Engines

Question 1

If the engine generator fails, where will the FADEC find alternate power?

Answer 1

DC Essential bus

Question 2

When might I need a windmill start?

Answer 2

If wing anti-ice is on.

Question 3

To move an engine to ALT mode, the throttle needs to be in what position?

Answer 3

Mid-range.

Question 4

TR stow airspeed limits?

Answer 4

200 KCAS

Question 5

Engine Fire Loop Alert red warning annunciator. What does this mean and what can we do about it.

Answer 5

It means either fault or fire. QRH. EC Section. Good test, good news.

Question 6

What fire extinguishing bottle goes to the APU?

Answer 6

2

Question 7

Will the APU shutdown for fire on the ground or in the air?

Answer 7

The APU will shutdown for fire on both the ground and in the air but it cannot fight its own fire.

Question 8

What temperature would illuminate an AFT FLOOR HOT warning?

Answer 8

250 degrees.

Question 9

What temperature would illuminate a L or R EER HOT, BAGGAGE EER HOT, OR FORWARD FLOOR AREA HOT caution capsule?

Answer 9

150 degrees.

Question 10

The only smoke detector on the G550 is located where?

Answer 10

Baggage compartment.

Question 11

How many gallons of fuel does each hopper hold?

Answer 11

190 gallons.

Question 12

The hydraulic pump case drains are cooled using what?

Answer 12

Fuel, through a liquid to liquid heat exchanger in the fuel hopper. Could potentially be the source of a hydraulic leak that you cannot find (it could be in the fuel hopper).

Question 13

If you do not have an asterisk on the fuel control panel (behind the pilot’s seat), to what level will the aircraft fill?

Answer 13

41,300 lbs.

Question 14

What does the little red light next to the single point refuel port tell our ground servicing personnel?

Answer 14

Fuel is being pushed into the plenum — about 2% of the whole wing is in the plenum. Approximately 61 gallons.

Question 15

At what temperature will you get a fuel temperature CAS message?

Answer 15

37 degrees.

Question 16

What are appropriate indications from the fuel system test?

Answer 16

7000, 7000, 14000, and L-R FUEL LEVEL LOW CAS message.

Question 17

When do the fuel level low lights illuminate?

Answer 17

When there are 650 pounds left in the hopper.

Question 18

What altitude will the engines be able to suction feed?

Answer 18

20,000’

Question 19

What are the power sources for the fuel pumps?

Answer 19

The main fuel pumps are powered by the ESS DC buses while the Alt fuel pumps are powered by the Main DC buses. While the power going to the pumps is DC, it is converted to AC inside the housing and the pumps themselves are AC.

Question 20

What position should the fuel shutoff valve be in when checked during the pilot’s walk around?

Answer 20

7 o’clock

Question 21

What is the maximum fuel imbalance during single point refueling?

Answer 21

500 lbs

Question 22

What is a required item as part of the NACA vent on the underside of the wing.

Answer 22

The vortex generator, as per the CDL. Puts a light pressurization on top of our fuel.

Question 23

If over-serviced, where will fuel drain from?

Answer 23

The overboard vent from within the plenum.

Question 24

When does the fuel imbalance indicator appear?

Answer 24

At 100 lbs.
Maximum deflection at 500 lbs.
Turns amber at 1000 lbs (you will also receive a fuel imbalance CAS message).

Question 25

How do you fix a fuel imbalance with the cross-flow method?

Answer 25

Open the crossflow valve and “light up the light (side),” that means turn off the fuel pumps on the light side.

Question 26

When do we use the inter—tank fuel balancing method?

Answer 26

When fuel temperature is 0 degrees or less. Page EE24 of the QRH — trim in the direction of the “heavy tank” first, and then open the inter-tank valve to balance fuel between the two wings.l

Question 27

What is the minimum oil temperature for an engine start?

Answer 27

-30 degrees C.

Question 28

What is the FCOC?

Answer 28

Fuel Cooled Oil Cooler.

Question 29

How many fuel probes are in each wing?

Answer 29

19.

Question 30

What is the residual temperature (TGT) limit for fuel to be introduced on a subsequent start?

Answer 30

150 degrees C.
