Our 321 NEO's have dual cooling. The NEO engines add at most about 2.5-3 minutes to get started in total, at least in my experience.

No idea on the -Max

man, I thought the ER engines (P&W) took awhile to start.

thanks for the info fangs.

the maxxibois don’t have it. Our NEOs do


and if start times are a problem, better boot the 717 out

NEO start (if cooling required) is only marginally longer than a 757 start. ATL can make it work.

Yeah I think it’s less of an issue than people make it out to be. Not to mention ATL movements are down compared to peak RJ days I believe. Easy enough to play the left side right side shuffle all the way home.

Agreed. They could manage with all the disruption due to ramp concrete replacements in the middle of summer. They can manage an extra couple minutes of start time when it happens. Not saying there won’t be disruptions occasionally in various places (BOS, looking at you), or gate holdouts.

Personally I’ve never really had trouble with the Neo start time algorithm because it takes an hour to turn any 321 no matter what.

The start times can be pretty lengthy upwards of 2-4 minutes a motor depending on how long it sat and how warm it is internally. Luckily with the MAX 9’s at least you have plenty of thrust so we’ll usually SET out of the alley so we’re not sitting there blocking all the NG’s in and then spin 1 once we start our taxi out. It’s not horrible until you’re stuck behind one that insists on spinning both.

Pratts on the 757 take right about 2 minutes to start. Pratts on the 767 can take even longer. It’s not going to be a big deal.

It won't. I am referencing "long" in comparison to the CFM's on the NG.
