Crab into crosswind during  ground tow climb-out. Towline drifts toward runway  centerline after release. WIND from standing start to lift-off may be as short as 3 to 5 seconds.  After the initial lift-off, the pilot should smoothly raise the  nose to the proper pitch attitude, watching for an increase in  airspeed. If the nose is raised too soon or too steeply, the pitch  attitude is excessive while the glider is still at low altitude. If  the towline breaks or the launching mechanism loses power,  recovery from such a high pitch attitude may be difficult  or impossible. Conversely, if the nose is raised too slowly,  the glider may gain excessive airspeed and may exceed the  maximum ground launch tow speed. The shallow climb may  result in the glider not attaining planned release altitude. If  this situation occurs, the pilot should pull the release and land  straight ahead, avoiding any obstacles and equipment. As the launch progresses, the pilot should ease the nose up  gradually  [Figure 7-21, position B]  while monitoring the  airspeed to ensure that it is adequate for launch but does  not exceed the maximum permitted ground launch tow  airspeed. When optimum pitch attitude for climb is attained,  [Figure 7-21, position C]  the glider should be approximately  200 feet AGL. The pilot must monitor the airspeed during  this phase of the climb-out to ensure the airspeed is adequate  to provide a safe margin above stall speed but below the  maximum ground launch airspeed. If the towline breaks,  or if the launching mechanism loses power at or above this  altitude, the pilot has sufficient altitude to release the towline  and lower the nose from the climb attitude to the approach  attitude that provides an appropriate airspeed for landing  straight ahead. As the glider nears its maximum altitude  [Figure 7-21,  position D] , it begins to level off above the launch winch or  tow vehicle to reduce the rate of climb. In this final phase of  the ground launch, the towline is pulling steeply down on the  glider. The pilot should gently lower the nose of the glider  to reduce tension on the towline and then pull the towline  release two to three times to ensure the towline releases. The  pilot feels the release of the towline as it departs the glider.  The pilot should enter a turn to visually confirm the fall of  the towline. If only a portion of the towline is seen falling  to the ground, it is possible that the towline is broken and a  portion of the towline is still attached to the glider. If pulling the tow release handle fails to release the towline,  the back release mechanism of the towhook should  automatically release the towline as the glider overtakes and  passes the launch vehicle or winch. moving forward as the long towline is tautened. Elasticity in  the towline causes the glider to creep forward as the towline  is tightened. For this reason, the towline is left with a small  amount of slack prior to beginning the launch. It is important  for the pilot to be prepared for the launch prior to giving the  launch signal. If the launch is begun before the pilot gives the  launch signal, the glider pilot should pull the towline release  handle promptly. In the first several seconds of the launch,  the glider pilot should hold the stick forward to avoid kiting.  During the launch, the glider pilot should track the runway  centerline and monitor the airspeed.  [Figure 7-21, position A]  When the glider accelerates and attains lift-off speed, the  glider pilot eases the glider off the ground. The time interval  The pitch attitude/airspeed relationship during ground launch  is a unique flight experience. During the launch, pulling  back on the stick tends to increase airspeed, and pushing  forward tends to reduce airspeed. This is opposite of the  Climb-Out and Release Procedures 7-16 Figure 7-20.
