Q

What is VMCL?

A

The minimum speed at which the aircraft can be controlled in flight, with one engine inoperative, maximum takeoff thrust on the operating engine(s), and a bank angle up to 5° towards the operative engine.

  • Use to calculate V2 ( V2 ≥ VMCL)
  • Banking towards the operative engine reduces the rudder required to balance the yawing moment.
