Flashcards in Systems Deck (19)
Excessive windshear of the current position detected.
Enabled below 1500 feet RA.
GPWS Windshear detection begins at rotation.
Detected by the weather radar.
Enabled during takeoff below 1200 feet. (Triggered when thrust levers set for Takeoff)
Inhabit above 100knt.
Go around windshear Ahead
Within 1.5 miles and directly ahead of the airplane detected by the weather radar.
Enabled during approach below 1200 feet ( weather radar start scanning below 2300 feet RA).
Monitor radar display
Windshear within 3 miles and a head of the airplane detected by the weather radar.
Enabled during takeoff and approach below 1200 feet RA.
The FMC transitions out of “on approach”
• selecting TO/GA
• the airplane lands
• the waypoint cycles to the first waypoint of the missed approach
• executing a direct-to waypoint in the missed approach.
Below 2000 feet radio altitude, the FMC transitions to go-around logic from
approach logic when any of the following events occur
• pushing either TO/GA switch while in a descent
• executing a direct-to waypoint in the missed approach (other than the missed approach point)
• automatically while in a descent and the last waypoint of the approach cycles to the first waypoint of the missed approach.
• the airplane climbs at a vertical speed greater than 600 fpm and the flaps
are retracted from a landing setting toward a flap setting of 15 or 1
Note: LNAV may be engaged when the airplane climbs above 400 feet radio altitude, but VNAV should not be engaged until after flap retraction. FCOM 11.31.38
Drift Down Execution
• disconnect A/T
• set maximum continuous thrust on operating engine (N1 line)
• set MCP speed to ENG OUT SPD
• set MCP altitude to MAX ALT or lower altitude as required
• At ENG OUT SPF select LVL CHG.

Radio altitude based alerts
Excessive decent rate - SINK RATE
Excessive terrain closure - TERRAIN
Altitude loss after take off or go around - DON'T SINK
Unsafe terrain clearance not in landing configuration - PULL UP
Excessive deviation below ILS G/S - GLIDESLOPE
TOO LOW FLAPS
TOO LOW GEAR
Look ahead Terrain alerts
TERRAIN TERRAIN PULL UP
20-30 seconds, terrain solid red on ND
30-40 seconds, terrain solid Amber on ND
TOO LOW TERRAIN
below unsafe RA, to far from any airport in data base
Graphical representation of surrounding terrain on the ND
• Dotted red: Terrain more than 2,000 feet above airplane altitude
• Dotted amber: Terrain 500 feet (250 feet with gear down) below to 2,000 feet above the airplane’s current altitude
• Dotted green: Terrain from 2,000 feet below to 500 feet (250 feet
with gear down) below the airplane’s current altitude
• Dotted magenta: No terrain data available

Landing gear indications
Up-10: if thrust levers less then 20/34. Can be switched silenced but not below 200RA.
15-25: if thrust levers less then 20/34. Can't be switched silenced.
>25: can be silenced only when configuration error is corrected.
