Default C17 question.

I’ve noticed lately in the coverage of Afghanistan failure, that the thrust reversers are deployed while aircraft are parked. Personnel are loading. Can’t tell for sure if engines are running. Why?

Probably keep the engines running while minimize idle thrust in the loading area.

That would be a “hot” on-load. Pretty typical for that kind of hostile environment. Get ‘em on and GTHOT!

They didn't seem to be in a hurry in the pics. I understand keeping the engines running so you can get out quickly, but FOD and other injury might seem to be a concern. Besides, the thrust blockers only block the fan not the core. But, whatever ya'll say.

Considering they’re at Kabul with no Maint and no huffers, they probably left them running to avoid the slight possibility that they wouldn’t start again.

Yes procedures for engine running off/onload is to have the engines in reverse idle. This directs the exhaust upward so as to not hurt anyone.

Yep, and a core TR disagree was a reason to pull the fire handle. No way to know if hydraulics were leaking into the core, I had it happen twice. Once at Al Asad and the other at home station.

EROs are the best way to keep ground time to a minimum. I would imagine they had crews doing double or triple shuttles in a single duty day to get as many people out as possible. Part of me is really glad to no longer be active duty, but part of me wishes I had been there to help.

Technically, the plane is more reliable if you don't shut down.

Burn is only about 1000 #/hr/motor.

A T/R issue is the risk, but worth the gains. 4 childbirths on these fllights I heard.

Moose -

I'm going to guess the latter half of your statement.
This is probably a HIGHLIGHT of anyone's career in strat lift I'd imagine.
Humanitarian lift - especially under such conditions as these - has to be high on the list of major career satisfaction and something that I bet those crews will be telling their grandkids about.

LIVES SAVED PERIOD.
