Greetings - Thank you for your interest in Towing Gliders for the Regina Gliding and Soaring Club.
This information should answer most of your questions about towing gliders with a Bellanca Scout at the Strawberry Lake Gliderport. If you are not already aware, gliding and soaring have the distinction of providing the participants with undescribable enjoyment. We as power pilots know only too well the joy of flight, but until we are able to master the sky in engineless flight, we know only half of what is possible.
Another bonus to those who participate in engineless flight, is membership to a fraternity of people dedicated to the sport and each other. Gliding and Soaring are as much social activities as they are sports. From their very nature, they require teamwork and participation in order to make them work. They need instructors, glider handlers, and importantly, tow pilots.
All too often, Tow Pilots get into the rut of just doing a job. To the gliding club, it is an important job, and they want you to feel as much a part of the team as they are. They appreciate the job you are doing, and want you to enjoy yourself as much as they do.
Our club is affiliated with both Provincial and Federal Associations. The Federal association is known as the Soaring Association of Canada (SAC). This affiliation allows us to insure our equipment at extremely reasonable rates. We get charged a lump sum for each aircraft, and the club distributes this cost evenly between it's members. If you are towing gliders for the club, you must become a member of the club to be insured on our aircraft, and in so doing, pay your share of the insurance for the tow-plane.
We would like to welcome you into our club, and hope that if you join, you will participate at all our picnics, banquets, and any other get togethers we have. There are two types of membership available to you at this time : a strictly Tow-pilot membership, at $80.00 per year, or a Full-flying membership, at $145.00 per year.
Our Full-flying members may obtain free instruction in the art of flying gliders, and the use of our club gliders during normal gliding times. There is an hourly fee for the rental of our gliders and a charge for the tows, but is only enough to cover the maintenance and fuel costs.
The club has a few incentives for those who join as tow-pilots. First, for each 20 gliders you fly tow, you will be entitled to a free dual glider trip of up to 30 minutes per trip, at the discretion of the Duty Instructor (You may not fly the gliders solo unless you are a full-flying member). These trips are not transferable and must be taken by the end of the gliding year.
Second, the club will rent the tow-plane to you at an extremely reasonable rate ($150.00/hr) so that you may upgrade yourself to meet our time requirements for towing. Of course, this must be at times other than when gliding is taking place, and must be organized with the Chief Tow Pilot.
Third, if you go to the trouble of qualifying for towing, and do your share of tow duty, your first three hours of rental will be reimbursed. And after six days of towing for us, your $80.00 SAC fee will also be reimbursed.
If you have read this far, you are probably starting to get intrigued by our club, and are developing a desire to take part yourself.
We have a lot of fun in our club, but as should be the case with any flying operation, safety must be a key issue. We have a terrific safety record, and is only maintained because of the dedication we show towards it. We keep our aircraft well maintained. If any of our members notice any irregularities, they are brought to the attention of our maintenance chairman, and rectified immediately. We as members of the club are the owners of the equipment we fly, and take great pride in it. We keep it clean, and don't try to show off with it, pushing it's design limits.
A Tow-Plane must work very hard to accomplish it's task. During tow, the engine get's extremely hot, and must be intricately monitored during all phases of the tow. We tow at approximately 65 MPH. After tow, we throttle back to 2100 RPM, and descend at approximately 100 MPH. These numbers have proven to evenly cool the engine, and prevent cylinder problems. Landings should be done with flap, and may be either wheelies, or stall landings.
An extremely important part of the tow, is the takeoff. As you may know, we tow with a 200-250 ft 3/8 inch nylon rope. A weak link of 1/4 inch rope is attached at both ends of the rope to give way under great pressures.
When the takeoff phase commences, the slack in the rope is first taken up slowly. After this, power is applied slowly and evenly. During this application, the stick is held fully aft (to prevent nose-over if the rope breaks). Slow even application is necessary to prevent the glider from banging it's tail or nose after the rope is tight. After full throttle is achieved, the elevator is centralized so that the airplane tail will come up, and the airplane should lift off between 55 and 60 MPH.
Shortly thereafter, airspeed should be adjusted to 65 MPH when towing a non-fibreglass glider, and 70 MPH when towing a fibreglass glider, and maintained through the tow.
The following pages of this booklet present:
1) All flying shall be conducted in accordance with Air Regulations. If a club rule is found to be in conflict with Air Regulations, the Air Regulations shall supersede the club rule.
2) All flying in club gliders must be authorised by the CFI or the duty
instructor. An instructor must be on duty at the field before Club equipment may
be used except:
3) Student pilots may soar only after they have been briefed and approved for soaring by the duty instructor on the day in question. Soaring time limit 30 min. unless approved for a longer period. All flying must be carried out within the specified radius of the field (ie: in sight of the instructor, in the upwind quadrant).
4) Licensed pilots, Flying and Sustaining Members only, may go on cross-country flights after their log books have been certified by the CFI. For certification, a pilot shall meet RGSC cross-country requirements.
5) All club members shall have annual check flights (at least two) and have their log books endorsed by the attending instructor before flying solo at the beginning of the season, except those excluded by the CFI.
6) Pilots may fly club aircraft as pilot-in-command only after complying with RGSC checkout requirements for that aircraft.
7) Incipient spins and stalls shall be conducted at safe altitude and shall be recovered by 2000 ft AGL.
8) All pilots must have a minimum of ten dual flights from our field before flying solo in club equipment unless otherwise authorised by the Duty Instructor.
9) No aerobatics shall be done in any club aircraft.
10) Tow aircraft shall not be started unless a licensed pilot approved by the Chief Tow Pilot is at the controls.
11) Pilots and student pilots must report immediately any un-serviceability or unusual landing strains to the Duty Instructor.
12) The duty instructor has the authority to check the flying ability of any club member wishing to fly, and such checks may include a request that the pilot demonstrate his ability to handle the aircraft under existing conditions.
13) When in disagreement with a ruling of the duty instructor, follow his ruling (for he is in charge of the operation). You may take it up later with the CFI.
14) Cross country retrieves with club tow planes shall only be made from aerodromes and only when it does not interfere with normal flying operations.
15) No passengers are to be carried in the tow planes except for flights authorised by the Chief Tow Pilot and Duty Instructor.
16) All pilots must have their licenses and Log Books with them and be prepared to show them upon request to the Duty Instructor.
17) Either the Duty Instructor or the Tow Pilot may halt operations if either feels that it is unsafe to continue.
18) The duty instructor is responsible for overall supervision of all flying and airfield activities.
19) All landings shall be made within the runway marker lines, unless unsafe to do so.
20) A standard rectangular circuit should precede all landings.
21) Every member has the responsibility of ensuring that when he flies or intends to fly, that he is not under the influence of alcohol or drugs, which include such medication as decongestants. Anyone contravening Air Regulation #408 may be grounded.
22) Pilots may not thermal or execute 360 degree turns after joining the circuit.
23) When flying a club single-seat, a parachute shall be worn. Private owners are urged to do the same in their ships.

29) Aircraft must be inspected prior to the first flight of the day by a pilot approved for the same.
30) Only those persons with a Radio Operator's license may operate a VHF communications radio in any glider or on the ground.
31) Avoid radio chatter. Only terminology specified by the DOC is to be used.
32) New glider retrievers must be briefed on retrieve procedures, and must be under the supervision of experienced personnel when retrieving gliders.
TOW AIRCRAFT - ABORT ON TAKE-OFF
Should the tow aircraft abort on the runway due to an emergency, the tow pilot shall release the glider at once and turn toward the left side of the runway so that, should it be necessary, the glider may pass the aircraft on the right.
EMERGENCY RELEASE PROCEDURES
TOW AIRCRAFT - Should the tow aircraft require the glider to release, the aircraft pilot shall rock the wings vigorously. On seeing this signal, the glider pilot shall release immediately. Should the Tow aircraft be unable to give this signal, the tow pilot may release the glider at the tow aircraft end. The glider pilot should immediately release the tow rope from the glider, turn right and maintain level flight to avoid the tow rope and to prevent it from encircling the glider.
GLIDER - If the glider pilot is unable to release, employing normal release procedures, he shall fly the glider well to the left of the tow aircraft and rock the wings. On seeing this signal, the tow pilot shall return the glider to the release area and release the tow rope at the aircraft end. The glider pilot shall try several more release attempts to free the tow rope and carry out a landing using a steep approach, on the assumption that the tow rope is still dragging below and behind the glider.
NON_RELEASE - In the event that neither the tow aircraft nor the glider can release, the tow pilot shall perform a power-on approach and landing with the glider in tow. The tow pilot shall extend his ground roll to prevent the glider from overtaking the aircraft on the runway. The glider pilot shall use spoilers on the approach to increase the drag, and use maximum braking on the ground roll.
