What does a pitot tube do on an airplane?
Basically, a pitot tube is used in wind tunnel experiments and on airplanes to measure flow speed. It’s a slender tube that has two holes on it. The front hole is placed in the airstream to measure what’s called the stagnation pressure. The side hole measures the static pressure.
How many pitot tubes does a 747 have?
four pitot tubes
By measuring the difference between these pressures, you get the dynamic pressure, which can be used to calculate airspeed. There are four pitot tubes available in the Boeing 747-8 Aircraft. Two pitot tubes are placed in the right side of the aircraft and other two on the other side of the aircraft.

What is the difference between pitot tube and pitot-static tube?
The pitot tube consists a single inner tube to measure the stagnation pressure. The pitot-static tube, also known as Prandtl tube measures both stagnation pressure and static pressure using the same device. It consists two holes in the tube.
Which instrument is affected if the pitot tube is blocked?
airspeed indicator
If you did have a blockage, would you recognize it? The airspeed indicator uses ram air from the pitot tube, compared with static air from the static vent(s) to display airspeed. A blocked pitot tube will only affect the airspeed indicator. Your airspeed will initially not increase as you accelerate down the runway.
Why are there two pitot tubes on the tail?
There are two pitot tubes on the tail that are for the ” elevator feel and centering unit ” (pdf; page 8). The elevator feel computer provides simulated aerodynamic forces using airspeed (from the elevator pitot system) and stabilizer position. Feel is transmitted to the control columns by the elevator feel and centering unit.
Where is the Tat probe located on a 737?
The elevator pitots are located on the tail-fin. The 737-1/200 also has a second TAT probe on the RHS. Located on the stbd flightdeck wall, near the F/O’s sun visor, the static source selector is only present on older aircraft (approx before l/n 1600 c1988).
Where is the airspeed measured on a 737?
Is the airspeed measured at the tail view-able from the cockpit? There are five sets of pitot tubes on the 737, organized into two groups, the pitot tubes on the nose are used for airspeed measurements, independent for the pilot and copilot and one as a backup.
Where are the elevator pitots located on a 737?
Capts pitot. Notice that the pitot heat captions on the overhead panel (see below) are in a similar orientation. The elevator pitots are located on the tail-fin . The NG static ports were moved from the nose to the mid-fuselage. The exceptions are the freighters.
