Strange. I'm assuming it was un-commanded. It's...concerning that something like that could happen. Presumably the only thing keeping the reverser stowed in flight was the squat switch?

pilot was showing off for camera man OP. manual engine thrust steerage.
United 232 without the altitude but yeah, holy shit. |
|
not un commanded if he took off again
it is not uncommon for it to show not stowed after landing so we open it and close it and repeat until we get a stowed indication. |
|
3800 hours in the DC9 as a Captain, but not the MD series of airplanes. Does not matter, they have the same reverse system. Looks to me like he had an erroneous indication of not stowed. Regardless, it could have been mechanically locked out and MEL'ed prior to departure, you don't need the reverseres for flight anyway.

No. That isn't how it is, at all. |

My money is in poor or "atypical" Captain technique.
Look how long he kept the buckets out on roll out. Then left turns with the T/R deploy. My money says the captain was "saving his brakes" and the f/o was rolling his eyes. |

Guess what happens when the engine doesn't light off? you try again. Know how many gate calls I've gotten for that? |

There was a 717 that had a thrust reverser deploy on takeoff from STL many years ago.....2001-2002 maybe? It was about the same time when one had the engine fire on takeoff. Will try to remember or find the details.

I love old airplanes. After pilot training, my first panel was a C-130E that hadn't changed much since the 60s. When I first started flying it, I was humbled, but am a better pilot for it. The simplicity of the old stuff was wonderful, especially since I could level my ADI during any phase of flight. 0VVI on approach? Level it. 0VVI, dirty, door open on the run in? Level it. None of this "well, 2.7748 degrees is level right now... so fly that." NDB approaches were also easy on the old panel. However, I've never flown a true "glass" airplane and am no expert. The closest was a Beech 400, and that was 1st gen glass. I would love to fly an MD-80 before they are gone. |

Like MACH said, it's not uncommon on the -82/83 for a reverser unlocked light to stay on after you stow the buckets. Usually cycling the affected reverser a couple of times fixes the problem.

Just as I suspected, it's some kind of weird, fucked up Lear thing. Pretty silly on a centerline thrust jet. It's funny how you exptrapolated that, to assume that's how all aircraft would be. Wouldn't be safe, otherwise. Pretty much every normal aircraft deploys independantly, and it isn't unusual to pick up a plane with the TR lever safety wired on one side. It's understood, that the pilots will show a bit of finesse in deploying the one good one. And this will really blow your mind: Large Turboprops will also go into reverse independently. It is helpful on an icy runway, but can get wiggly, if it happens inadvertently. |

It's been a long time since I flew a CE-500 but I don't remember them being able to deploy one TR but leave the other stowed. That just seems like a dumbass idea to me begging to drag a newbie off the runway. I don't have a CE-500 manual anymore so I can't back that up with anything.
Its been even longer since I flew a BE-200 and I don't remember them being able to enter reverse independently either. That just doesn't seem like a good idea at all. |

All of a sudden, I'm hoping my 2 scheduled flights on 88s this year get switched.

The FC200 35/36.

Yeah...I'm actually a pretty good stick and would not have faired well flying in Alaska without finesse. I've used lots of asymmetric thrust for many phases of flight but deploying one TR doesn't seem like a good idea. It's not any different than having anti-skid on only of the mains. |

This discussion reminds me of the following TAM airlines crash. iirc, they had an inop reverser on the right engine and the procedure was supposed to be to leave thr right throttle in the idle detent while bringing the left into reverse. The pilot left one up and pushed the jet off the end.
There were some FM changes just prior to this that played into it as well. I dont recall those though. https://en.m.wikipedia.org/wiki/TAM_Airlines_Flight_3054 |

Challenger 600/601 will deploy independently. You can go full power with one TR on the Falcon 50.
|

Some aircraft allow reverser deployment while airborne. The C-17 and DC-8 come to mind.

I flew a 501SP for 3 years and it would deploy independently. I also flew a King Air 200 for 8 years and it would enter beta/reverse independently.
