KV ERJ Taxi (14)

Question 1

With the left engine and APU running, what powers the electrical system?

Answer 1

Following electrical power priority Onside, Inside, Outside, Cross-side; both IDG 1 and APU are supplying power to the electrical system.

Question 2

What conditions would preclude a single engine taxi?

Answer 2

1) Ramp/taxiway contamination,
2) maneuvering room in the ramp/gate area is marginal,
3) taxi time to runway is expected to be < 5 minutes,
4) Airport specific regulations prohibit single-engine taxi,
5) or there is risk of injury to personnel or damage to equipment.

(SOPM 4-5.3)

Also, consider airplane weight, uphill slopes, time to warm-up engines, and time to the active runway.

Question 3

During a single engine taxi with the left engine running, which hydraulic pumps are running?

Answer 3

1) EDP 1,
2) ACMP 1/2,
3) ACMP 3A.

Assuming - HYD SYS 1, 2, 3B,- AUTO, and 3A turned ON.

Question 4

With the right engine running on a single engine taxi, which hydraulic pumps are on?

Answer 4

ACMP 1, EDP 2, ACMP 3A. Assuming Electric pump 1 is turned ON and 3A turned ON.

Question 5

What is the maximum taxi speed on a dry surface while taxiing straight ahead?

Answer 5

30 kts. (SOPM 4-5.3)

Question 6

What is the maximum taxi speed in a turn on a contaminated surface?

Answer 6

5 kts. (SOPM 4-5.3)

Question 7

If Hydraulic Pump 3A fails on the taxi out, what is the system logic for Pump 3B?

Answer 7

Hydraulic pump 3B will only turn on when 3A fails.

Question 8

Assuming a single engine taxi with the APU off, will you have windshield heat?

Answer 8

TWO AC Sources
Both Left and Right windshield heat systems will only operate simultaneously if there are at least two AC electrical sources. (AOM V2 14-12-10.10)

ONE AC SOURCE -
Ground Operation- With Single AC Power (e.g.) ONE IDG - each windshield heating controller performs it’s normal BIT heating the corresponding windshield for 120 seconds.

Abnormal Operation
Single AC electric source in-flight - only the left windshield heating is powered. If the left windshield heating fails, the right windshield heating becomes available.

Question 9

What part of the Airplane is normally used as the representative surface?

Answer 9

Normally, the left wing leading edge and upper surface is used as the representative surface for all SkyWest aircraft. (GDPM 02.11)

Question 10

What is the difference between a Pretakeoff check and a Pretakeoff contamination check?

Answer 10

A pretakeoff check is a check of the aircraft’s representative surface for frozen contaminants. This check is conducted within the HOT, just prior to takeoff.

A pretakeoff contamination check is conducted after the HOT has been exceeded to ensure wings, control surfaces, and other critical surfaces are free of all frozen contaminants. This check must be completed within five minutes prior to takeoff. (GDPM SP2800 02.11)

Question 11

Can we depart if our holdover time has expired?

Answer 11

Yes. If a pretakeoff contamination check has been conducted within five minutes of takeoff and it is found that the wings, control surfaces and other critical surfaces are free of all frozen contaminants.

Question 12

What does the deice checklist tell ERJ crews to do with the elevator trim prior to deice?

Answer 12

ELEVATOR TRIM – FULL NOSE DOWN. (GDPM SP2800 D.6/D.7)

Question 13

What normal checklist is delayed if deicing is planned?

Answer 13

AFTER START CHECKLIST

Question 14

When are the flaps extended on the ERJ after Deicing?

Answer 14

During the BEFORE TAKEOFF CHECKLIST. (GDPM SP2800 D.6/D.7)
