Aerosonic goes digital with standby indicators

Aerosonic Corp. of Clearwater, Fla., has received TSO approval from the FAA for its two-inch standby digital altimeter and airspeed indicators, on display in Booth No. 1217 along with the company’s line of vertical speed and cabin pressure indicators and clocks.

“Our mechanical instruments are excellent products, but mechanical instruments have limitations when compared with the reliability, accuracy and performance of digital instruments,” said Mark Perkins, Aerosonic executive v-p. The new digital altimeter and airspeed indicator significantly reduce lifecycle costs, he added. Both new products have 12,000-hour MTBFs at a list price very close to those of the Aerosonic mechanical instruments.

A supplier of mechanical and electromechanical cockpit instruments for the last five decades, Aerosonic scored with its new digital standby instruments when Cessna selected them for its Citation Mustang very light jet. They are also being flown in the Adam Aircraft A700 jet. The digital standby instrument is a “plug and play” design that interfaces seamlessly in older cockpits as well as with the latest EFIS displays, Aerosonic said. In addition, the precision of the digital instruments, with their highly accurate pressure transducers, matches that of glass displays, reducing squawks for discrepancies between the EFIS and round gauges.

Aerosonic operates manufacturing facilities in Clearwater and Charlottesville, Va. A customer support facility in Wichita handles repairs as well as aftermarket support.
