A combination pickup that samples both pitot pressure and static air pressure is known as?

A combination pickup that samples both pitot pressure and static air pressure is referred to as a pitot static head. This device plays a crucial role in measuring airspeed and altitude in aircraft. The pitot tube measures dynamic pressure, which is indicative of the aircraft's speed through the air, while the static port measures static pressure, which is necessary for altitude calculations.

The pitot static head combines these two measurements to provide the necessary data for airspeed indicators and altimeters. By integrating both pressures, pilots can accurately assess their flying conditions and make informed decisions.

Other options do not properly describe this type of pickup. Static head typically relates to measurements made without dynamic input, while a Benson sensor is not widely recognized in aviation terminology related to pressure measurements. A dynamic pressure sensor, on the other hand, would measure only the dynamic pressure component, missing the ability to provide both necessary readings for aerospace navigation and performance calculation. Thus, the term "pitot static head" is the most accurate and relevant to the function described.
