Three Outputs
In addition to the Primary Static and Pitot outputs, a third output is provided. This output can be used as a secondary static, a differential static or secondary pitot. This output allows the user to create a second altitude (in feet or mtrs), a second absolute pressure (in inHg or mbar), a differential pressure for simulating AOA (in Diff.inHg or Diff mbar) or a differential pressure for generating a second airspeed (in knots or kmph) to simulate AOS. When the third output is not used, the tester operates exactly like our 2-output tester (Model 6300)

RVSM compliant
The high accuracy of the tester and NIST-traceable calibration make the tester fully RVSM-compliant and suitable for use on all RVSM-compliant aircraft.

Calibration period: 1 year

Automated operation
Simply enter the target set-points for the three outputs 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

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

“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.

“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 12 profiles can be stored in the unit.

Leak checks
Leak-checks can be performed independently on any of the three outputs. The display of “instant” leak rates provides immediate feedback to the user.

Pressure & Vacuum source
Built-in high-capacity dual vacuum pumps and pressure pump provide the pressure and vacuum source for the unit.

Remote unit
The Remote unit is the operator interface for the tester. It is small and light enough to be used in the cockpit. The tester can be turned On and Off from the Remote. All valid parameters, including altitude, climb and airspeed, are clearly displayed simultaneously on a single screen on the remote.

Manual Vent
The tester includes precision metering valves to enable manual venting of the aircraft’s pitot static system, in the event of The tester includes precision metering valves to enable manual venting of the aircraft’s pitot static system, in the event of power-loss


  • Ideal tester for use with aircraft equipped with “smart probes” that have the ability to sense AOA and/ or AOS.
  • Works identically to the 6600 but can simulate higher altitudes and airspeeds. Also, this tester has a wider operating temperature. Therefore this tester is ideal for military aircraft equipped with “smart probes”
  • Leak-checks and Air-data-system accuracy-checks on all RVSM aircraft (military and commercial) including aircraft with “smart probes”. The tester can be used either in 3-output mode or 2-output mode. In 2-output mode this tester operates exactly like our Model 6300-M3.

When the 6600-M4 is used with the OSM (Output Switching Module) it is possible to completely automate leak checks, which can be performed either individually on each port of the aircraft probes, or simultaneously on all ports. Using the OSM makes it easy to isolate leaks and connection of the hoses and adapters to the aircraft is greatly simplified.
