Systems Flashcards
What mechanical systems assist the pilot with control of the helicopter?
SAS - Stability Augmentation System
FPS - Flight Path Stabilization
Boost Servos
Pitch, Roll, and Yaw Trim
From fore to aft, name the major mechanical systems above the cabin of the aircraft
What components make up the pilot assist servos?
Trim, Boost, SAS
Where are the pilot assist servos located?
From where is hydraulic pressure for the pilot assist servos supplied?
2 hydraulic system
What is the purpose of the Mechanical Mixing Unit?
- Combines, sums, and couples the cyclic, collective, and yaw inputs
- Provides proportional output through mechanical linkages, to the main and tail rotor controls
How many primary servos are there?
Where are the primary servos located?
3, between the #1/#2 hydraulic pumps
What systems connect the MMU to the tail?
How many hydraulic systems are there?
To what does the #1 hydraulic system supply power?
First stage of primary servos
First stage of tail rotor servo
To what does the #2 hydraulic system supply power?
Second stage of primary servos
Pilot assist servos
To what does the backup hydraulic system supply power?
1 or #2 hydraulic systems (for emergencies or ground checks)
Second stage of tail rotor servo
APU Accumulator
When do the #1/#2 hydraulic systems operate?
When the rotor blades are turning
How are the pedal brakes operated?
Applying pressure to the top part of both pedals
The droop stops should be full in during shutdown at what %NR?
50%
Fuel is suppled to the APU from which tank?
1
In a normal configuration, the HH60 can carry how much fuel, for how much flight time?
Approx 2400 lbs (360 gal)
Approx 2.2 hrs
How many different additional fuel tanks can be added?
2 or 4 External fuel tanks @ 200gal each
1 Internal fuel tank @ 195gal
Fuel cells can automatically self seal puncture by bullets up to what size?
7.62mm AP
What is the settling time for jet fuel?
Fuel samples are conducted how long after refueling?
1 foot / hr
At least 4 hours
T/F - The H60-M use the same generators on both a LAIRCM capable bird and non-capable bird?
False. LAIRCM capable birds require upgraded generators
T/F - Anti-icing systems will function with a (1) generator failure?
False. Anti-icing systems require two functioning generators
T/F - The hoist will function with a (1) generator failure?
False. The hoist requires two functioning generators.
What type of power do the generators supply for the aircraft?
115/200V AC, 400hz
For how long can the aircraft run on battery power if all generators fail?
15-30 minutes.
If a generator bearing warning appears, the bearing must be replaced in what time frame?
Within 10 hours of the caution appearing.
