Q

What prevents the landing gear lever from being raised inadvertently on the ground?
Is there any way to manually override this system in the air?

A
  1. On the ground, the lever is prevented from moving to the UP position by an automatic lever lock that is controlled by the main gear tilt sensors.
  2. When the gear is not tilted, the lock is engaged. The lever lock can be manually overridden by pushing and holding the landing gear LOCK OVRD switch.

Q

T/F: Good technique when raising the landing gear is to press the brakes in- order to prevent the wheels from spinning as they enter the wheel well

A

FALSE
Automatic wheel braking occurs during gear retraction.

Q

How is normal gear extension accomplished?

A

When the landing gear lever is moved down, the landing gear doors open, the gear is unlocked, and the GEAR and DOORS light illuminate. The gear is hydraulically powered to the locked position. Afterwards, all hydraulically actuated gear doors close and the main gear trucks hydraulically tilt to the flight position

Q

How is alternate gear extension accomplished?

A

The alternate landing gear extension uses an electric motor to TRIP the locking mechanism for each gear. Selecting DN on the ALTN GEAR EXTEND switch releases all door and gear uplocks. The landing gear free-fall to the down and locked position.

Q

What are the four types of braking systems available? Which braking systems provide Antiskid protection?

A
  1. NORMAL BRAKES: Each main gear wheel has anti skid protection
  2. ALTERNATE BRAKES: Only laterally paired wheels have anti skid protection
  3. RESERVE BRAKES: Only laterally paired wheels have anti skid protection
  4. BRAKE ACCUMULATOR: Each main gear has wheel has anti skid protection

Q

According to the FCOM, how many brake applications can the Brake Accumulator provide in the event of a normal + alternate brake system failure?

A

The brake accumulator can provide several brake applications or parking brake application.

16
Q

What conditions need to be met for the RTO to work ? When would it not work ?

A
  1. Above 85 knots groundspeed, the airplane is on the ground, and both thrust levers are retarded to idle.
  2. If RTO initiated below 85 knots the auto brake function will NOT work.
17
Q

How many deceleration levels are available with the auto brake system upon landing?

A

5 (1, 2, 3, 4 and MAX AUTO)

18
Q

When does AUTOBRAKE application occur upon landing?

A

Autobrake application occurs slightly after main gear TOUCHDOWN (both thrust levers must be retarded to IDLE and the wheels have spun up).
Deceleration is limited until main landing gear truck untilt occurs, then deceleration increases to the selected level.

19
Q

Under what circumstances will the Autobrakes automatically DISARM after landing?

A
  1. Manual braking
  2. Advance thrust levers
  3. Speed brake down
  4. Selecting disarm
  5. System fault
20
Q

When is the tailskid automatically raised and lowered in flight?

A

The tail skid uses the main landing gear actuation system. It is raised and lowered whenever the landing gear is retracted or extended

21
Q

While taxiing out for departure you observe an AIR/GND SYS advisory message on the EICAS. Can you take off with this condition?

A

An EICAS advisory message AIR/GND SYS or NOSE A/G SYS indicates that some portion of the sensing system has failed. Affected equipment and systems will NOT operate normally and therefore takeoff is not allowed.

22
Q

When are the master CAUTION lights and aural annunciations inhibited?

A

The inhibition begins at 80 kts. and continues until 400 feet AGL or 20 seconds elapsed time following nose gear strut extension, whichever comes first.

23
Q

When are the MASTER WARNING lights and FIRE bell inhibited?

A

The inhibit begins at nose gear extension during rotation and continues until 400 feet AGL or 20 seconds elapsed time, whichever comes first.

24
Q

What is the priority and color of the Alert / Warning messages displayed on the EICAS?

A
  1. (Red)
  2. (Amber)
  3. (Amber, Indented)
25
Q

What actions happen on the flight instrument displays during a TCAS RA event?

A
  1. TCAS Voice Alert sounds
  2. TCAS vertical guidance is displayed on the ADI + VSI
  3. The TCAS red message TRAFFIC is displayed on the ND
26
Q

A resolution advisory (RA) is a prediction that another airplane will enter the TCAS conflict airspace within approximately __________ seconds?

A

20 – 30 seconds

27
Q

A traffic advisory (TA) is a prediction that another airplane will enter the conflict airspace within approximately ____________ seconds?

A

35 – 45 seconds

28
Q

What scenario would cause the ALT ALERT light to illuminate on the center forward panel?

A
  1. -300 aircraft: Between 300 and 900 foot deviation from selected altitude
  2. -200 aircraft: between 250 and 750 foot deviation from selected altitude
29
Q

How can a Warning message be cleared from the EICAS? How can a Caution and advisory message be cleared from the EICAS?

A
  1. Warning alerts can only be cleared by correcting the condition that caused the warning in the first place.
  2. All caution and advisory message can be cleared. When the last page is displayed, pushing the CANCEL/RECALL switch clears all displayed caution / advisory alerts.
30
Q

Describe a scenario that would cause a takeoff configuration warning. How can it be canceled?

A
  1. Flaps are NOT in the takeoff position
  2. PARKING Brake is ON
  3. Spoilers are NOT down
  4. Stabilizer Trim is not in the Green Band

*Takeoff configuration warnings are armed when the airplane is on the ground and thrust is in the takeoff range on either engine.
Fixing the issue will cancel the warning.
The warning will also cancel on rotation

31
Q

Describe a scenario that would trigger a landing configuration warning.

A

If any landing gear is not down and locked and either the flaps are in a landing position (25/30), OR any thrust lever is at idle with radio altitude below 800 feet.

32
Q

What is the maximum normal gear operating/extended speed?
VLO
VLE

A

270 KIAS / 0.82M

33
Q

On what hydraulic system is the brake accumulator on ?

A

Right system
