Weird. Is that normal or safe or right?

It's all three Phil. Not different than leaving your car door open when stepping out for a minute.

it doesnt matter. when they taxiied in they left the reversers open. they do that to save brakes. anyway, engines are started with brakes on usually. anyway, they would most likely notice the reverser handles open when they got into the cockpit and close them before starting the engines.

Seen it quite a bit on Air Force DC-9's.

Especially there at Stuttgart Army Airfield, where that photo was taken (My old base.....WooHOO!!!

Basicly it is to keep the wind from spinning the engines. Seen it a couple of times on Reeve's 727's out on the chain too.

Guess the crews where there too short of a time to bother putting plugs in the engine.

In the C-17 we shutdown like that often. If you are in close proximity to obstructions/equipment/people, starting the engines in idle reverse will deflect jetblast. Reversers also help engine start with significant tailwinds.

L-188, I imagine Reeve's didn't like the effect of a 50 knot wind (and higher) constantly windmilling their engines  Smile

Yeah, that tended to have a lot to do with it.

But when it was blowing that hard we used to park them sideways to the wind with the cargo door on the downwind side.

Would you belive that thing is rated for 60 miles an hour.

The door right? Yeah, eventually it'll become a sail I guess. I think I remember you telling about the King Air (Forest Service?) at Cold Bay that was basically flying an inch or two off the ground in its tiedown chains. Maybe I'm getting my stories mixed up.

Yeah that was me.

It was the state troopers one.

It is pretty impressive when you are sitting in a 727 and the lift the rear airstair in those winds. You can actually feel the airplane bouncing on the oleo struts.

Actually it suck unloading an aircraft when it blows that hard. It may be 50 on the outside but the space between the bround and the belly acts like a big venturi tube.

May actually be blowing closer to 70 or 80 went you are emptying the belly compartments.

Lot of times time our fleet manager remember us to avoid the use of the reverses during the taxi but it is very usefully to do not over load the brakes.

Someone told me that having the reversers deployed while parked (engines off) reduces the engines turning in the wind and prolongs engine life.

We park over night with the thrust reversers open to prevent the wind from blowing the inlet plug out. Not fun to go searching the airfield the next morning. Plus it prevents a straight open shot for something to get blown or tossed into the exhaust. Part of the morning check is to close the thrust reversers prior to engine start. The only time I have seen the DC-9 use reversers during taxi, was on an icy taxiway, and then only to idle.
