Pitot-static instrument to determine airspeed for an aircraft

An aircraft comprising:

• a fuselage;
• a first nacelle coupled to the fuselage;
• a pitot system coupled to the first nacelle, wherein the pitot system includes a body and a hermetically sealed chamber coupled to the body, wherein an inlet port in the body is in fluid communication with a movable barrier of the hermetically sealed chamber, and wherein one or more first sensors configured to generate first signals corresponding to impact pressure exerted on the movable barrier are coupled to the movable barrier;
• and
• a computer configured to receive the first signals from the one or more first sensors.

A method comprising:

• causing, by motion of an aircraft relative to air, the air to exert an impact pressure against a movable barrier of a hermetically sealed chamber positioned in a body of a pitot system;
• generating, via one or more first sensors of the aircraft, first signals based on deflection of the movable barrier due to the impact pressure, wherein the first signals correspond to stagnation pressure of the pitot system;
• and
• determining, via one or more processors of the aircraft, an indicated airspeed of the aircraft based on the first signals and based on second signals from a static pressure system.
