RVSM Digital Air Data Testers
DPS350
Digital Air Data Tester
The Barfield DPS350 Air Data Tester is a microprocessor-based unit using the latest in transducer technology. The DPS350 operates similar to Barfield’s 1811 series testers but the transducer technology used is virtually immune to the costly repairs generally experienced by analog instruments. Software containing a programmable protection limit feature has been incorporated into the DPS350 to insulate the aircraft instruments from damage caused by negative airspeed and over pressurization conditions. Limit protection is provided by computer actuated solenoid valves that safeguard aircraft altitude, airspeed, rate of climb/decent and mach instruments.
The high accuracy and a stability exhibited by the transducers qualifies the DPS350 for use on aircraft being certified for Reduced Vertical Separation Minimum (RVSM) operation and increases the calibration interval from 30 days to once a year. The simple menu driven digital display calculates and dis-plays Altitude, Vertical Speed, Airspeed, EPR and other measurements in various units of measure, including: Ft, M, Kts, Km/hr, Mach, Ft/min, M/min, EPR (Pt/Ps), inHg, mb, and psia. The tester also includes internal pumps that can produce a pressure and vacuum suitable for simulating 55K Ft, 650 Knots, and 6000 Ft/min conditions in wide body aircraft.
In addition to the industry’s leading Pitot-Static/Air Data testers, BARFIELD also offers the entire NAVAIDS product line of custom Pitot and Static adapters for most Military, Helicopter, General Aviation Aircraft, Corporate Jets, and Airliners.
DPS400
Digital Air Data Tester
The DPS400 is a microprocessor based unit using the latest in transducer technology. These transducers combined with manually controlled ultra sensitive differential regulators enable a technician to precisely control the altitude and airspeed without the need for correction cards. These true differential regulators enable a technician to independently control the airspeed and altitude and remove the need for a crossbleed valve.
The accuracy and stability qualifies the DPS400 for use on aircraft being certified for Reduced Vertical Separation Minimum (RVSM) operation and increases the calibration interval from 30 days to once a year. The simple menu driven digital display calculates and displays Altitude, Vertical Speed, Airspeed, EPR and other measurements in various units of measure, including: Ft, M, Kts, Km/hr, Mach, Ft/ min, M/min, EPR (Pt/Ps), inHg, mb, and psia. Software containing a programmable protection limit feature has been incorporated into the DPS400 to protect the aircraft instruments from damage due to negative airspeed and over pressurization conditions. Limit protection is provided by computer actuated solenoid valves that safeguard aircraft altitude, airspeed, rate of climb/decent and mach instruments. The tester also includes internal pumps that can produce a pressure and vacuum suitable for simulating 55K Ft, 650 Knots, and 6000 Ft/min conditions in wide body aircraft.
In addition to the industry’s leading Pitot-Static/Air Data testers, Aero Express offers NAV-AIDS product line of custom Pitot and Static adapters for most Military, Helicopter, General Aviation Aircraft, Corporate Jets, and Airliners.
DPS450
Digital Air Data Tester
The new DPS450 completes an entire line of Barfield Digital Pitot-Static/Air Data testers. Designed to minimize aircraft downtime, the DPS450 is the newest and one of the lowest cost fully automated Air Data Testers meeting the high accuracy demands of Reduced Vertical Separation Minimum (RVSM) specifications on the market.
All functions of the tester are fully automatic and require no manual sequencing of valves or regulators. The DPS450 has fully automatic control by means of the menu-driven high contrast electroluminescent display and tactile membrane keypad. The automated controller automatically generates and continuously maintains the input altitude, airspeed or VSI values. The DPS450 precisely maintains the input value (Ps, PT, Airspeed, Alt, etc.) overcoming any pressure values caused by a leaky system. A precision vibrating element sensor on the static channel provides high accuracy altitude measurement and simulation. This high accuracy and stability qualifies the DPS450 for certifying aircraft for RVSM operation and increases the calibration interval from 30 days to once every year.
The sophisticated yet user friendly display is fully programmable for a range of test requirements. It can be configured, with limits and referred units of measurement, for individual aircraft types. The level of information displayed can be determined by the operator to suit the particular task at hand.
In addition to the standard pitot-static functions of the DPS450, there are many additional advanced features that include: automatic go-to-ground, leak test mode and device under test protection amongst others. This enables the operator to undertake flightline testing accurately and efficiently, without compromising safety standards.
To complement the industry’s leading Pitot-Static/Air Data testers, Aero Express also offers the NAV-AIDS product line of custom Pitot and Static adapters for most Military, Helicopter, General Aviation Aircraft, Corporate Jets, and Airliners.
DPS500
Digital Air Data Tester
The DPS501 is a rack mountable Dual Channel Controller ideal for use as a transfer standard for calibration and certification of altimeters, airspeed ind., Air Data Computers, VSI and other Pitot-Static components or as an integral part of an Automatic Test Equipment (ATE) system.
The DPS500 Air Data Test Set (pictured) is a selfcontained, transportable, fully automated, user programmable Pitot-Static tester housed in a military styled enclosure. The unit includes a DPS501 controller, a Pressure/Vacuum pump, and a remote hand-terminal permitting convenient operation from the cockpit.
The DPS500 flightline version and the DPS501 rack mount version are fully automated units capable of providing simulation, testing, and precision calibration of air data components on the flightline or in a certified repair shop. All functions of the testers are fully automatic and require no manual sequencing of valves or regulators. The DPS500/501 testers were developed to meet the aviation industry’s increasing standards and the need for reducing maintenance costs. Precision Vibrating element sensors achieve high accuracy read-out and control of both altitude and airspeed parameters. The high accuracy and stability (see Air Data Specifications pages 13-14 for details) of the unit qualifies the DPS500/501 for certifying aircraft for Reduced Vertical Separation Minimum (RVSM) operation and increases the calibration interval from 30 days to once every year.
An optional Test Program Manager interfaces the DPS500/501 with a PC/Notebook allowing the execution of procedures for carrying out tests such as FAR 43 Appendix E, FAR 91-411, RVSM or other user programmed test routines. These user-programmed tests are created in a PC based text editor using very simple commands. Test data is tabulated and can be printed for use in QC reports or instrument calibration records.
