Engines

Question 1

Minimum Oil Quantity

Answer 1

9.5 Qts + Estimated consumption (0.5/h)

Question 2

Engine Fire test

Answer 2

(to check that eng 1 and 2 fire detection and extinguishing systems are operative)

Ensure that: FIRE pb-sw is IN and GUARDED; AGENT 1/2 lights are OFF;

-ENG TEST pb - PRESS and MANTAIN;

Test result:

• CRC;
• MASTER WARN lights;
• ECAM “ENG 1(2) FIRE” alerts;
• ENG FIRE pb-sw lights RED;
• all SQUIB lights of the AGENT pb come on;
• all DISCH lights of the AGENT pb come on;
• all FIRE lights on the ENG MASTER panel come on.

Question 3

During engine start, ground crew reports a fuel leak from the engine drain mast

Answer 3

Run engine at idle for 5 minutes;
If leak disappears, aircraft may be dispatched without maintenance action. If the leak is still present after 5 min, shut down the engine and request the maintenance personnel to investigate the leakage source

Question 4

Why is Eng 2 normally started first?

Answer 4

It powers the yellow hydraulic system, that pressurizes the parking brake.

Question 5

During Engine Start, what happens when selecting ENG MODE selector to IGN/START?

Answer 5

All amber crosses disappear from engine parameters (Upper ECAM)
ENG SD page appears on LOWER ECAM

Question 6

Automatic Eng start sequence (after selecting the ENG MASTER lever to ON?

Answer 6

1: On Lower ECAM- Corresponding start valve in line; Bleed pressure indication green; Oil pressure increases.

On Upper ECAM- N2 Increases

2: AT 16% N2 - Indication of the active igniter (A or B)
3: AT 22% N2 - FF increases

15s (maximum) after fuel is on: EGT increases; N1 increases;

4: At 50% N2- Start valve starts closing (it is fully closed between 50% and 56% N2); Igniter indication off.

Question 7

ENG IDLE PARAMETERS (at ISA sea level):

Answer 7

N1 ~ 19.5%
N2 ~ 58.5%
EGT ~ 390%
FF ~ 275 KG/H

grey background on N2 indication disappears

Question 8

How long must the engines operate at idle or near idle to avoid thermal shock?

Answer 8

2 minutes

Question 9

Procedure to apply, during ground operation, when in ICING CONDITIONS and the OAT is +3ºC or less for more than 30 minutes/ or if significant engine vibrations occur:

Answer 9

Set PARK BRK/ Brake with pedals
Increase thrust to approx. 70% N1 for 30 seconds at intervals not greater than 30 minutes.

Perform this acceleration again just before takeoff.

When operating in icing conditions of FZRA, FZDZ, FZFG or +SN, ice shedding may be enhanced by additional run ups at intervals, do not exceed 10 min, advancing throttles to 70% N1 momentarily (no hold time)

Question 10

When to select IGN during taxi out?

Answer 10

• The runway has standing water; or
• Heavy rain is falling; or
• Heavy rain or severe turbulence is expected after takeoff.
