The correct answer is c. "Ground loops" happen when a pilot applies too much back pressure on the control wheel. This engages the elevators too much and pushes the nose of the plane higher, until the plane flips right over.

Advanced Flight Training Test #3

You are practicing formation flying at night. There are four planes in a "box" or "diamond" formation. Such formations allow your air gunners to provide maximum protection to all planes. You are the centre rear aircraft. Suddenly you lose all visibility. You have flown into a cloud bank and all light has been cut off. All you have to fly by are your instruments. Your heart races, and droplets of sweat roll down your back. Blind formation night flying is incredibly dangerous. The odds of a fatal collision are extremely high. As the minutes pass, you realize that the cloud bank must be very deep - you still cannot see a thing.

What's best thing to do?

a. Slow down, lose altitude and drop out of the formation.

B. Hold your course and wait for instructions from the lead aircraft.

C. Turn on your landing lights and make a sharp turn to port to get out of the formation

D. Turn on your lights, pull back on the throttle to increase engine power, deploy flaps and make an emergency climb.
