General Notes
Radio controlled models are a great source of pleasure.
Unfortunately, they can also pose a potential hazard if not
operated and maintained properly.
It is imperative to install your radio control system correctly.
Additionally, your level of piloting competency must be
high enough to ensure that you are able to control your
aircraft under all conditions. If you are a newcomer to radio
controlled flying, please seek help from an experienced pilot
or your local hobby store.

Federal Aviation Administration
Purpose
This advisory outlines safety standards for operations of
model aircraft. We encourage voluntary compliance
with these standards.
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.
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.

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 properly secured.
3. Ensurethatallsurfacesaremovingintheproper

4. Perform a ground range check before each day’s flying
session.
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.
