PITOT STATIC TESTERS & EQUIPMENTS

 

 

 

 

What is a PITOT STATIC tester ?
A Pitot Static tester is a pressure generator and pressure measurement instrument which can simulate altitude and speed of aircraft
on-board equipments.

The name « Pitot Static » comes from the « Pitot & Static » tubes on aircraft where is connected the testing instrument.
In the world, two names are used :
• Pitot/Static Tester
• Air Data Test System (ADTS)

Why would you need a Pitot Static tester ?
Flying conditions need to be simulated for on-board equipments to be certified, and this occurs when those are manufactured, repaired, or integrated into the aircraft.
There are two kinds of Pitot Static testers:
• For workshops to test on-board instruments when they are manufactured, repaired or calibrated.
• For hangar or tarmac to verify instrument directly on aircraft.

 

How does a Pitot Static tester work ?

A Pitot Static tester generates a pressure or a partial vacuum to simulate altitudes and speeds.
The following on-board equipments are subject to Pitot Static testing:
• the altimeter for altitude
• the air speed indicator for speed
• the rate of climb indicator for vertical speed
• the flight computers and aero-dynamic computer
• the computers sensors
• the safety sensors
• the pressure switches
On the aircraft, all these equipments are connected externally to Pitot tubes or to a hole on the aircraft « skin ».
