Explanation

Pitot-static instruments are those that use pitot (dynamic) and static pressure measurements: ASI (Airspeed Indicator), VSI (Vertical Speed Indicator), and Machmeter all operate on pitot-static principles. VOR (VHF Omnidirectional Range) is a radio navigation system that operates on radio waves, not pressure. It is fundamentally different from pitot-static instruments.
