The centrifugal and coriolis forces don't do work. That does not mean that these apparent forces do not affect the behavior of a plane. It just means that the effect does not exhibit itself in the form of a change in energy.

The original question informed about airplane velocity, and given the indications that the questioner had no physics background I took that as a question about airplane
speed. (Still, technically the word 'velocity' includes direction; the usual definition of 'velocity' is as vector quantity.)
In the wider sense, taking velocity as vector quantity: the rotation-of-Earth effect does have influence on direction of motion.
In the case of the Eötvös effect: if the airship is trimmed for neutral buoyance while flying eastward, and the airshap makes a U-turn, it will have to be retrimmed. If not then the Eötvös effect will make the airship lose altitude, quite a dangerous situation.
When an airship loses altitude gravity is doing work. This illustrates that the Eötvös effect does not exclude change of energy.
