Which flight condition describes a rate of turn that is too great for the angle of bank?

Which flight condition describes a rate of turn that is too great for the angle of bank?

• A. Skid
• B. Slip
• C. Banked Turn
• D. Unbalanced Turn

Answer: (A)

The key idea is that a turn’s rate is set by how much you bank and how fast you’re flying, and the two must be matched for a coordinated maneuver. If the helicopter’s turn rate becomes too fast for the bank angle you’re using, the yawing motion overwhelms the bank action, creating an uncoordinated turn known as a skid. In a skid, the rotor system and flight path aren’t aligned, so you feel a tendency to slide sideways and the turn seems to race ahead of the bank. To fix it, you’d either increase the bank angle or reduce the rate-of-turn with coordinated pedal input so the bank and turn rate match and the ball centers. The other terms describe different situations: a slip is the opposite imbalance (turn rate too slow for the bank), a banked turn is a coordinated, normal turn, and an unbalanced turn is a general lack of coordination without specifying the rate-for-bank relationship.
