if feasible. Think about water requirements to keep hydrated  and the inevitable physiological requirement. Use aircraft  trim to ensure the maximum tow speed of the glider is not  exceeded and to help reduce pilot fatigue. Two-way communication between the glider and the tow  plane is essential during cross-country tows. Ensure portable  radios and glider batteries are fully charged prior to the flight  and conduct a radio check as part of your pre-flight activities.  [Figure 12-16] The following actions should be taken in the event the tow  plane has a power failure on the runway during the takeoff roll:  The pilot of the tow plane should continue the takeoff  eliminating a collision hazard with the glider. The pilot of the glider will normally release and descend  straight ahead or maneuver using slight turns to make a  specific forced landing. Because of airport obstructions in  close proximity to the airport, the options available for a  tow plane or glider land out may be limited. Discuss these  options during the pilot briefing or safety meetings. Again,  a plan will go a long way in ensuring a successful land out  as a result of a takeoff emergency. The glider can more than likely return to the field in the event  of engine failure or rope break. Since the tow plane requires  considerably more altitude to return to the field in the event of  a power failure, the pilot should have a specific plan in mind  that includes pre-selected landing areas for each runway. The tail of the tow plane may be lifted if the glider climbs  excessively high during takeoff. Should this happen, the  application of full-up elevator on the tow plane may not be  sufficient to prevent an accident. The tow pilot must be ready  to pull the release handle in order to regain control of the tow  The key to ensuring successful emergency management is  the development of an emergency plan. Prior to takeoff,  an emergency release point should be selected somewhere  along the takeoff runway. This release point should leave  sufficient room to land straight ahead, using normal stopping  techniques, in the event conditions are such that a safe takeoff  with the glider in tow cannot be completed. During the initial climb out, the pilot of the glider will be  noting certain altitudes that correspond to actions he or she  will take in the event of a low-altitude emergency.

On a cross-country tow, the tow pilot and glider  pilot should have two way communication using portable radios. 12-11 •  The glider should release or be released by the tow  plane and, if possible, maneuver right of the runway. •  The tow plane should maneuver to the left of the runway  if space is available. (Realize each individual airfield  layout and obstacles may dictate an alternate procedure,  so take the time to plan your actions prior to takeoff.) •  Survey the abort area carefully and know where  you can exit the runway (grass or taxi-way) without  causing a hazard. Always have a plan.  •  Realize the glider will probably be airborne, therefore  try and give the glider as much space as possible to  land on the remaining runway and brake to a stop. •  Know the stopping characteristics of the glider you  are towing. Some models have very effective brakes,  others do not. Tow Plane Power Failure on the Runway During  Takeoff Roll
