General Flying Field Safety Code

  1. All model flying will be done under and accordance to the official Academy of
    Model Aeronautics National Model Aircraft Safety Code. 
  2. As defined in paragraph four of the above mentioned safety code, a safety line or
    lines must be established. The safety lines will be established as follows:
    • Winch launch sailplane: (contest and/or fun flying), a line perpendicular to
      the winch line starting at the winch and extending approximately 40
      meters or 85 feet both sides of the winch.
    • Electric launch sailplane contests, the CD must establish and clearly mark
      the safety line. For electric launch sailplane fun flying, a consensus of the
      pilots will establish and clearly mark the safety line.  If a winch is setup,
      the winch launch safety line is in effect.
    • Non-sailplane electric flying, a consensus of the pilots will establish and
      clearly mark the safety line.  If a winch is setup, the winch launch safety
      line is in effect and no flight can commence without the approval of the
      "Winch Master" or the CD if it is a contest day.  If it is an electric sailplane
      launch day, then that safety line will be in effect.
    • The frequency clips are to be available to the pilots near the safety line. 
      No pilot will be allowed to turn on a RC radio without the appropriate
      frequency clip in his possession.
  3. A First-aid kit is available for any minor injury or use of the first-aid kit should be
    reported to the CD, club officer or Safety Office, for supply replenishment. 
    Any and all serious injuries must be reported to the park authorities.
  4. Any violation of the above mentioned AMA or the Club Safety codes could result
    in a request to leave the flying field and or lost of the privilege of use of the flying
    field. Any conduct that endangers others is prohibited and may result in
    contacting the park authorities to resolve. 

VISUALIAZTION; with all the pilots in approximately in the same area they should
be able to see that the others are doing.
COMMUNATION; with all the pilots in approximately in the same area they should
be able to broadcast intent or warnings of the actions.
FREQUENCY COMTROL; the frequency clips must be readily available for the
pilots to use and the CD or winch Master must enforce the no clip, no fly rule.

Detailed Flying Field Safety Code




These guidelines are not meant to replace the AMA safety rules (posted on the shed door), but are to be observed and followed in conjunction with them.

You are expected to sign the safety form in the shed each timethat you fly at the Addison Oaks field indicating that you have: read, understand and plan to follow all of the rules and guidelines posted to the best of your ability.


During contest days, the follow items will be rules: 

1.      You cannot fly at the GDSHS field without a current AMA membership.

2.      If you feel you are not capable of following the rules and guidelines, you should not fly.

3.      Unless you are a contestant, you will not fly while the contest in underway, and if you are a contestant, you will not fly other than contest flights.

4.      All flights during a contest will be made with a spotter/timer dedicated to observing conditions that could pose a safety problem. The spotter/timer will advise his/her pilot of a possible course of action to avoid potential problems.
Of course the pilot makes the final choice on the course of action in the case of an emergency/incident with the plane, as the responsibility of safety to others lies in the hands of the person with the transmitter.

5.      Only trained winch operators are to run the winch equipment.



1.      The field layout for each day must contain landing tapes to designate the landing area that the sailplane pilot is expected to use for landings (not a spot landing but a landing area). This is the only way for a non-sailplane pilot to know the control areas he/she is not to fly in or through. The winch area and launch direction is self-evident.

2.      In all cases sailplanes (even electric launched sailplanes not under power) have the right away over powered ships.

3.      If you feel you are learning to fly, and you are someone that needs help, you should not fly unless someone of sufficient flying capability is with you and can take over the transmitter if you become uncomfortable.

4.      You are considered a competent sailplane pilot when you can fly successfully and land in the designated landing area.

5.      Pilots should move away from the winch after launching and avoid standing in the landing area until they are ready to land.

6.      No low flight (under 30ft) or landing in the sod area unless it is designated as the landing area. (The sod patch is the launch area under normal conditions).

  1. The winch operator will not also act as a spotter/timer, one job at a time.
  2. On non-contest days; If the winch is being used and pilots are flying sailplanes, all other pilots flying sport electrics will show field etiquette by;
    1. Ask permission of the sailplane pilots if they can fly at the same time.
    2. If given permission, the electrics pilots will fly in an area that does not jeopardize the launch and landing area for the sailplane pilots (see item 1 of these Guidelines).
    3. The powered plane pilot should never stand in an area that will be used by the sailplane pilot to launch or land.
  3. On days with electric sport and WLS sport flying simultaneously, a spotter should be with the powered plane pilot as well as one with the sailplane pilot to assure that conflict with the sailplanes does not happen.
    1. If at all possible, sailplanes and sport electrics should alternate flying time as the best possible airtime sharing condition.
  4. Electric Launched Sailplanes (ELS) are a special case that bridges sport electrics and pure sailplanes but are to be treated as sailplanes as far as the electric sport flyer is concerned.
  5. ELS’s should launch close to the winch and in the direction that the winch launching is taking place so communications with the WLS pilot about the launch sequence can be easily communicated.
  6. Hand launched sailplanes and hi-start launched sailplanes are special cases and should be flown so as not to be in the launch/landing areas of the WLS’s. The guidelines and field etiquette should be much the same as those for the sport electric.
  7. Whenever launching any sailplane, by winch, electric motor, hand launch or hi-start, the pilot should check to make sure he is the only one launching at that time, and shout out “launching” to alert other pilots and anyone else in the launch area. If more than one type of launching taking place, turns should be taken for launching.
  8. Pilots who are not flying and spectators should keep clear of the launch and landing areas.
  9. Reminder: Also flyers should be current club members (visitors get to fly two days before expected to join the club)
