Can hurricanes and typhoons form over land?

Answer 16

No.

Question 17

When is typhoon season in Hong Kong?

Typhoons may affect Hong Kong any time between May and October, most likely between mid-July and late September.

Question 18

What is V1?

Answer 18

Decision Speed.

Question 19

What is VMCG?

Answer 19

The minimum control speed on the ground.

Question 20

• Runway condition (Wet/Dry)
• Engine power settings
• Crosswinds.

Question 21

Relation between V1 and VMCG?

Answer 21

V1 can’t be lower than VMCG.

Question 22

What the vortex generators do?

Answer 22

They energize the boundary layer, delaying flow separation and aerodynamic stalling.

Question 23

Advantages of aft Center of Gravity?

Answer 23

• Fuel sufficient
• Less drag.

Question 24

Explain VMCA.

Answer 24

Is the minimum control speed in the air for a multi-engine aircraft.

Question 25

Why use carbon brakes?

Answer 25

Higher braking efficiency and safety in a wide servicing range.

Question 26

Define service ceiling.

Answer 26

Maximum altitude where, at least, 100ft/min of climb can be maintained.

Question 27

How far to start descent when at FL 330 and 1500 fpm?

Answer 27

Around 99 NM.

Question 28

Can EGPWS work without GPS?

Answer 28

Yes.

Question 29

What prevents Dutch Roll?

Answer 29

Yaw dampers prevent Dutch roll on swept wing aircraft.

Question 30

How do we correct for Dutch Roll?

Answer 30

With rudder.

Question 31

How do you control an aquaplane?

Answer 31

By using the antiskid braking systems.

Question 32

What is the most effective means of stopping on a wet runway?

Answer 32

Thrust reversers.

Question 33

If you're at 33,000 ft with a temp of -55 deg, what's the ISA deviation?

Answer 33

-4 Celsius.

Question 34

Why is aft CG desirable for long range cruise?

Answer 34

Lower trim drag -> lower fuel burn -> longer range (more fuel efficiency)

Question 35

How is range increased when flying into a headwind?

Answer 35

By selecting LRC or for max range use MRC.

Question 36

What do tire temperatures prior to takeoff depend upon?

Answer 36

* A/C weight * Taxi speed * Tire pressure * OAT * Airport elevation.

Question 37

How do flaps affect the take-off ground run?

Answer 37

It reduces T/O ground roll.

Question 38

What is a microburst?

Answer 38

A severe downdraft vertical wind from a cumulonimbus cloud.

Question 39

What is the biggest hazard in heavy rain on final approach?

Answer 39

* Reduced visibility * Wind shear * Reduced landing performance.

Question 40

When do you turn on engine anti-ice?

Answer 40

In visible moisture, on at temps between +10°C TAT and -40°C SAT.

Question 41

If you fly into a cloud and the TAT is -47ºC do you need anti-ice?
