Degree of motion terminology for special aviation movements
The opposite of climb is &quot;descend&quot; (that's an easy one).
The second one can be &quot;translate&quot; or possibly &quot;slew&quot; but I think the most appropriate word is &quot;slip&quot; as in sideslip.
Translate is a controlled movement from one place to another, and slew is an uncontrolled one according to Oxford, but when you work the &quot;slew&quot; switch for a directional gyro system, it's a controlled action, so there you go.
However, those terms apply to a stationary object that starts to move sideways, &quot;slip&quot; describes lateral non-turning movement of an airplane sideways when it's already moving forward, so this is probably the best definition.
