Static port
A flush opening on the fuselage that supplies ambient air pressure to the altimeter, airspeed indicator and vertical speed indicator. Static ports must be masked before washing and unmasked afterwards.
What it means
A flush opening on the fuselage that supplies ambient air pressure to the altimeter, airspeed indicator and vertical speed indicator. Static ports must be masked before washing and unmasked afterwards.
Why it matters
Product or water entering a static port produces false instrument readings. Masking is not optional, and neither is a documented unmasking check.
