Mid-Continent Instruments a giant in the two-inch market

WICHITA, Kan. — Mid-Continent Instruments announces the TSO certification and delivery of the MD15 two-inch altimeter and the MD25 two-inch airspeed indicator.

“The MD15 altimeter and MD25 airspeed indicator complement our 4200 electric attitude indicator and complete the 2-inch standby package,” said Brett Williams, engineering manager for Mid-Continent Instruments. “Their small size saves space in crowded panels and provides either primary or standby instrumentation for any general aviation flight deck.”

The MD15 is a two-inch, three-pointer altimeter offered in a 20,000-ft. model, with a 35,000-ft. model to follow. Options include a barometric scale in inches of mercury or millibars and a left- or right-hand baro set knob. The instrument is FAA TSO-C10b certified.

The MD25 2-inch Airspeed Indicator is offered in multiple ranges: 160, 200, 260, 300, 350 and 400 knots. Range markings can be added to meet specific aircraft requirements. The instrument is FAA TSO-C2d certified for fixed-wing or rotorcraft operation.

Both instruments’ anti-reflective glass enhances visibility and reduces pilot fatigue. Units have a field-replaceable light-emitting diode (LED) or incandescent light tray available in 5, 14 and 28 VDC. The MD25 and MD15 are typically rear-mounted and can be installed individually or as part of a three-unit standby package — with the 4200 attitude indicator.

Tom Genovese, Mid-Continent Instruments’ director of sales, said, “There is a growing demand for smaller standby instruments in glass panel flight decks these days. The Mid-Continent standby package provides the time-proven information that pilots require without taking much panel space.”
