Not plausible in the least bit. You would need to take off from a runway the likes of Qamdo_Bangda_Airport at 33,000lbs in -40C temps.

Don't know the RJ but as you accelerate above the speed which nosewheel steering disengages and Vmcg you'd have to reduce the good engine a bit so that you can maintain directional control. Once you accelerate to Vmcg back to T/O power and rudder will keep it straight.

Boredom kills.

IIRC, about a month ago, the Director of Flight Ops at Trans States took a take-off clearance with one engine shutdown. When they couldn't get it going on the runway, he cancelled T/O clearance and taxied back to the gate. Unfortunately for him, there were four TSA non-revs in the back and I can only imagine the looks of concern and confusion they were passing each other.
Of course, I can neither confirm nor deny whether any of this really happened. A rumor that followed was that he was removed from his position and his certificates were pulled. Some of the active Trans States guys can chime in any time and correct me if I'm wrong. |

Whether it will or won't in reality is a question that I hope NO ONE will ever attempt to answer. However, if it helps, I HAVE ACTUALLY DONE IT IN THE SIM. I did it successfully off Rwy 27R in Atlanta. The challenge is to nurse the power in until your speed is high enough for single engine directional control. It took nearly the entire runway. Once I rotated, it flew just fine.

While i was in sim, we tried this, the airplane will almost fly itself off it you let it roll down far enough. So yes i would say it's possible.
On takeoff, you just had to add thrust slower so you had enough rudder authority but even with a med fuel load, it wasn't a super challenge. Now, on the line? No way one could 'accidentally' takeoff single engine. |

As Rick alluded to above some 3 and 4 engine aircraft have provisions for this sort of thing. I can only speak to the C-130. There were provisions for three engine take-off's in the -1. Min runway length, OAT, gross weight...etc... all within some pretty tight tolerances. In addition the MAC put even further restrictions on it to the experience of the crew I believe. I suspect that it required MAJCOM approval to perform anyway. We also had a provision for doing a "windmill taxi start" in the case of a blown starter on one of the engines. You had to have 7 or 8,000 feet of runway and you accelerated down the runway using the windmilling prop to start the engine. You then taxied back and took off. Again.. lots of restrictions etc... but it was an authorized procedure.
also makes the chance of a singe engine approach more real. only big airplane i know of that on a single engine approach you were committed when you dropped the gear. there was no go-around. |
Hawker400XP will do it. Take my word for it.

Didn't XJ and ZW ferry engines around with the 146/Avro?
