Oral Review Questions

Question 1

Engine Fire memory items?

Answer 1

-Associated thrust lever = Idle
-Associated start/stop selector = Stop
-Associated Fire Ext. Handle = Pull (No Rotate)

Question 2

Engine cooling between start attempts?

Answer 2

1st to 4th cycles, 1 minute on, 1 minute off. 5th cycle is 1 minute on, 5 minutes off.

Question 3

What are your Engine warm up times and when is an engine considered cold?

Answer 3

4 minute run time for cold engine and 2 minutes for warm engine. An engine is considered cold if it is shut down for more than 90 minutes.

Question 4

APU cooling between start attempts?

Answer 4

-3 Start attempts = 1 minute off
-30 minutes off between 2 series of 3 start attempts

Question 5

Max demonstrated crosswind?

Answer 5

30 knots

Question 6

Max take-off and landing tailwind component?

Answer 6

10 knots

Question 7

Fire Detection systems and bottles?

Answer 7

• 1 Fire loop for each engine, 1 APU. (Core wire surrounded by helium gas in a tube. Loss
  of helium pressure triggers system.)
• Baggage compartment, 2 smoke and 2 heat detectors. 1 high-rate discharge and 1
  metered discharge over 50 minutes. (Stay high if possible, descent causes outflow valves to open increasing seep rate of the agent.)
• LAV Smoke detectors located in the ceiling, automatically discharge at 77*C
• 2 Engine bottles, 1 APU bottle, 2 Bag bottles, 1 bottle above each LAV Waste Bin.

Question 8

What happens when you pull the Fire Handle?

Answer 8

HALFF
–Hydraulics
–Air-Bleeds
–Lip Anti-Ice
–Fuel shut off (Wing)
–Fire Bottle Armed (Must rotate to fire)

Question 9

What is on the Accessory Gear-Box? (Connect with the tower shaft)

Answer 9

HEAPOF
—Hydraulics
—Electrical Generators (2)
—Air-Turbine Starter. (Should shut off by 53% N2 or caution message will display)
—PMA (permanent magnet alternator)
—Oil Pump
—Fuel Pump (Fuel pump and metering unit. FPMU)

Question 10

Max single PACK or BLEED Altitude?

Answer 10

-FL250 (If in icing conditions it’s 15,000 ft)

Question 11

What does the GASPER FAN do?

Answer 11

-Gasper air is used to distribute air to the passenger outlets, the cabin oxygen compartment and relay box, and the rear electronics compartment. (Rear electronics compartment houses important stuff like the FADECS.)
-You can’t disable the GASPER system on the ground. Rear electronics department is very important.

Question 12

What are your minimum speeds in different configurations?

Answer 12

-Minimum maneuvering speed in icing conditions = 200 KNOTS
-Minimum maneuvering speed in clean configuration = 180 KNOTS
-Minimum speed flaps 9 = 160 KNOTS
-Minimum speed flaps 22 = 140 KNOTS

Question 13

Electrical 28 Volt D/C

Answer 13

–4 Engine driven generators (28V / 400 Amps) Come online at 56% N2.
–1 APU Starter Generator (28V / 400 Amps)
–2 NiCads (24V / 44 A) 1 hour
–1 Lead Acid back up battery (24V / 5A) 10 hour
–GPU

Question 14

Electrical: 115 VAC – Single phase static inverter powered by DC BUS 1

Answer 14

–TCAS
–ACARS
–GPWS/WNDSHR

Question 15

Electrical: DC System

Answer 15

-2 isolated networks Left and Right during normal flight operations.
-Only occurs when we have all 4 generators online.
-L ENG: GEN 1 & 3 and power DC Bus 1
-R ENG: GEN 2 & 4 and power DC Bus 2

Question 16

Electrical: Electrical Distribution Logic (EDL)

Answer 16

-Automatically Sheds the shed buses and closes/opens tie contactors in the event of a generator failure.
-Bus ties. Auto- EDL controls system logic

Question 17

Electrical: GPU

Answer 17

-If GPU is plugged in it must be selected to power the electrical system. GPU Available illuminated does not necessarily mean the power being supplied is good. You must check the electrical page to confirm the voltage is sufficient.
-Must deselect the GPU button before GPU is removed.
-Ground service bus is always powered when a GPU is connected.

Question 18

Electrical: During APU Start

Answer 18

-Battery 2 powers the APU start and must be 24V or greater.
-If less than 24V use GPU to start the APU. Then deselect the APU to recharge batteries minimum 30 min.
-Battery 1 is isolated from the load buses and provides stable power to equipment that can be damaged by voltage transients.
-Back up battery is there to provide stable power to the EDL and GCU’s during high loads on the electrical system (APU start).
-APU generator will come online after 95% RPM +7 seconds.

Question 19

Electrical: Electrical System (Rule of 3)

Answer 19

-3 Generators must be online to power the shed buses.
-Moving shed buses to OVRD will power shed buses on the ground only with only 1 generator
-Switch does nothing in the air.
-With less than 3 generators in the air shed buses will auto shed and not be powered.

Question 20

Electrical: Loss of all Generators

Answer 20

-Essential buses are powered for 40 minutes.
-3 APU start attempts are included in that 40 minutes.
-45 minutes if you de-select pitot heat #3.

Question 21

Electrical: Hot Battery Bus

Answer 21

-Courtesy lights (FA Galley)
-Main Door
-Fueling Panel
-ENG Fire Bottles
