FEDERAL AVIATION ADMINISTRATION
1. Purpose
This advisory outlines safety standards for
operations of model aircraft. We
encourage voluntary compliance with
these standards.
2. Background
Attention has been drawn to the increase
in model aircraft operation. There is a
need for added caution when operating
free flight and radio controlled craft in
order to avoid creating a noise nuisance
or a potential hazard to full-scale aircraft
and persons and/or property on the
surface.
3. Operating Standards
Modelers generally are concerned with
safety and exercise good judgment when
flying model aircraft. However, in the
interest of safer skies, we encourage
operators of radio controlled and free
flight models to comply with the following
standards:
a. Exercise vigilance in locating full-
scale aircraft (get help if possible) so
as not to create a collision hazard.
b. Select an operating site at sufficient
distance from populated areas so you
do not create a noise problem or a
potential hazard.
c. Do not fly higher than 400 feet
above the surface.
d. Always operate more than three
miles from the boundary of an airport
unless you are given permission to be
closer by the appropriate air traffic
control facility in the case of an
airport for which a control zone has
been designated or by the airport
manager in the case of other airports.
e. Do not hesitate to ask for
assistance in complying with these
guidelines at the airport traffic control
tower or air route traffic control
center nearest the site of your
proposed operation.

DAILY FLIGHT CHECKS
1. Check the battery voltage on both the
transmitter and the receiver battery
packs. Do not fly below 9.0V on the
transmitter or below 4.7V on the
receiver. To do so can crash your aircraft.
Note: When you check these batteries,
ensure that you have the polarities
correct on your expanded scale
voltmeter.
2. Check all hardware (linkages, screws,
nuts, and bolts) prior to each day's flight.
Be sure that binding does not occur and
that all parts are is properly secured.
3. Ensure that all surfaces are moving in
the proper manner.
4. Perform a ground range check before
each day's flying session. The range
check should be as follows:
• Do not extend the transmitter antenna at
this time. Turn the transmitter "on."
• Turn the model "on."
• Slowly walk away from the model while
moving the control surfaces. The aircraft
should function properly at a distance of
60-75 feet.
5. Prior to starting your aircraft, turn off
your transmitter, then turn it back on. Do
this each time you start your aircraft. If
any critical switches are on without your
knowledge, the transmitter alarm will
warn you at this time.
6. Check that all trim levers are in the
proper location.
7. All servo pigtails and switch harness
plugs should be secured in the receiver.
Make sure that the switch harness moves
freely in both directions.
