Laversab Model 6580/6580-HA

Automated Air Data Test Set

The 6580 & 6580-HA Air Data Test Sets are rack-mount units with built-in pressure and vacuum pumps featuring quiet operation. These test sets can be used to calibrate altimeters, airspeed / Mach indicators, Climb indicators, Flight data recorders, Air data computers, and EPR indicators. The high accuracy of these units meets all RVSM requirements. Also, they need to be calibrated only once a year. The use of “Profiles” makes it possible for the operator to run through a test using only a single key on the front panel keypad of these units.”



  • RVSM compliant The high accuracy of the tester and NIST-traceable calibration make the tester fully RVSM-compliant.
  • Calibration period: 1 year.
  • Pressure & Vacuum system the unit includes dual vacuum pumps and a pressure pump for higher reliability. The pressure system includes a membrane dryer and filter to provide clean dry air for the entire system. No external pumps are required. Internal pumps have a minimum life of 5000 operating hours.
  • 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 ±0.001 inHg.
  • “Jog” and “Hold” features Set-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.
  • Programmable limits User-programmable limits for altitude, airspeed, Mach and VSI provide protection to the aircraft.
  • Ground” feature Brings 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..
  • Local display and keypad The 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.
