switch to ON. - The symbol for the starter valve
On the upper ECAM display unit: opens.
- Monitor the important - At approximately 16 percents N2, the parameters N1, N2, EGT, FF. A or B indication comes into view On the lower ECAM display unit: below IGN.
- Monitor the oil pressure. - At 50 percent N2: The symbol for the starter valve is in the closed position. The A or B indication goes out of view.
NOTE : When the pack valves start to close the FAULT legend of the AIR/COND
____ PACK1/2 pushbutton switches on the AIR COND panel 30VU come on until the pack valves are fully closed.
NOTE : The engine operates at a stabilized ground idle only when there is a
____ positive oil pressure indication. High oil pressure peaks can occur in cold weather because of high oil viscosity. The pressure decreases as the temperature of the oil increases. Ignition automatically starts at 16 percent N2 and the fuel automatically starts at 22 percent N2. The starter and the ignition automatically stop at approximately 50 percent N2. Engine light-off usually occurs at approximately 10 seconds after you beginning of the start attempt (starter shutoff valve open) and within 2-3 seconds after the FADEC selects the fuel on. If the engine light-off does not occur within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the ignition, the fuel flow, and dry motors the engine for 30 seconds. Twenty-five (25) seconds into the dry motoring time, the FADEC systems energizes the two igniters and at 30 seconds, selects the fuel to on. If when you tryed to start the engine for the second time there is no light-off within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the two igniters, the fuel flow and the starter. There is a dry motoring of the engine during after which the FADEC system will select a start abort. This will cause a start abort indication to come on on the upper ECAM display unit. If this occurs, on the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.
- Set the ENG/MASTER 1(2) switch to OFF.

- After the starter is cool, the operator must make a decision: try another auto or manual start or stop and correct the problem.
3. When the engine idle speed is stable, on the ENG panel 115VU:
- Set the
ENG/MODE/CRANK/NORM/IGN/START
selector switch to NORM.
NOTE : It is recommended that the engine operates at or near idle for a
____ minimum of 2 minutes before you increase to high power. You must move the throttle control lever slowly, carefully and smoothly when possible.
NOTE : You can use taxi time at or near idle as part of the 2 minute warm-up
