Digital Air Data Ramp Tester - RVSM
The Model AD473 Air Data Test Set is a Digital Test Set designed to test and certify Aircraft Pitot and Static Systems from -2000ft. to in excess of 60,000 ft., Airspeeds from 0 to 450 Knots.
The Model AD473 Air Data Test Set is a Digital Test Set designed to test and certify Aircraft Pitot and Static Systems from -2000ft. to in excess of 60,000 ft., Airspeeds from 0 to 450 Knots. The tester also has the capability of choosing from 20 other measurements of pressure and vacuum. The Internal pressure relief valve limits the pressure to 5.3 PSI (450 KNOTS.) This will help prevent damage to sensitive instruments in the aircraft. Standard read outs are: Altitude, Air Speed, Rate of Climb, and Mach Number. QFF and QFE the digital display is a backlit LCD graphics with variable size to suit the number of values being displayed. Auto display leak test functions. Despite the versatility of this unit, it's very easy to operate. Most features are grouped under single command buttons and the unit is menu driven with clear prompts. The unit weighs approximately 30 lbs.

Accuracy

Basic figures include non linearity, hystersis, and repeatability. Regular use of the "Zero" key for the differential measurements assumed. All values are +1 - 1 digit.

Scale Accuracy

Barometric Range: 11.6 PSI - 16.7 PSI Absolute +/- 0.002 PSI 23.405" Hg - 34.098 1-Hg
All Other Ranges: +/- 0.02% of reading +/- 0.01% F.S. These figures include linearity, hystersis and repeatability, and temperature effects above 50 Deg. F to 86 Deg. F

Stability

Stability over 12 months • 100 ppm / 01%

Calibration

The AD473 Air Data Test Set is calibrated against precision pressure calibration equipment which is traceable to the National Institute of Standards and Technology (NIST.) It is recommended that the unit be recertified at least once every 12 calendar months.
