Eaws 2nd Book Flashcards
Aircraft safety areas (airframes)
Safety diamond, safety pins, floor panels, outside observer prior to operating flight controls
Safety diamond
5ft extending out of aircraft
The p3 is of __________ construction with the exception of the radomes and wingtips
All metal construction
Corrosion prone areas of p3
Along the seams of aluminum alloy structures, box beam areas and around steel fasteners. Unpainted surfaces of actuating mechanisms, chipped paint surfaces, skin seams and areas where dirt and grime collect
Wings
Center wing is an integral part of fuselage.
Outer consists of flaps, wing tips, ailerons, nacelles and leading/trailing edge
Wing flaps
High lift fowler type powered by hydraulics.
Horizontal stabilizer
Longitudinal stability- elevators attached. Stability about lateral axis
Vertical stabilizer
Directional stability- stability about vertical axis. Rudder is attached
Rudder
Move aircraft about vertical axis. Right equals right
Ailerons
Opposite direction to one another. Controlled movement of a roll because of unequal forces on wings
Elevators
Control stick. Climb or descend
Autopilot
Control and stabilize about roll pitch and yaw
Landing gear
Dual wheels and forward retracting struts. The weight of the AC on the gear keeps it down and locked
Struts
Absorbs shock
Brakes
Multi disk hydraulic powered brakes. Nose has no brakes
Parking brake
Brake accumulator will keep the brakes set for 30 hours
Wheels
Dual wheels mounted on each strut
P3 access points
5 with 2added cut outs
Powerplants hazard areas
Prop area, jet blast area and anti-collision light on top of aircraft should be flashing with engines running on deck
P3 engine
Four T56-A-14 turboprop power plant assemblies. Independent engine power lever system for pilot and copilot
Propellers
A variable pitch, constant speed and hydromatic prop assembly is mounted on each assembly. 4 blades. “Feather” minimizes drag
Fuel tanks
Aux is number 5. Wing is 1-4. Fuel is normally supplied from 2
Fueling
Center point pressure. If not available, overwing fueling
Total fuel capacity
9200 gallons
Bleed air
Heated and pressurized air from compressor for bomb bay heating, engine anti ice, wing de ice, etc. all weather capable
APU
Compressor, gas turbine engine, engine driven electrical generator.
Hydraulics safety
Extreme caution under pressure to avoid injection Into skin, if so seek medical. Cooled through 2-3 . Minimum of 1000 pounds for cooling
Pascals law
Pressure exerted anywhere upon enclosed liquid is transmitted undiminished in all directions
Hydraulic pumps
3 AC and 1DC
Reservoirs
1has 5.6 gallons
2has 1gallon
Booster assembly
So pilot has normal feel of control forces when hydraulic pressure available to cylinders.m
Actuators
Transform hyd fluid pressure into mechanical force to perform work
Voltage
Current to flow in circuit (V)
Electrical current
Through circuit (amps)
Resistance
Opposition in ohms
Hertz
One cycle per second in hertz
Bus
Distribution point where battery and generator are connected
AC generator
234 engines at reduction gear drive. GEN OFF light indicates failure
APU AC generator
Identical plus cooling bell housing
Distribution
Sending relays; connect and control power to buses. Located in main and forward load centers
Battery
24 volt
Circuit breakers
Protect systems
Electro optics
Irds turret
Sasp
Single advanced signal processor
Mad
Magnetic anomaly detection
Esm
Electronic support measures; detects and analyzes radar signals and gives direction. Ss3 can then identify type of ship or aircraft
Otpi
Bearing to bouy
DPS
Data processing system; interfaces all systems for control
