The Balked Landing is not fun. Much of the sim training is on the procedure. 2 engine is not THAT big of a deal...I know of at least one time it was used (besides proving runs). SE is not to cool...Basicly you fly at V2 and fly the LOC course. At 0.8 DME SOUTH of the LOC you do a LEFT turn back around to and end up intercepting the normal IPKN miss procedure.
I think the main downside is the winds. Could be a real problem.

As far as full loads to ATL...I have not seen any problems. Every flight is differant though...Anti Ice or not, Hot or Cold etc. There are problems from time to time.
I think the DASH (Q-400) would be the best for many of these flights because of winds and performance problems for the 700. I think the one downside is the range vs. time. For DEN flights no problem, but if you look at the flight times to ORD - ATL - LAX - SFO that is where a jet is needed.

BTW...Any thoughts if the "New" Delta would throw MSP into the mix?
LYNX guys...is it true you have an 18kt. T/O and Landing Tail wind limitation?
