Variable pitch (two-position) airscrew
352. The variable pitch airscrew control must be in the coarse pitch position for all flight conditions other than for take-off and when gliding in to land with the engine throttled; in these cases, the control should be in fine pitch in order to permit an emergency take-off if necessary. On no account should running up on the ground be done with the airscrew in the coarse pitch position.
