AQP Flashcards
Low Visibility Take-Off us less than 1 mile- what happens:
- Captain does take-off
- Check 10-9- make sure it is legal take-off from this airport
- Take-off alternate needed.
- No checklist while moving
- Static take-off
Sim world- heard “vectors”
Go to HDG mode
Flaps8, bug 200
Sim- “Maintain 3000”
I say “Set my next altitude”
Auto pilot automatically disengages during:
AP/SP DISC button pushed AP ENG button on FCP pushed AP disc switch bar pushed down Stick shaker activated TOGA buttons pressed STAB TRIM manually operated Wind shear warning (after 2 seconds) Excessive altitude One or both FCCs fail Both yaw dampers disc or fail
Stall warning??? System manual
SYNC switch
On control wheel- allows FD command bars to synchronized with the actual vertical and lateral reference when autopilot is disengaged
In a power failure - how are the Primary flight controls powered?(rudder, ailerons, elevator)
Hydraulic Pump 3B-which is electrically energized by the ADG
What are the Secondary Flight controls
Horizontal stabilizer trim
Slats/flaps
Multi-function spoilers
Ground spoilers
Aileron and rudder trim
What does the D.C. SERVICE switch power?
- Lights (NAV, beacon, service,boarding, toilet and galley dome)
- Boarding announcement
- Cabin lighting, upward and downward
- Service bus feed
- Power sensing (Service bus and TRU)
- Chart holder
- Water and waste control
What lights illuminate with BATTERY MASTER ON ( NO AC power established)
- The AC ESS XFER switch light
- INOP portion of L and R boost pump switches
- Fault portion of the PRESS CONT switchlight
- OFF portion of the L and R PACK switch lights
- MACH trim switch light
What is Mach number
Ratio of aircraft’s airspeed to the speed of sound.
.8 Mach- aircraft traveling at 80 percent of speed of sound
Air is compressible and at high air speeds- there are big density changes
When you go faster, the air molecules “pile up” in front and can not get out the way fast enough- increasing pressure, density and temperature in that region.
As plane enters transonic speeds, the air going over parts of the wing are supersonic, resulting in a sudden tremendous increase in air density as air piles up in front of the plane.
Mach trim
Once plane travels faster than the speed of sound, it is moving faster than the air molecules can get out-of-the-way. A Powerful compression or shock wave forms at the boundary between the disturbed and undisturbed air forms.
The faster the plane goes the further back on the wing the shockwave moves.“. The shock wave causes airflow separation toward the trailing edge of the wing. This disturbed air ultimately begins to affect the horizontal stabilizer, causing a high-speed buffet similar in feel to a stall buffet. A high-speed buffet may be encountered at different Mach numbers depending on altitude, load factor, and the weight of the plane.
“Mach tuck develops because a wing’s net center of pressure moves aft as its speed approaches the sound barrier. The farther aft the center of pressure moves the greater the pitch-down moment generated by the wing. The problem may then compound; as the aircraft pitches down, its airspeed continues to climb, increasing the effects of the shock wave and thereby worsening the Mach tuck effect. Left uncorrected, the aircraft may increase its pitch-down tendency and continue to accelerate until airframe failure.
Recovering from Mach tuck requires slowing the aircraft, either by throttle reduction, pitch change, or increasing drag. This is not necessarily as easy as it sounds. Airload on the tail under such circumstances can reach the point where there’s not enough pitch authority for recovery. Accordingly, many aircraft are equipped with protective Mach trim compensators. These devices track airspeed and, if the onset of Mach tuck is projected, automatically apply up-elevator to slow the aircraft and avoid the encounter.
Significant deviations as defined by current CFM
(3) Significant deviations are defined as:
(a) Airspeed + 10 KTS.
(b) Altitude + 100 feet.
(c) Heading + 10°.
(d) Vertical Speed + 250 fpm from target rate.
(e) Course 1 dot.
(f) Glideslope 1 dot above, 1/2 dot below.
(g) Bank Angle exceeding 30° or + 5° of desired.
(h) MDA + 100 feet/-0 feet.
(i) VREF -5 KTS.
(j) Other- Any parameter pertinent to the phase of flight.
What happens when TOGA pushed on the ground?
TO Lateral mode
TO vertical mode
FMS aligns the aircraft at the end of the runway indicated on legs page
Autopilot disengages
What does TO lateral mode do?
On the ground, generates a wings level command.
After takeoff, it generates a hold command with a 5°bank limit using the heading existing at takeoff
What does TO vertical mode do
Generates an optimized pitch up attitude for takeoff
