At present, the nose in Europe and America is often made of composite materials at one time, so pitot tubes are usually not installed on the nose, but are usually moved to the left or right of the windshield or at a lower position.

Pitot tube is the simplest mechanical testing equipment, with low cost, reliable operation and no need of replacement. At present, there are some electronic sensors or inertial navigation devices that can measure airspeed, but they are all standby devices.

Besides, who told you upstairs that there is no pitot tube in F22? F22 only has no nose pitot tube, and there are two L-shaped pitot tubes on the side.

At present, the static pressure and total pressure of airflow are used as the original parameters to measure the flight speed and altitude of aircraft. The total static pressure system of aircraft consists of the total static pressure pipe (pitot tube) that collects the total static pressure of airflow, the instruments and equipment that work with the total static pressure and the pressure transmission pipeline between them. This system is also called aircraft pressure measurement system. The complexity of the system mainly depends on the type and size of the aircraft, the number of main flight instruments and the types of instruments. But structurally, it includes a full pressure port, a static pressure hole, a heating device and a drainage hole for drainage.

On the plane, in addition to the pitot tube, there are also emergency master pressure pipes and emergency static pressure holes. Once the pitot tube fails, they will provide the total pressure and static pressure of airflow respectively to ensure the normal work of related instruments and equipment. Even if advanced to F22, it is impossible to cancel this mature speed measuring device and replace it with unreliable electronic equipment. Air data computer is more advanced than other computers at most.
