Crossbleed is shut as part of shutdown checklist. In response of the fire push button been pushed (damage), it must be closed in order to isolate both side of the bleed system and to avoid bleed/ ac contamination (smoke, fumes, odors). Due to the bleed system architecture design (APU Bleed feeding line positioned to the left side of the crossbleed valve) in case of ENG 2 failure with damage (ENG2 fire PB pushed) the APU bleed can still be used to supply bleed pressure as long as the crossbleed is set close position PRIOR of selecting APU bleed p/b to position on. This is a very important step to be observed since as per crossbleed logic, when the crossbleed rotary selector is set auto, by setting APU bleed to on will automatically open the crossbleed valve and consequently contaminating the AC system. Another important point is to remember that APU bleed has priority over engine bleed. Using APU bleed to supply bleed pressure is also very handy in case of immediate return to departure airport under overweight conditions as it allows pack to be supplied from APU bleed and the ENG or ENGINES to achieve best performance (no bleed being tapped from it). Regarding REV usage when one is inoperative it can still be used, in this case both thrust levers must applied.

Hello captain, how would the PTU work after switching off the engine master switch of 1 engine ? In FCOM its mentioned PTU will work when the differential pressure is more than 500 psi between Y&G , and both engine master switch should be off or both should be on
engine damage is suspected with the following symptoms: -high EGT above the red line -mismatch or absence of rotor speeds -hydraulic system loss -vibrations -repeated/uncontrollable engine stalling
engine is considered damaged when vibration occured; N1 is 0; EGT is low. X bleed to shut to isolate and prevent smoke from fired engine to the other and to cabin. I still do reverser on landing 1 eng. Anything do I miss? please advise. thanh you, cap.
Hi good job Nam, engine also considered damaged when there is loud explosion and no readings on engine parameters. Crossbleed to shut to prevent contaminated bleed air to enter. And yes reversers can be deployed when landing with one engine. Good answer Nam!

Excellent, very detailed answer. Great job!
whats the reference´s manual?

Again, excellent video, it helps a lot the pilots who are training in the simulator. Thanks for sharing 👨✈ the video. 👨✈
Most welcome, glad you enjoyed it.
In case of engine damage, we close the crossbleed to preserve the other engine sistems
Engine Damage when 2 out of 5 options apply: 1. repetitive engine stall, 2.airframe vibration, 3.high EGT, 4.stuck shafts, 5.hydraulic generation of failed engine lost.
good answer.

Very nice
TOGA for both engines? Or only the operative engine?
Some people say only to the operative, I cant find any reference on the manuals.
excellent guide for repetition of knowledge, ths
You are welcome.

PTU should still work as long as there are still hydraulic fluids and pressure left.
Alright, thank you so much I have my airline interview in few days for the post of junior first officer :))

Wishing you the very best! Let me know the good news
engine damage is suspected with the following symptoms:
-high EGT above the red line
-mismatch or absence of rotor speeds
-hydraulic system loss
-vibrations
-repeated/uncontrollable engine stalling
If my engine is secured but I m still below engine out acceleration altitude,can I level off to clean the aircraft or wait ?
You must to wait until reach de acc alt

Engine is considered damaged when its missing :)
Best answer i have heard so far, hahaha!
