Vilas,
No, it's too soon after release for the sim OEMs to get to grips with it I suspect. We were looking to upgrade the A330 about now but Airbus have deferred this AP/TCAS feature until at least March 2015 and the next release (after 2.5.X I assume). Are there any tangible differences between 1.7.1 and 1.8 for training? |

Since they introduced BUSS, IFLD, back up NAV etc and they went digital. So they went to 1.7 and 1.8 Not much difference between them really |
Does this apply to both engine types?

What are you referring to? |
The 47% N2 vilas thank you.
|
MD
Airbus did not specify the engine. But what it means is that there is a threshold for relight taking place that is monitored by FADEC and not the time. Below that threshold (above 400ft) it attempts an auto start and for that it requires manual ignition. This all gets over in 30 seconds from the time you select ignition and if unsuccessful you move on. |
Doesnt an autostart require crossbleed at such low speeds?
|
This is a quick wind milling relight attempt before N2 drops low. If you see Engine Restart flight envelope, below 18% N2 (CFM) you need starter assist. If this fails you will attempt starter assisted relight later (with no damage).
|
Ok then that makes sense, if the spool has dropped below 18 then much needless to wait.

Communicate?
Coming back to the initial question, when do you think is the right moment to contact ATC with the mayday?
Fly and Navigate first, but if you are going to deviate from the cleared SID, a short "mayday, standby" will be helpful. Maybe this 30 sec ECAM line is a good moment if everything is under control? Thanks. |

Communicate is flexible action. If you are deviating then you can give it before deviating, ECAM stopped call given then resumed again. If continuing till clean up then after retraction to flap1 there is a big gap of inactivity. Generally for Engine fail it is PAN call. |
I used the word generally because I am aware for some companies it is MAY DAY.
|
Vilas: to me the issue with 30 sec is not clear yet, but meanwhile wanted to say thanks for contributions. Keep the brain busy.
|
In my company's FCOM under the ENG 1(2) FAIL abnormal and emergency procedure there is a line that states:
In flight: ENG MODE SEL......................................................... ...........................................IGN Selection of continuous ignition confirms the immediate relight attempt made by the FADEC. It does seem that the 30s starts from the selection of the engine mode selector to IGN then? |
Thanks I should have read your quote clearer that the FCOM will be updated!
|
JS: Good.
See my initial post no 23: The line only appears, when after 30s the ENG FAIL condition is still there. Once you see this ECAM blue line, the 30 had already passed (otherwise it is not displayed). Then: One shall look at the engine if perhaps relight is actually in progress... . if it is > just stand by and wait/hope for the engine to come alive . if it is not > proceed as indicated. |
