Abstract :
The Air Speed Indicator is one of the important flight instruments in an
aircraft, in addition to the Altimeter (altitude indicator), Rate-of-Climb Indicator
(speed upward), and manifold pressure indicator. Even though air is very light, it
has mass and is affected by the force of gravity.
Failure occurs when the indicator has an error, resulting in an error in the
mach airspeed warning system not sounding and causing no bugs.
The results obtained after carrying out the test, the indicated numbers on
the indicators are appropriate and the bugs have reappeared on the indicators, so it
can be concluded that the problem has been resolved and the aircraft is back
serviceable
