No, because the whole system is spinning together. Your helicopter is hovering at 0 mph
relative to the planet, so it is in fact spinning at 1000 mph ( a little bit more actually*) around the planet.
Actually the concept of immobility has no meaning. All bodies move in relation to other bodies, even galaxies. There is no fixed reference point in the universe.
* It has the same angular velocity as the planet's surface, but because it is further from the spin axis, its linear velocity is higher.
