CFM Leap-1A cooling time?
Not a NEO driver, but I've heard various times that there is an extended start up time due to a dual engine cooling cycling being required upon engine start. Something to do with an evening out of temperatures throughout the powerplant to prevent thermal shock/expansion in the matierals, is that correct? Is it something like 50secs per side? Would someone have any documentation to explain?
Also is there a significant difference in start up time of the Neo outfitted with the Leap-1A or P&W1100G compared to previous iterations of the 320? Because of the cooling cycle? Is this extending turnaround times or negligible?
Thanks
