HIT Baseline/Max Power/Auto Flashcards
The HIT Check assists in identifying significant performance shifts, engine performance trends, and verifies _________.
The HIT Check assists in identifying significant performance shifts, engine performance trends, and verifies proper operation of the engine Anti-ice Start Bleed Valve and inlet anti-ice valve.
During the Operational HIT Check, if the TRQ indication of the engine not being checked is greater than 5% at 92%–98% Np, this is an indication of _______.
During the Operational HIT Check, a TRQ indication of the engine not being checked, greater than 5% at 92% - 98% Np is an indication of Torque Stiction.
The AIR SOURCE HEAT/START switch has been set to ENG, but the TGT rise is 7°. What is the probable cause?
If the TGT rise is greater than 5 degrees when the AIR SOURCE HEAT/START switch has been set to ENG, the probable cause is a pneumatic system leak.
The engine being checked has had the ENG ANTI-ICE switch placed in the ON position. What is the importance of a least a 30 degree rise, but less than a 110 degree rise in that engines TGT?
With the ENG ANTI-ICE switch placed in the on position of the engine being checked, if the TGT rise is greater than 30°, and more than 110°, you are checking for a faulty Engine Anti-Ice Start Bleed Valve or Inlet Anti-ice Valve.
Cycling the Anti-Ice Bleed and Start valve more than once will create the wrong fuel to air mixture and __________.
Cycling the Anti-Ice Bleed and Start Valve more than once will create the wrong fuel to air mixture and steal bleed air from the compressor.
According to the Design Specifications, the Barometric Altimeter setting used to establish the engine performance data is _______.
According to the Design Specifications, the Barometric Altimeter setting used to establish the engine performance data is 29.92.
The _______ provides an accurate indication of available power by incorporating ambient temperature effects on degraded engine performance.
The Torque Factor Method provides an accurate indication of available power by incorporating ambient temperature effects on degraded engine performance.
The effect of cold free air temperatures and high air density is the explanation for what?
The effect of cold free air temperatures and high air density is the explanation for Overstated Power.
A Maximum Power Check is required when an engine fails a HIT Check, during a general test flight, and _______.
A Maximum Power Check is required when an engine fails a HIT Check, during a general test flight, and after engine installation or reinstallation.
During an Autorotational RPM check observed RPM-R must be?
During an Autorotational RPM check observed RPM-R must be within + or - 3% of target RPM-R.
During an Autorotational RPM check a power recovery must be completed by _______?
During an Autorotational RPM check a power recovery must be completed by 500’ AGL.
To adjust Autorotation RPM R you _______?
Adjust all 4 PC rods equally in the same directions to adjust Autorotation RPM R.
