AIRPLANE DESCRIPTION
7.12.2 MECHANICAL AIRSPEED INDICATOR ( ASI )
The airspeed indicator (ASI) is TSO'd and is regarded as a primary flight in-
strument and located on the pilot’s instrument panel. The instrument senses
di ff erence in static and Pitot pressures and displays the result in knots on an
airspeed scale. It's a mechanical instrument and does not require electrical
power to function.
7.12.3 MECHANICAL ALTIMETER ( ALT )
The altimeter (ALT) is TSO'd and is regarded as a primary flight instrument.
Airplane altitude is depicted on a conventional, three-point, barometric al-
timeter. The instrument senses the local barometric pressure adjusted for al-
timeter setting and displays the result on the instrument in feet and does not
require electrical power to function. Barometric windows on the instrument’s
face allow barometric calibrations in either inches of mercury (inHg) or milli-
bars (mb). The barometric altimeter settings are input through the barometric
adjustment knob at the lower left of the instrument.
7.12.4 MAGNETIC COMPASS
A conventional, liquid filled magnetic compass is installed on the metal
frame above the instrument panel. A compass correction card is installed
with the compass.
7.12.5 RPM/POWER INDICATOR
The RPM/power indicator is s 57 mm (2 ¼ ”) unit which displays the current
RPM with both a familiar mechanical needle as well as a large OLED digital
display. Motor power is also indicated on the display. Digit colors are white,
but turn yellow or red when parameters are in caution or warning range. The
information is also available on the EPSI570C display as primary info.
7.12.6 VERTICAL SPEED INDICATOR ( VSI )
The variometer is a 57 mm (2 ¼ ”) unit and consists of a familiar needle and
OLED digital display. The needle shows if the aircraft is climbing or descend-
ing.
