Contexto
The pitot-static probe (Figure 3.2) is exposed in the free air-stream beyond the aircraft boundary layer and measures static pressure (i.e. free air-stream pressure) and total pressure (static pressure, and impact or dynamic) pressure. The sensor outputs are passed via an electronic barometer to the air data computer (ADC). The ADC computes pressure altitude and Mach number from these two measurements.
When the velocity of the air is slowed, static pressure increases, resulting in compressed, high-pressure air. The high pressure air then passes through the compressor manifold where it is distributed to the combustion chamber.
