A pilot who does not stall and actually completes a course reversal now faces his third challenge. If he was high enough that he could hold a 30-degree bank throughout the turn, depending on the wind direction and velocity, he is now approximately a half-mile to one side of the runway heading downwind, so his groundspeed is greater. He has to continue his turn for another 30 degrees and then glide for up to a minute more to actually make it back to the runway. If he used a 45-degree bank, the turn would only take about 15 seconds, so he would be much closer to the runway and would only have to turn about 10 degrees further and glide a much shorter distance back to the runway. A pilot who manages to meet all these challenges — pushing hard, banking steeply and gliding back to the runway — is now faced with a downwind landing with possible opposing traffic taking off toward him. Pull that one off, and you have become one of the few fortunate pilots to survive turning back to the runway after an engine failure on takeoff.
