I can see how this make the news after New York, but it is such a common occurrence. The term "emergency" probably doesn't apply either, unless they shut down one engine, which really isn't an emergency anyway. Difficulty controlling the aircraft, or loss of both engines, now that's an emergency.

ASA has no CRJ-100's only -200's...sorry that's just what we have (along with -700's/-900's). OH has -100's, -200's, -700's & -900's.

I know DL.com show's EV having -100's but that is incorrect.

Wow myself having a few thousand hours flying the CRJ series planes I never realized we could dump fuel! Burn off fuel is the correct way but you have to love the media!

Speaking of the -700/-900 series. Burning off fuel is the correct and time consuming way to get back on the ground....There are provisions for an overweight landing in the CRJ maintenance manual. No inspections are required IF certain landing procedures are met (ie max decent rate under xxx feet per min when the tires hit concrete) and the aircraft lands below MTOW but above MLW.

In the event of a return-to-field, maintenance can provide current data so that crews can proceed to land instead of spending time burning fuel.

Another thing that would go through my mind as a pilot and mechanic is ATL is a Mx-base with probably a spare acft or two and resources...

If you suffer an engine failure on a twin, that's automatically an emergency and you must land at the nearest suitable airport.

I know right! I think max ramp weight is 75250lb for the -700 with the 75,000lb certification. Theoretically, IF you didn't burn your 250lb taxi fuel, you could take-off above 75000lb. Realistically, that never happens.

The quote I was thinking of defines a hard-landing/overweight, which then requires the overweight/hard landing check:

"The vertical descent rate is more than xxx fpm and the aircraft gross weight is more than the MLW, but less than or equal to the MTOW."

There are a total of 7 qualifiers. If you can answer 1 of 7 questions as a yes, maintenance is then required to perform the overwieght/hard-landing check. Again, this is on the -700/-900. Maybe someone with -100/200 experience can enlighten us on any differences.

On the 777 we burn about a tonne on the takeoff alone, so even if we were towed out to line up on the runway at Max ramp weight and departed above MTOW, we couldn't land again above MTOW. I am guessing its the same sort of thing for all commercial aircraft.

Look, I see what you're saying... but an engine shut down on a two-engine aircraft *is* an emergency.

Indeed. You'd have to pick up a lot of bugs on the way out.

Under what circumstances could you legally depart above MTOW? After all, if you takeoff above MTOW, then it really isn't MTOW is it?

If the airport had a conveyor belt installed in the runway....  duck 

That is a good question, though.

Unknowningly, but never legal. There's always the oh-crap moment after...

Well different airlines seem to have a different policy on this. Some taxy out and hold near the runway to burn off fuel to get to MTOW while others depart at max ramp weight and assume they are at MTOW when they depart but without ever checking. Those airlines who do not bother to check argue that by the time the aircraft rotates at the end of the runway you will most definately be below MTOW!! For me it is a pretty grey area legally, but I guess they are technically right!
