GPC - Glider Pilot Certificate Abnormal and Emergency Procedures Questions and Answers

Question 1

During a winch launch, the cable breaks when the glider is at an altitude of approximately 150 feet AGL with a steep nose-up attitude. Which of the following actions is the most critical and must be performed FIRST?

Accepted Answer

Promptly and positively lower the nose to establish a safe flying speed.

Answer

The most immediate danger after a winch cable break at a high pitch attitude is a stall followed by a potential spin. The pilot's first and most critical action must be to lower the nose to reduce the angle of attack and establish a safe flying speed. All other actions, such as releasing the remaining cable or planning the landing, are secondary to flying the aircraft and preventing a loss of control.

Question 2

A pilot recognizes that their glider is in a spiral dive, indicated by a steep bank, a low pitch attitude, and a rapidly increasing airspeed. Which sequence of actions is correct for recovery?

Accepted Answer

Close the spoilers, use coordinated aileron and rudder to level the wings, and then gently ease the control stick back to recover from the dive.

Answer

In a spiral dive, the aircraft is not stalled, but is in a steep, descending turn with increasing airspeed. Pulling back on the stick before leveling the wings will tighten the spiral and could cause a structural failure due to high G-loads. The correct procedure is to first close spoilers (if open), then level the wings to stop the turn, and finally, gently ease out of the dive to avoid overstressing the airframe.

Question 3

A VFR-rated glider pilot inadvertently flies into a cloud and loses all outside visual references. To prevent a spiral dive and exit the instrument meteorological conditions (IMC), what is the most appropriate course of action?

Accepted Answer

Trust the instruments, make a gentle 180-degree turn, and maintain a constant airspeed, keeping control inputs smooth.

Answer

When a VFR pilot enters IMC, spatial disorientation is the greatest threat. The correct procedure is to trust the instruments, not bodily sensations. The primary goal is to initiate a gentle, standard-rate 180-degree turn to reverse course and fly out of the cloud. The pilot should make only small, smooth control inputs while focusing on the basic instruments to maintain a constant airspeed and prevent over-controlling, which can lead to a spiral dive.

Question 4

While on the final approach for landing, a pilot finds that the spoilers/airbrakes are jammed and will not extend. The glider is currently high on the ideal glide path. What is the recommended corrective action?

Accepted Answer

Initiate a forward slip to increase drag and steepen the descent path without a significant increase in airspeed.

Answer

A forward slip is the primary method for increasing the rate of descent when spoilers or airbrakes are inoperative. By applying rudder and opposite aileron, the pilot presents the side of the fuselage to the relative wind, creating significant drag. This allows for a steeper, more controlled descent angle without the airspeed increasing excessively, enabling the pilot to correct a high approach and still land in the desired area.

Question 5

A pilot inadvertently enters a spin to the left. Which of the following describes the most widely accepted and correct recovery procedure for most gliders?

Accepted Answer

Apply full right rudder, neutralize ailerons, and move the control stick forward until rotation stops.

Answer

The standard spin recovery procedure involves three distinct actions. First, apply full rudder opposite to the direction of rotation to stop the yawing motion. Second, neutralize the ailerons. Third, move the control stick forward to reduce the angle of attack and break the stall. Once the rotation stops, the controls are neutralized, and the pilot recovers from the resulting dive.
