Question 1

What is the minimum width of pavement required for 180 degree turn?

Answer 1

80 feet

Question 2

What causes the emergency lights to illuminate in the ARM position?

Answer 2

All emergency lights illuminate automatically if airplane electrical power to DC bus No. 1 fails or AC power is turned off.

Question 3

Which flight deck lights are powered by the Standby Power system?

Answer 3

Standby electrical power is provided to the standby compass light, dome lights, instrument flood lights and
selected system information and warning lights.

Question 4

If rapid decompression occurs, which protection has been built in to the flight deck door?

Answer 4

The door incorporates two pressure sensors that unlock the decompression panels in the event pressurization is lost. The decompression panels also have manual release pins.

Question 5

Which flight deck window can be opened from outside the flight deck?

Answer 5

Only the first officer’s window (number two window) can be opened from outside the airplane.

Question 6

When do the emergency exit doors lock?

Answer 6

The overwing emergency exits lock when:
• three of the four Entry/Service doors are closed; and
• either engine is running; and
• the airplane air/ground logic indicates that the airplane is in the air or both thrust levers are advanced.

Question 7

What is the maximum wind for operating entry or cargo doors?

Answer 7

Do not operate the entry or cargo doors with winds at the door of more than 40 knots.

Do not keep doors open when wind gusts are more than 65 knots. Strong winds can cause damage
to the structure of the airplane.

Question 8

Are both cargo compartments pressurized/heated?

Answer 8

The cargo compartments are sealed and pressurized but do not have fresh air circulation and temperature control as do the upper passenger compartments.

However, the recirculation fan system circulates air from the passenger cabin around the lining of the forward cargo compartment. When the overboard exhaust valve is closed, exhaust air from the equipment cooling system is also diffused to the lining of the forward cargo compartment for additional inflight heating.

Question 9

How long does passenger oxygen flow for?

Answer 9

Oxygen flows for
approximately 12 minutes and cannot be shut off.

Question 10

At what cabin altitude do the passenger oxygen masks automatically drop?

Answer 10

The system is activated automatically by a pressure switch at a cabin altitude of 14,000 feet.
