Overspeed

Question 1

Modern aircraft operate at high altitude and close to their speed limits. As a consequence, temporary over speed conditions can occur in which changing conditions ?

Answer 1

Wind

Question 2

What UPRT concept should be used upon noticing an overspeed?

Answer 2

RCB

Question 3

What UPRT concept should be used to reengage automation after an overspeed?

Answer 3

Happy place

Question 4

What are differences between overspeed prevention and recovery techniques ?

Answer 4

Both keep AP/ATHR on
Recovery does not select speed, goes straight into speed brakes.

Question 5

Should AP be disconnected normally for an overspeed ?

Answer 5

No

Question 6

There is a significant margin between Vmo/Mmo and design limits at cruising altitude and therefore no need to do what upon noticing aircraft reaching Vmo/Mmo?

Answer 6

Rush

Question 7

Will AP usually remain engaged during an overspeed event?

Answer 7

Yes

Question 8

The AP will automatically disconnect if exceedsnxe is large or prolonged or what speed/mach?

Answer 8

VMo+12
MMo +0.03

Question 9

If high speed protection activates and AP disconnects HSP will command what ?

Answer 9

Pitch up input

Question 10

If speed exceeds Vmo +20 or Mmo +0.02, what is required ?

Answer 10

Inspection

Question 11

What is the overspeed prevention technique to be applied if speed is close to Vmo/Mmo?
X4

Answer 11

1. AP on/ ATHR on
2. Select a lower speed
3. Monitor speed trend
4. Use speed brakes as required.

Question 12

What minimises the aircraft from altitude excursions and reduces pilot workload during an overspeed ?

Answer 12

AP

Question 13

What automatically commands thrust idle during overspeed ?

Answer 13

Autothrust

Question 14

Selection of a lower speed not below GD, increases margin below what ?

Answer 14

Vmo/Mmo

Question 15

If at any time the speed trend arrow approaches Vmo /MMO what should flight crew use?

Answer 15

Speed brake

Question 16

What is the most efficient way to decelerate the aircraft without destabilising its trajectory?

Answer 16

Speed brake

Question 17

What is the overspeed recovery technique to be applied if speed exceeds Vmo Mmo?
X3

Answer 17

1. AP on/ATHR on
2. Use speed brakes
3. Monitor idle thrust on EWD

Question 18

For overspeed recovery, AP/ATHR disconnect should be limited to cases where what activates and automatically disconnects AP?

Answer 18

HSP

Question 19

Overspeed recovery, what will limit overspeed exceedance and duration and prevent HSP activation?

Answer 19

Speed brake

Question 20

Overspeed recovery, crew should monitor idle on EWD or do what if ATHR is disconnected ?

Answer 20

Thrust levers to idle

Question 21

What to do if HSP activates ?

Answer 21

1. Smoothly adjust pitch
2. Keep the speed brakes

Question 22

HSP is designed to target what when stick free?

Answer 22

Vmo Mmo

Question 23

HSP is designed to limit excursion beyond Vmo Mmo when what is applied ?

Answer 23

Full forward stick

Question 24

When speed decreases close to Vmo MMO what happens to the HSP?

Answer 24

Deactivates
Remains Manual mode.

Question 25

If HSP activates what should pilot do wth stick smoothly without overreacting?

Answer 25

Adjust

Question 26

Recovery - what should be done initially with happy place - not too early (reoccurrence) or too late (speed decay ).

Answer 26

Retract the speed brakes

Question 27

What should be set as for recovery

Answer 27

Above GD but margin below Vmo Mmo.

Question 28

What button should not be used for noisy overspeed warning and only spurious cautions? Learn to accept good warnings.

Answer 28

EMER CANCEL

Question 29

When can you reengage AP?

Answer 29

Clear of any coloured section

Question 30

Positive spiral static stability in high speed protection is set at what AOB instead of 33?

Answer 30

Odeg

Question 31

High speed protection- what is frozen?

Answer 31

Pitch trim

Question 32

Above Vmo Mmo side stick Jose down authority is progressively what?

Answer 32

Reduced

Question 33

Above Vmo mmo, nose down authority reduced and what pitch order is permanently applied ?

Answer 33

Nose up
