Which hazard do mountain waves present to aircraft?

  • A.A sudden increase in air density in the descending part of the wave that overloads the wing structure
  • B.Severe turbulence and strong vertical currents
  • C.Rapid airframe icing caused by the very high liquid water content of the lenticular cloud at the crest
  • D.Loss of navigation signal

Answer: B

Rotor turbulence beneath the wave crests and vertical currents of several metres per second can exceed the climb or descent capability of an aircraft, and several accidents have been attributed to them. Lenticular cloud is generally smooth and not a major icing hazard. Navigation and air density are not affected in the way suggested by the other options.
