MIscellaneous Flashcards
Marginal Weather
Marginal weather exists when ceiling is within 100 feet and/or visibility is within 1/2 mile of destination published approach minimums or derived alternate weather minimums as appropriate.
Method 1
- One or more navigation aids, each providing a straight-in instrument approach
- Add 400 and 1 to any approach minimum
Method 2
- Two or more navigation aids, each providing straight-in approaches to different, suitable runways
- Find the two lowest approaches first
- Add 200 to the higher ceiling and 1/2 to the higher visibility of the two approach minimums
Thruflight Setup Check
- When on a subsequent flight, all of the following apply:
- Crew keeps the same aircraft
- Flight crewmembers remain the same, provided one flight crewmember remains on board
- Aircraft remains energized
- No maintenance action has been taken
Engine Start Abort Criteria
- No light-off within 10 seconds after the first fuel flow indications (on ground only)
- Fuel flow drops to zero PPH immediately after lightoff
- ITT rises rapidly toward start limit (hot start)
- ITT approaches start limit (hot start)
- N2 remains steady or decreases for more than 5 seconds (hung start)
- Any usual noise or vibration occurs
- Engine instruments indicate abnormal conditions
- Visible burning coming on the exhaust pipe
- Oil pressure does not reach at least 34 psi after the engine reaches stabilized idle
Limitations for ALT/TO
- Anti-skid must be operative
- ALT/TO may be used on wet runways, provided wet runway performance data is used
- Prohibited on slippery (wet ice) runways
- Prohibited if warnings of windshear or downdrafts are reported
- Prohibited when no ALT/TO performance data is provided for a runway with a Special Departure Procedure
Minimum Battery Temp & Voltage for APU Start
-20C & 23.5 Volts
Between 19 - 23.5 volts, APU must be started off ground cart
SG’s
Two IC-600 Symbol Generators (SGs).
The SGs interface work with many of the aircraft systems; they receive data from multiple inputs and send the appropriate information to the 5 CRT screens in the cockpit.
DAU’s
Data Acquisition Unit
DAU 1 is dedicated to collect data from the forward airplane systems and #1 engine.
DAU 2 is dedicated to collect data from the aft airplane systems and #2 engine.
RMU
Radio Management Units
EICAS
Engine Indication and Crew Alert System
AWU
Aural Warning Unit
Unsatisfactory Takeoff Warning Indication
- Flaps are not in a takeoff configuration (9, 18, 22)
- Parking brake is set
- Pitch trim is out of the green range
- Any spoiler panel is deployed
EGPWS
Enhanced Ground Proximity Warning System
SPS
Stall Protection System
DC Power System
- Four independent engine-driven generators
- One APU starter-generator
- Two Ni-Cad batteries
- One lead-acid backup battery
- External power receptacle
AC Power System
The main AC power source comes from a single-phase AC inverter, which converts 28 volt DC power into 115 AC.
EDL
Electrical Distribution Logic
When do the engine-driven generators come online?
56.4% N2
What happens when a T-Handle is pulled?
- The engine-driven hydraulic shut-off valve
- The fuel shutoff valve (located in the belly of the aircraft)
- Engine lip anti-ice valve
- Engine bleed valve
