A 320 Engine Shut Down
In the Engine Shut Down checklist of A320 there is a line:
If Wing A/Ice off and Eng fire pb sw not pressed:
If performance permits:
X Bleed open
(If no obstacle constraint exists, open the X Bleed. Can someone please explain what is meant by this.
It also says to determine the single engine gross ceiling, decrease by 1200 ft the result provided by the QRH table. Why should we reduce 1200ft when the single engine gross ceiling is already provided?
