1

Question 5

Light turbulence =

Answer 5

Momentarily causes slight erratic changes in altitude and/or attitude. Chop causes slight rapid rhythmic bumpiness

Question 6

Moderate turbulence =

Answer 6

Similar to light but of greater intensity. Change in altitude/attitude but aircraft in positive control. Variation in IAS

Question 7

Severe turbulence =

Answer 7

Causes large, abrupt changes in attitude/altitude. Causes large variation of IAS. Aircraft maybe momentarily out of control

Question 8

Extreme turbulence =

Answer 8

Extreme: Aircraft is violently tossed about and is practically impossible to control. May cause structural damage

Question 9

Where can guidance for action to take in turbulence be found?

Answer 9

FOM 7-81
