GK Flashcards
Fuel System
Fuel tank Gascolator Dukes fuel pump or bypass Fuel shutoff valve Engine driven pump (& swirl chamber) Throttle body Fuel distribution manifold Fuel injector nozzles Engine cylinders
24.0 gal
6 gal/hr burn rate
Day=+30, night=+45
6lbs/gal, 100LL (blue color)
Night ops aircraft lighting
Position lights: Red on left wing tip; green on right wing tip; white on tail
Anti-collision lights: Flashing or rotating beacon and position lights
Strobe lights: On wingtips; flash from takeoff to landing
VOR/GPS Navigstion
GPS uses satellite
VOR uses signal from station
Oil system
Wet oil sump Engine driven oil pump Oil filter Vernatherm or bypass to oil cooler Engine accessories (crank, rod, piston, bearing) Cylinders & components
Cleaning, cooling, reduce friction
Lost procedures
Climb: See land marks or gain GPS/VOR signal Conserve: Save fuel: 73 kts flaps cruise Confess: SOF, ATC, FSS
Wind shear
A sudden drastic change in wind speed and or direction over a very small area. Windshear can subject and aircraft a violent updrafts and downdrafts low level associated with passing frontal systems thunderstorms and temperatures with strong upper-level winds (greater than 25 kn)
Clock to map to ground method
Navigate by looking at the clock then to the map then to the ground and adjust accordingly.
METAR
An aviation routine weather report that is an observation of current surface weather report in a standard international format.
Provide info on current conditions for specific airport out to a radius of five statute miles reported in the vicinity is between 5 to 10 miles and reporting station.
ATC clearances & Instructions
ATC clearance-authorization to proceed under specific traffic conditions and controlled airspace
No pilot in command may deviate from that clearance unless:
- Amended clearance is obtained
- Emergency exists
- Deviation is in response to a traffic alert & collision avoidance system resolution advisory
ATC clearances are not authorization to deviate from the rules.
Pitot Static System
Pitot static probe Airspeed indicator (p/s) Altimeter (s) Vertical speed indicator (s) Blind altitude encoder (s) Mode C transponder (s) HOBBS meter (s)
TAF
Always produced by a human forecaster. TAF locations are far fewer than METAR locations. Established for the 5 statue mile radius around the airport.
DA20 glide performance
11:1 glide ratio
1.8 for 1000 ft of altitude
Add 1/2 of any headwind component to your airspeed.
Subtract 1/4 of tailwind component to your airspeed
Retracting the flaps from LDG to T/O or CRUISE at low altitudes is not recommended b/c it can cause rapid & unexpected sink.
Traffic pattern procedures
Civilian vs military pattern
3000 ft lateral spacing min TPA is from 600 ft to 1500 ft AGL
L pattern is standard
Closed turn criteria:
1) beyond the departure end of the runway
2) after climb checklist
3) within 300 ft of the traffic pattern altitude
4) traffic spacing is sufficient
Wake turbulence avoidance
3 min: large/heavy
2 min: small-plus
1 min: small helicopters
300ft: large rotary wing aircraft
200ft: small-plus helicopters
100ft : small helicopters
Night ops airport lighting
Visual glideslope indicators:
Visual approach slope indicator
Precision approach path indicator
Airport beacons:
Civilian land-alternate white & green
Civilian water-alternate white & yellow
Military-alternate two white one green
Runway lighting:
White lights on the edges of the runway; green on; red on it
Taxiway lighting:
Blue lights on edge of taxiway
Green lights on center
MOAs
Airspace of defined vertical and lateral limits established for the purpose of separating military training activity from IFR traffic. No VFR restriction in MOAs. Exercise extreme caution
