Target Aircraft

Military Aircraft.

Target Application

Pitot-static system checks.

Description

The Model 6300-M4 is designed to test military aircraft. It is used to perform leak checks and RVSM accuracy checks on the Pitot-Static systems — including altimeters, airspeed/Mach indicators, VSI’s, air data computers, autopilots — and can be done at low airspeeds.

The 6300-M4 can be tested from the cockpit. The tester includes built-in vacuum and pressure pumps and emergency manual bleed-down valves. It can use profiles to run through an entire test range using a single key.

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.

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 and ±0.1 knot.

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.

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.

Pressure & Vacuum source

Built-in high-capacity dual vacuum pumps and pressure pump provide the pressure and vacuum source for the unit. The pressure system includes a filter and membrane dryer to provide clean dry air for the entire system.

Manual Vent

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

Calibration period

1 year.

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.

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.

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.
