15.21 operation and monitoring Flashcards
what happens when the thrust lever is moved away from the idle position
it causes the fuel control system to supply more fuel as the engine speed increases
what is provide on engines equipped with thrust reversers
a separate fuel shutoff lever
Before any engine start, a check of the engine air inlet is needed to confirm what
there is free movement of the compressor and turbine assembly
what position must the aircraft be in, in relation to the wind
The aircraft must be positioned into the wind
when is cool-down time for the engine allowed
before shutting down the engine
what is the data recording on board the aircraft preformed by
the Aircraft Condition Monitoring System (ACMS).
Engines with hydro-mechanical fuel controls need an additional computer for the parameter measurement, what is it called
Power Plant Data Multiplexer (PMUX).
what are the two types of analysis done on an aircraft called
thermodynamic
mechanical-dynamic
when are the ACMS take-off reports are generated
during the first four flights
after a while, a take-off report is generated after how many take offs
every 35 take offs
what is one of the easiest ways of identifying different materials
by the use of chemicals
what provides indication of the internal condition of the engine and gearbox.
A visual inspection of Magnetic Chip Detectors (MCD)
what kind of damage does boroscope inspections identify
internal damage
must must all repairs be well blended on blades
so that the surfaces are smooth
how must rework on a blade be carried out
by hand, using files, or emery cloth
If the major cause of contamination is salt ingestion, what is scheduled
a rinsing of the compressor with fresh water
If the wash is being carried out in low-temperature conditions with water, ensure only is used as an anti-ice
isopropyl alcohol
what can Ingestion of foreign matter into the intake of a turbine engine cause
detrimental damage and degrade engine performance
