Features

RVSM compliant The very high accuracy of the tester and NIST-traceable calibration make the tester fully RVSM-compliant.

Calibration period: 1 year

Automated operation Simply enter the target set-points for altitude and airspeed and the unit automatically achieves the targets, ramping at the programmed rates. Control at the set-point is stable within ± 1 foot, ± 0.1 knot or ± 0.0002 inHg

Programmable limitsUser-programmable limits for altitude, airspeed, Mach and VSI provide protection to the aircraft.

“Jog” and “Hold” featuresSet-points can be “jogged” up or down in small increments. Ramping to a set-point can be put on “hold” and controlled at the current measured value.

“Ground” featureBrings Pitot and Static outputs to ambient “ground” pressure after completing a test.

“Profiles” feature A profile of set-points can be downloaded from a PC, allowing the user to step through the set-points using a single key. Each profile can have up to 50 set-points and 20 profiles can be stored in the unit.

Leak checks Pitot and Static leak-checks can be performed either independently or simultaneously. Three leak-timers can be programmed to perform timed leaks between 1 to 20 minutes. The display of “instant” leak rates provides immediate feedback to the user.

Pressure & Vacuum requirement External pressure (Dry Air only) and vacuum supplies are required. The PVS is ideally suited for providing these supplies.

Local display and keypadThe local display and keypad are the operator interface for the tester. All valid parameters, including altitude, climb and airspeed, are clearly displayed simultaneously on a single screen on the local display.

Applications

  • Ideal tester for use in an instrument-shop for testing and calibrating ADC’s, altimeters, airspeed indicators, VSI’s, cabin pressure controllers, FDR’s and other air-data instruments.
  • Can be rack-mounted in ATE systems
  • The very high accuracy of this tester makes it suitable for use as a convenient Transfer Standard.
