Yes, same for IAE
With regard to engine cool down and thermal stabilization, if you want to get technical, you can start the timing from the time you go to idle thrust. So, let's say you pull the thrust levers to idle at 50 feet AGL on the approach and use no reverse thrust or idle reverse thrust on the landing roll out. You can start the three-minute timing from the time you come to idle at that threshold crossing point. Once you pull the thrust to idle and leave it there, it's really part of the three minute cool down. But, that's really not what is intended. What is really intended is for you to srart the clock after clearing the runway and doing your after-landing flow and checklist. As long as you have the thrust at idle (during your taxi in) and pretty much leave it there, you can keep the clock running, and, after three minutes, you can shut it down.While the CFMs and IAEs are the same in this regard, CFM adds one other phrase that IAE does not...and, that is: on the CFM engine, you can shut down the engine after only one minute of cool down "if operations require". In my opinion, under normal operations, I can see no reason to 'operationally require' a shut down after only one minute. Three minutes minimum is what you're looking for...four minutes waiting is better, etc. What is optimal is up to you, the captain. In this forum, we've beaten to death the issue of single-engine taxi, so I won't go into that here.There are, in some A-320 series aircraft, a 110 VAC, 400 Hz outlet. Some guys use that for charging their cell phones or laptops. However, please look in the fine print of the aircraft limitations. It is prohibited to use this outlet during takeoff and landing.There have been many threads in this forum about the suitability of this outlet to charge (and/or use) electronic devices from these outlets. So, again, I won't go into that, here. I've never seen anyone have any problems with their computers, etc., after using these outlets for this purpose.Fly Safe,PantLoad
