenses prescribed for the pilot.

(b) Fly using the assistance of a camera or First-Person View (FPV) only in accordance with the procedures outlined 

in AMA Document #550.

(c) Fly using the assistance of autopilot or stabilization system only in accordance with the procedures outlined in 

AMA Document #560.

C.  FREE FLIGHT

1.  Must be at least 100 feet downwind of spectators and automobile parking when the model aircraft is launched.

2.  Launch area must be clear of all individuals except mechanics, officials, and other fliers.

3.  An effective device will be used to extinguish any fuse on the model aircraft after the fuse has completed its 

function.

D.  CONTROL LINE

1.  The complete control system (including the safety thong where applicable) must have an inspection and pull test 

prior to flying.

2. The pull test will be in accordance with the current Competition Regulations for the applicable model aircraft 

category.

3.  Model aircraft not fitting a specific category shall use those pull-test requirements as indicated for Control Line 

Precision Aerobatics.

4.  The flying area must be clear of all utility wires or poles and a model aircraft will not be flown closer than 50 feet 

to any above-ground electric utility lines.

5.  The flying area must be clear of all nonessential participants and spectators before the engine is started.
