Model 6600-M4: Military Pitot Static Tester with 3 Outputs

The 6600-M4 Automated Tester is ideal for use on military aircraft with SmartProbes™ capable of measuring AOA using Air Data. The tester has one Static output (Ps1), one Pitot output (Pt) and a third output (Ps2) which can be used to simulate either AOA or AOS. Using the small and light-weight Remote unit a user can operate the tester from the cockpit and test the entire pitot and static system of the aircraft. The tester includes built-in vacuum and pressure pumps and emergency manual bleed-down valves. The high accuracy of this unit meets all RVSM requirements. Also, it requires no maintenance other than 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 Remote unit.

Features

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, differential pressure, 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. All valid parameters of all three outputs are clearly displayed simultaneously on a single screen on the remote.
Manual Vent
The tester includes precision metering valves to enable manual venting of all three outputs, in the event of power-loss

Applications

Ideal tester for use with aircraft equipped with SmartProbe™ 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 SmartProbe™
Leak-checks and Air-data-system accuracy-checks on all RVSM aircraft (military and commercial) including aircraft with SmartProbe™. 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-M4H 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.
