Static Port Warning Decals — Aircraft Airworthiness
CARs Part V — Aircraft Maintenance Standards · Federal — Canada
§The Law
CARs Part V — s.571 Airworthiness — CARs Part V — Aircraft Maintenance Standards
“Static ports must be protected with approved covers and marked to alert ground crews to remove covers before flight. Blockage of static ports causes altimeter, airspeed, and VSI failure and is a major airworthiness hazard.”
View official regulation text✓Plain English
The static port is a small flush hole in the aircraft skin that feeds the altimeter and airspeed indicator. A warning placard near the port alerts maintenance crews not to paint over it, plug it, or leave protective covers on before flight.
