Summary

Deck angle refers to the angle between the aircraft's longitudinal axis and the horizon line during flight. It is most commonly referenced during takeoff and landing phases, or in level flight when pitch attitudes differ due to aircraft design or operational configuration.

This angle is not necessarily the same as pitch attitude indicated on an artificial horizon, because pitch attitude is measured relative to the aircraft's movement through the airmass, while deck angle refers more to the aircraft's body axis relative to the Earth’s surface.

Deck angle is especially important in aircraft carrier operations and in flight test or performance evaluations where visual references are limited or when evaluating pilot visibility over the nose.
