The Chicago Glider Club prefers to trust the individual pilot's judgment in contrast to generating a number of definitive rules. However, the following policies are expected to be followed:


Aerotow Procedures

FAR 91 .309(a)(5) requires that before conducting aerotow operations, the pilots of the towing aircraft and the glider "have agreed upon a general course of action, including takeoff and release signals, airspeed, and emergency procedures for each pilot."

Chicago Glider Club pilots have tacitly agreed to such procedures through Club practices, safety seminars, and discussions with tow pilots and glider pilots, thus not delaying towing while such matters are discussed before each flight.

To ensure compliance with the applicable regulation, and to make sure that everyone is following the same procedures that govern CGC towing operations, whether such operations occur at CGC Field or on retrieve from another location, these procedures are set out below.

Should other procedures be more appropriate, any variance will be agreed upon by both tow pilot and glider pilot prior to commencing such tow, or by radio when airborne. Responsibility for determining the appropriate procedures remains with the pilots involved, based on their review of the relevant circumstances.

  1. The standard signals for ground and on-tow operations arc those listed in the SSA Soaring Flight Manual, and will apply. Each member has reviewed these signals, is familiar with them, and will use them.
  2. The glider pilot is responsible for arranging for a wing runner, if one is to be used, and for briefing the wing runner as necessary for safe operations.
  3. Unless directed otherwise by the glider pilot, the tow pilot will tow the glider until it releases, or until 3,000 feet AGL is reached. Upon reaching 3,000 feet AGL, the tow pilot will level off and wait for the glider pilot to release or for an instruction from the glider pilot. The glider pilot will inform the tow pilot, either by ground signal or radio prior to or after takeoff, of any variance from this procedure that he or she desire(s).
  4. The glider pilot will advise the tow pilot prior to takeoff or by radio if a tow to a specific location or if maneuvering outside the normal high-tow position is intended.
  5. Tow airspeeds will not be less than 60 knots (70 mph) for fiberglass gliders and 55 knots (65) mph) for other gliders.
  6. The glider wing will not be raised until the glider pilot signals ready for takeoff.
  7. The following emergency procedures will apply:
  • ...    In the event of a power failure while the tow plane is on the ground or at an altitude from which an immediate landing on the takeoff runway is possible, both glider pilot and tow pilot will attempt to release, the tow plane pilot will attempt to move to the left side of the runway and the glider pilot to the right side.
  • ...    In the event the tow plane pilot notices something is wrong with the glider, such as the spoilers are open, he/she will advise the glider pilot by radio and continue the tow to at least 2,000 AGL (if possible) while returning to over or near the glider field prior to signaling the glider pilot to release.
  • ...    In the event any other emergency or distracting occurrence arises while in flight that makes aerotow difficult or impossible (such as canopy opening, instrument malfunctions, or the like), the tow pilot will attempt to reach a safe altitude so as to increase the time available to deal with the problem.

Use of Club Sailplanes for Cross-Country Flights


Use of club gliders for cross-country flying by qualified members is strongly encouraged.

For cross country flight, "qualified" means a member must not only be capable of conducting the flight competently, but he must have ensured that he has a capable retrieve crew in place, whether by aerotow or trailer. (See the guidelines below.)

Each pilot is the judge of his/her competence to attempt a given cross-country flight. However, a member should seek counsel of a club instructor who has cross-country experience before attempting his/her first few cross-country flights. Failure to do so would indicate poor judgment.

Please see the Glider Reservation Policy for the details of reserving a glider for cross- country flights.


The board has established these minimal requirements:


If you plan to have an aerotow back from a landing at another airport, you shall arrange to have a willing tow pilot available for the retrieve.

Since an outlanding is possible, you shall:

Reservation of Club Sailplanes

  1. Club gliders are reserved on the board located near the clubhouse door on the south wall of the hanger. The board is marked with time slots for each glider.
  2. Glider reservation is on a "first come-first served" basis. The first member to sign up has their choice of time slots. It is not allowable to reserve multiple time slots (except as allowed by the cross-country policy). After landing from the first flight, any open slots are then available for reservation. Time slots may not be reserved on any previous day, unless the board has approved taking the glider away from our field (to a contest, for example).
  3. A club member may not reserve consecutive time slots on any one glider for local flying. Two individual club members (but not two members of the same family membership) flying a two-place glider may reserve consecutive slots and need not land between slots.
  4. The time period between slots is intended for transfer of the glider to the next user. Each user must have the glider on the runway by the end of their reserved time slot so that the next user can be ready for tow when their time slot begins.
    • a) If the previous user runs into your time slot, you have been wronged. By all means discuss it with him or her, but your time is still up at the end of your time slot.
  5. Quite often, the glider usage is not heavy. Notwithstanding all of the above, you may fly as long as you like, provided that you can determine that no one wants the glider. It is fair to make a radio call and have someone at the clubhouse check for you, but it is your responsibility to be sure that no one is has signed up for the glider you are flying. If you can't verify that no one has signed up for the glider, then you must assume that someone has and land before your time is up.
  6. All of the gliders now have radios and we need to keep the base station active whenever anyone is flying. Likewise the glider radios should be on while you are flying. If you sign up for a time slot while someone else is in the air, it is courteous to contact him or her by radio to let them know that you will be waiting.
  7. The Discus CS, the Duo-Discus and one ASK-21, may he reserved for cross-country flights by writing your name and "Cross Country" down the time slot column through the time for which you plan to fly. Please refer to the Cross-Country Policy to insure that all responsibilities for cross-country flights have been fulfilled. Only one of the two-place ASK-21 gliders can be signed up for cross-country at a time.
  8. Cross-country flights can be SSA/FAI Badge flights, record attempts, NISC race flights or flights away from the glider club field chosen to be appropriate for the skill level of the member pilot.
  9. It is important to remember that the gliders are owned and are to be shared by all members. The cross country reservation policy should be used with care to make sure that members who want to use the gliders have a fair chance to do so. However, there is no set limit to the amount of flying that a member is allowed to do (including cross-country). The idea is to have the gliders being flown - not sitting in the hanger.
  10. Re-lights are allowed, but if it becomes obvious that you can’t complete your task, you must release the glider for use by the other members.

Minimum Pilot Requirements For Flying or Towing as Pilot in Command in CGC Powered Aircraft    



A pilot not meeting the requirements, MAY be able to fly the airplanes, by being listed as a "named pilot" on the insurance policy after application through the CGC Operations Officer to the insurance company and meet certain requirements as prescribed by the insurance company.

Qualified CGC Pilots are not required to hold a Commercial Pilot Certificate to tow CGC members.
