Air Data Test Sets and Systems

Ramp or Flight line Air Data Test Sets

D.Marchiori (DMA) manufacture various RVSM Air Data Test Set models for troubleshooting, leak testing and certification of aircraft pitot-static systems. The feature rich MPSXX Air Data Test Set range enable rapid calibration of altimeters, airspeed indicators, mach indicators, vertical speed indicators, Air Data Computers (ADC) and other avionic pitot-static components. Features include:

• RVSM compatible
• Digitally controlled
• Controlled from keyboard or computer interface
• Precise pressure sensors used to achieve high accuracy
• 5,000 hour pumps
• Engineered to minimize power consumption
• Optional internal multiple static and pitot isolators and output ports
• Battery power
• Simple user interface
• Programmable user test sequences
• Bluetooth remote control
• USB port for USB memory device to download test programs and store results
• Automatic calibration software (with PAMBX transfer standard)
• Wide range of options
• Rapid warm-up

Starting with the low cost MPS38B RVSM ADTS the range includes the MPS31C civil ADTS, the MPS27C ADTS and the MPS34C and flightline ADTS with laboratory accuracy. The MPS35C and MPS39C control three pressures separately and independently to verify the Angle of Attack (AoA) as well as Static and Pitot pressures, for use with 'Smart' type pitot tubes. The new MPS40C is a 4 channel ADTS with 2 channels of AoA.

A wide range of options are available for the Air Data Test Sets with some models pre-configured with certain options:

• 28 VDC operation
• IEEE488 control (RS232 control is standard on most models)
• ARINC429 interface
• PDA for bluetooth control
• Multiple isolated static and pitot outputs controlled from the keypad
• ADWIN software for PC control
• Hand held remote control unit
• Encoding altimeter readout
• Extended ranges of 850 or 1,000 kts
• Internal battery
• External battery to extend battery life
• External pressure and vacuum supply

All the ramp/flight line ADTS are portable and can also be used in the laboratory. ADWIN PC software allows control of the test systems from a standard PC. In all models low power consumption generates negligible heat and allows the highest accuracy available today. Optionally the ADTS can be remotely controlled by a PDA Pocket PC with Bluetooth connection (no cables required). The user interface ensures all the functions are easily controlled with a minimum of key strokes. The instruments are all ready for use and within the accuracy band at the conclusion of the initialisation / self test procedure.

All the Air Data Test Sets have battery power either fitted as standard or available as an option (external option for the MPS38b). This allows the test sets to be operated away from ac power or to continue to be used during power failure.

All models are supplied complete with internal pumps running 'on demand' to achieve maximum life duration and low electrical power consumption. Noise level is very low, a welcome feature when the ADTS is used in the workshop.  

30 User test profiles are programmable and executable, each with 26 test points, enabling repetitive tests such as FAR43 testing to easily be performed with high repeatability.

Calibration is accomplished through user adjustment of calibration constants without the requirement for hardware adjustments.

Contact the office to discuss any specific customer requirements such as radio altimeter automatic test.

Laboratory Air Data Test Sets

DMA is a leading manufacturer of Air Data Test Set models for laboratory use achieving the highest accuracy and resolution. The MPS36 is digitally controlled through a keyboard, it uses the most accurate pressure sensors currently available, with a special characterisation for maximum accuracy (for static channel ±2 feet at s.l.) Pressure resolution of 0.2 Pa.is also achievable. The intuitive user interface ensures that all the functions are controlled with a minimum of key presses. The ADTS can be used in avionics ATE systems for automated pitot-static testing through RS232 and/or GPIB/IEEE488. An internal or external rack mounted pump unit can be supplied as an option.

Pitot-static adaptors

A large variety of pitot-static adaptors can be supplied to interface Air Data Test Sets to aircraft and helicopters. The adaptors are supplied in a rugged waterproof case, complete with PVC pipes, red warning flags, pneumatic connections to ADTS, and in some instances with suction fixing pipe stands to aircraft static ports. A colour code allows the identification of the static or pitot ports connected, this feature is useful when using the Multiple Isolator Option available on our ADTS. Adaptors have a special design to safeguard the aircraft pitot static ports, which could be damaged if poor quality fixing devices are used.
