AMA SAFETY CODE (excerpts)
Read and abide by the following Academy of Model Aeronautics Official Safety Code: GENERAL 1. I will not fly my model aircraft in sanctioned events, air shows, or model flying demonstrations until it has been proven to be airworthy by having been previously successfully flight tested. 2. I will not fly my model aircraft higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give right of way to, and avoid flying in the proximity of full scale aircraft.Where necessary an observer shall be used to supervise flying to avoid having models fly in the proximity of full scale aircraft. 3. Where established, I will abide by the safety rules for the flying site I use, and I will not willfully and deliberately fly my models in a careless, reckless and/or dangerous manner. 7. I will not fly my model unless it is identified with my name and address or AMA number, on or in the model. 9. I will not operate models with pyrotechnics (any device that explodes, burns, or propels a projectile of any kind). RADIO CONTROL 1. I will have completed a successful radio equipment ground check before the first flight of a new or repaired model. 2. I will not fly my model aircraft in the presence of spectators until I become a qualified flier, unless assisted by an experienced helper. 3. I will perform my initial turn after takeoff away from the pit or spectator areas, and I will not thereafter fly over pit or spectator areas, unless beyond my control.
4. I will operate my model using only radio control frequencies currently allowed by the Federal Communications Commission... Since the Giant P-51D Mustang ARF qualifies as
a “giant scale” model and is therefore eligible to
fly in IMAA events, we’ve printed excerpts from
the IMAA Safety Code which follows.
IMAA SAFETY CODE (excerpts)
Definition: For the purpose of the following IMAA Safety Code, the term Giant Scale shall refer to radio controlled model aircraft, either scale or non-scale, which have a wingspan of 80 inches or more for monoplanes and 60 inches or more for multi-winged model aircraft and have a ramp weight (fueled and ready to fly) of 55 lbs. or less. Section 1.0: SAFETY STANDARD 1.1 Adherence to Code: This safety code is to be strictly followed 1.2 The most current AMA Safety Code in effect is to be observed. However, the competition sections of the code may be disregarded. Section 3.0: Safety Check 3.4 Flight Testing: All Giant Scale R/C aircraft are to have been flight tested and flight trimmed with a minimum of six flights before the model is allowed to fly at an IMAA Sanctioned event. 3.5 Proof of Flight: The completing and signing of the Declaration section of the Safety Inspection form by the pilot (or owner) shall document as fact that each aircraft has been successfully flight-tested and proven airworthy prior to an IMAA event.
Section 5.0: EMERGENCY ENGINE SHUT OFF (kill switch) 5.1 All magneto spark ignition engines must have a coil grounding switch on the aircraft to stop the engine. This will also prevent accidental starting of the engine. This switch shall be readily available to both pilot and helper. This switch is to be operated manually and without the use of the radio system. 5.2 Engines with battery power ignition systems must have a switch to turn off the power from the battery pack to disable the engine from firing. This will also prevent accidental starting of the engine. This switch shall be readily available to both pilot and helper. This switch shall be operated manually and without the use of the Radio System. 5.3 There must also be a means to stop the engine from the transmitter. The most common method is to close the carburetor throat completely using throttle trim. However, other methods are acceptable. This requirement applies to all glow/gas ignition engines regardless of size. Section 6.0: RADIO REQUIREMENTS 6.1 All transmitters must be FCC type certified. 6.2 FCC Technician or higher-class license required for 6 meter band operation only. Additional IMAA General Recommendations The following recommendations are included in the
Safety Code not to police such items, but rather to
offer basic suggestions for enhanced safety.
Servos need to be of a rating capable to handle the loads that the control surfaces impose upon the servos. Standard servos are not recommended for control surfaces. Servos should be rated heavy-duty. For flight-critical control functions a minimum of 45 inch/ounces of torque should be considered. This should be considered a minimum for smaller aircraft
