APU bleed after start and other quick questions

Featured Replies

Hi there,

so far I'm more than happy with the product, I got use to all procedures and use it with button control only. But a few small things made me wonder

1. The PM turns on apu (during taxi) and apu bleed after shutdown. He doesn't turn it off after engine start though. Seems it's not part of his after start flow. Is that correct? 

2. When exactly does the PM start the timer and what purpose has this? 

3. Can I somehow tell him to please leave the table in? 

4. Do always both pilots make a flight controls check? As a passenger I recall always seeing the ailerons "checking" only once ....

5. Do I have more control options or commands with voice control? 

Greetings

Stu

Glad you like it!

 

1. Correct, turning off the APU is part of the PF's flow.

Look in the "A320 Flow Pattern" section here. It shows it all quite nicely who does what.

2. Which timer? Chrono goes on when TO thrust is set... ET at first aircraft movement (that last one is airline specific).

3. No... it's hard coded.  

4. That's the way Airbus wants it.  Some airlines may do it differently, but we basically modeled it the Airbus way.

5. You do.  Voice by its nature is more flexible and offers more options for control.

 

Hi Stu,

I can help with a few of those.  EDIT:  Byork beat me to it while I was typing it all out.  Take his more knowledgeable answers of the software over mine!

1. The APU bleed (followed by APU shutdown in most cases) is part of the PF flow after engine start.  For shutdown, the PM turns on the APU bleed just before you shutdown the engines.

2. The PM appears to start the timer from the start of taxi after engine start, and stops it after arriving on stand, this is to record the block time for that sector.  Some airlines in reality start this from the commencement of pushback and/or engine start.
For a bit of extra information it is worth mentioning that you are also expected to start the chrono at various stages to ensure sufficient engine warm-up/down time has elapsed before setting takeoff thrust or shutting down after landing, in addition to the start of the takeoff roll to monitor thrust time limits should anything abnormal happen that may take you close to exceeding those limits (such as an engine failure after V1 and the resulting sluggish climb that would produce, requiring TOGA thrust for a lot longer than normal).

3.  I do not know of an option that would change this.  Maybe someone else does.

4.  Normally both pilots do a flight control check, although individual airlines can have their own Standard Operating Procedures which can modify this.

5.  I'm sure I've read somewhere that the voice control method has more functionality, but off the top of my head I cannot tell you exactly what those are. Until someone else replies it would be worth checking the manual as I'm confident the information is in there somewhere.

Regards,
