For many years, aviation instructors have admonished students for not removing the pitot tube cover prior to flight. Pitot tubes consist of a specialized hollow pipe connected to an air pressure measuring tool. By measuring air pressure from the pitot tube and a static port on an aircraft, pilots can determine their airspeed quickly and easily. While navigation technologies like GPS can be used to determine groundspeed, the pitot tube is one of the only reliable ways for a pilot to determine the airspeed of his or her aircraft.
Unfortunately, pitot tubes are popular with a variety of pests. If insects like wasps or ants make their home inside a pitot tube, the air speed indicator in an aircraft will stop working.
To prevent this from happening, pilots use a pitot tube cover to protect this valuable instrument while on the ground. Since many pilots forget to remove this cover, most pitot tube covers come with a prominent warning in neon colors. This warning, usually dubbed "Remove Before Flight", provides an additional level of protection for pilots.
