Tachometers, Manifold Pressure Gauge, Airspeed Indicators

Airspeed Indicator The airspeed indicator is an instrument which senses the pressure generated by the moveement of air into the pitot tube, and the pressure (static) of the surrounding air mass. The difference in these two pressures causes the movement of a pointer over a dial marked in units of airspeed. The standard instrument carries an outer scale marked MPH and and inner scale marked KNOTS.


Dim: 3-1/8 x 3-3/8 x 2-1/8
Weight: .6 lbs approximately
Power: Pitot-static connections
Range: 40 to 180 MPH 40 to 160 KNOTS

Manifold pressure is one of the factors required to obtain correct power setting of the aircraft engine. Indicator is temperature and altitude compensated. Interchangeable with AN5770-1.
