DQ-132 Flashcards
The GTC−P36−150 APU failed due to low oil pressure. How would this be determined?
APU FAIL Caution light should illuminate.
Have to note and analyze BITE indication, to determine that it failed due to low oil pressure.
(3x white & 1x black - for one of three different type APU controller)
What is the purpose of the OAT and ice rate meter?
How is the ice detector turned on?
The OAT sensor, installed below the windshield, provides a signal to the controller for heating EOT (Element ON Time) of the rotor blades. The lower the OAT, the longer EOT will be. In AUTO (automatic), the ice rate signal is passed on to the controller, which results in off-time variations proportional to the ice rate. In MANUAL, T, L, or M, fixed signals are transmitted to the controller, resulting in fixed element-off-time.
The ice rate meter or DCIU provides a visual display of icing intensity (T (trace), L (light) blue for ice rate meter, green for DCIU, M (moderate) yellow, and H (heavy) red).
The ice rate meter activates the ICE DETECTED caution when the BLADE DE-ICE POWER switch is off.
The ice detector is operational anytime power is applied to the helicopter.
Why should the windshield wipers not be operated on a dry windshield?
Why should the wipers be parked if they slow noticeably?
Caution - To prevent possible damage to windshield surface, do not operate windshield wipers on a dry windshield.
Wipers must be parked to avoid wiper motor failure.
Forplanning, how much fuel would be required for run-up assuming 15 minutes on the APU, 10 minutes at idle, and 10 minutes at 100% RPM R (0 PA)?
15 min APU 120 lbs/h. = 30 lbs
10 min IDLE (0´ PA) 360 lbs/h. = 60
10 min 100% RPM R 590 lbs/h. = 100
Total = 190 lbs
Given the following cruise conditions what is the Maximum Endurance and Maximum Range IAS and explain how is it calculated?
TEMP 40 Degrees
PA 2000’
ACFT GWT 20000 LBS
Max Rng: 130 KIAS
Max End: 73 KIAS
Intercept GWT with MAX RNG & END -> Read IAS

What is an unnecessary risk?
What criteria do Army leaders use to determine an acceptable risk?
An unnecessary risk is any risk that, if taken, will not contribute meaningfully to mission accomplishment or will needlessly endanger lives or resources.
Commanders applies Risk Management to weight potential gain vs loss. Commanders should only accept a level of risk in which the potential benefit outweighs the potential loss.
