FOR SIMULATION PURPOSES ONLY
Vertical Speed Indicator
The VSI is marked to indicate rates of climb and descent between 0 and 2000
fpm on a scale graduated at intervals of 100 fpm.
Mechanical stops are incorporated to prevent the indicator needle passing
the 2000 fpm indication.
Attitude Indicator
The AIs on each side of the instrument panel are AIM 1100 or Mikrotechna
LUN 1241 series electrically driven instruments powered from separate
busbars.
The primary instrument, the starboard AI, is powered from the Essential busbar
and the other, the alternate instrument, is powered from the Avionics II
busbar. Each gyroscope is connected to a blind marked with a horizon line
and lines representing pitch values of 5°, 10°, 15° and 20° of climb and dive.
A warning flag is incorporated which is displayed when power to the
instrument has failed, the rotor speed is too low, or the pull for quick erect
knob is used.
