label in Inverse Video - How is a miscompare annuciated on the EICAS display?
SAS, Trim, FPS, Stabilator, Flight Director - What are the five AFCS subsystems?
Collective, Pitch, Roll, & Yaw - What axis does Trim operate in?
Pitch, Roll, & Yaw - What axis does SAS operate in?
Vertical Accelerometer - What component senses the aircrafts vertical acceleration?
SAS; Trim & FPS - Inner loop refers to what system? Outer loop?
Stabilator Actuators - Each FCC receives signals from the pilot flight controls, motion
sensors, control panels,
and avionics systems to compute commands which are sent to the cockpit, trim
actuators, SAS actuators, and _____________________.
pitch, roll - The FCCs, through FCC 2, provide FPS command signals to the pitch, roll
and yaw trim actuators which in turn reposition the flight controls for ________ &
________ attitude hold and also heading hold in yaw.
Rate Gyros - On the UH-60M, AFCS _____________ have been replaced with EGI's,
lateral, longitudinal, and vertical accelerometers.
Flight Director - AFCS is comprised of five basic subsystems: Stability Augmentation
System (SAS),
Trim, Flight Path Stabilization (FPS), _________________, and Stabilator.
22, 13, & 80 lbs - What are the forces required to break through a jammed collective,
roll, and yaw trim actuator?
SAS - The _____ system enhances turn coordination.
SAS OFF Caution - What is the indication for loss of pressure at the SAS Actuators?
Air Data Computers (ADCs) - The stabilator system utilizes airspeed signals that
originates from where?
Embedded GPS Inertial Navigation Systems (EGIs) - The stabilator system utilizes pitch
rate signals that originates from where?
The stabilator being unlocked and/or folded - The STAB UNLOCKED indication is
caused by?
, Collective Stick Position signal, Lateral Accelerometer signal, Pitch Rate signal - The
STAB DEGRADED advisory will appear due to the loss of, or an invalid
________________________, _____________________, or ____________________.
Airspeed - An Air Data Computer miscompare or loss of the _________ signal will result
in the STAB MANUAL MODE Caution?
On the ground with Nr < 10% - The Stabilator test can only be performed when the
helicopter is ____________________.
Vne (red arc) - What provides a visual Vne indication?
Limited Auto Mode - It is possible for the STAB DEGRADED advisory indication to
appear on the EICAS
display when an actuator physically fails to program as commanded. As long as the
FCC
can identify the position of the failed actuator, the other FCC will continue to program its
actuator automatically, but in a ______________________.
STAB UNLOCKED - The 3-piece stabilator is also equipped with locking mechanical
pins and Lock Pin Position Switches. The switches are wired in series and provide an
indication of the stabilator condition. A _________________ caution will be displayed if
unlocked.
Stabilator Actuators - Two identical _____________, mounted back to back and located
in the tail pylon assembly are used to position the stabilator.
Power Pod - TGT will be indicated on the _____________ when TGT indications are
above the normal operating range (above 793°C).
Upgraded - The Engine Output Shaft /High Speed Shaft connection to the Input Module
has been ___________ to a new configuration.
UES - The ____________ provides added protection from heat-seeking weapons'
systems by mixing hot exhaust with outside ambient air.
More power - Compared to the 700 and 701C engine, the 701D engine provides
_________________.
HMU - The acceleration and Variable Geometry 3D cam within the ______ has been
changed to improve the engines acceleration schedule in high altitude, hot day
conditions.
No - Does the UES have any moving parts?
