Systems

Question 1

Windshear Ahead

Answer 1

Detected by the weather radar.
Enabled during takeoff below 1200 feet. (Triggered when thrust levers set for Takeoff)
Inhabit above 100knt.

Question 2

Go around windshear Ahead

Answer 2

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).

Question 3

Monitor radar display

Answer 3

Windshear within 3 miles and a head of the airplane detected by the weather radar.
Enabled during takeoff and approach below 1200 feet RA.

Question 4

The FMC transitions out of “on approach”

Answer 4

• 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.

Question 5

Below 2000 feet radio altitude, the FMC transitions to go-around logic from
approach logic when any of the following events occur

Answer 5

• 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

Question 6

Drift Down Execution

Answer 6

• disconnect A/T

S/B not down 
S/B not retracted when lever is down 
Parking brake set
STAB TRIM Norit in the green band.

Question 10

GPWS warnings

Radio altitude based alerts

Answer 10

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

Question 11

Look ahead Terrain alerts

Answer 11

TERRAIN TERRAIN PULL UP
20-30 seconds, terrain solid red on ND

CAUTION TERRAIN
30-40 seconds, terrain solid Amber on ND

TOO LOW TERRAIN
below unsafe RA, to far from any airport in data base

Question 12

Graphical representation of surrounding terrain on the ND

Answer 12

• 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

Question 13

Hydraulic system A&B clients

Answer 13

A: flight controllers, flight spoilers (2 each wing), ground spoilers, alternate breaks, A/P A, #1 thrust reverser, normal nose wheel steering, landing gear, PTU.

B: flight controllers, flight spoilers (2 each wing), LE&TE flaps/slats, normal breaks, #2 thrust reverser, alternate nose wheel steering, yaw damper,

Question 14

SBY Hydraulic system

Answer 14

sby yaw damper, sby rudder pcu, rudder, LE flaps and slats, thrust reverser

Question 15

Landing gear indications

Answer 15

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.

Question 16

PSEU

Answer 16

Takeoff and landing configuration warnings.
Landing gear.
Air/Ground sensing
Wing emergency doors lock.

Question 17

What’s available on battery power

Answer 17

Pressurization - MAN
Left side flight instruments 
No fuel pumps 
No PITOT HEAT (most airplanes)
No flap position indication
No Radio Altimeter readouts
No electrical trim

Question 18

Do not reengage engine starts swhich below

Answer 18

20% N2

Question 19

Windshear warning

Answer 19

Excessive windshear of the current position detected.
Enabled below 1500 feet RA.
GPWS Windshear detection begins at rotation.

Question 20

DUCT PRESS indicator shows 0 without any further indications

Answer 20

Crew action based on the pneumatic duct pressure indicator is not required.

Question 21

engine failure will cause the “Secondary” engine display to “Pop-Up” on the Lower Center DU even if the “Compact” engine display is displayed on the Upper Center DU?

Answer 21

If the secondary engine information is being displayed, such as in compact form on the upper center DU, then the secondary engine display will not pop up on another display.

Question 22

Transponder Mode ON or AUTO?

Answer 22

On unless specified AUTO by airport regulations

EFOS Technical Boeing answer

Question 23

2 basic principles of operation for the 737 electrical system

Answer 23

There is no paralleling of the AC sources of power.

• The source of power being connected to a transfer bus automatically disconnects an existing source.

Question 24

Engine tailpipe fire FCTM

Answer 24

• to prevent an inappropriate evacuation, flight attendants should be notified without significant delay

Question 25

Loss of engine control. Which QRH?

Answer 25

Engine limit surge or stall

Fctm

Question 26

Speed trim system (Sts)

Answer 26

improve flight characteristics during operations with a low gross weight, aft center of gravity and high thrust when the autopilot is not engaged.

Question 27

Mach trim system

Answer 27

provides speed stability at the higher Mach numbers. Mach trim is automatically accomplished above Mach .615 by adjusting the elevators with respect to the stabilizer as speed increases

Question 28

Stab trim override switch on pedestal

Answer 28

When the STAB TRIM override switch is positioned to OVERRIDE, electric trim can be used regardless of control column position.
See jammed or restricted flight controls

Question 29

PTU

Answer 29

Supply additional volume of hyd fluid needed to operate autoslats and leading edge flaps and slats at the Normal rate when sys B engine driven pump volume is lost.

Uses sys A pressure to power a hyd motor driven pump which pressurized sys B Hydraulic fluid

Question 30

Autoslats

Answer 30

Powered by sys B.
Alternate source sys A via PTU.
Flaps 1,2,5- LE slats move to full extend if the airplane approaches a stall condition.

Question 31

Ldg gear transfer unit

Answer 31

Supply volume of hydraulic fluid needed to raise the ldg gear at normal rate when sys A engine driven pump volume is lost.
Sys B eng driven pump supplies the volume of hydraulic fluid needed to operate the landing gear transfer unit when all of the following exist:
Airborne
No.1 engine RPM drops below limit value
Ldg gear lever is UP
Either main landing gear is not up and locked.
