US 757 With Overwing Exits Why?

I don´t know if this topic have been covered before, but I just want to know why all US carriers have their 757 with overwing exits and other airlines don´t?
Is that a FAA regulation for US carriers to have the two overwing exits or is it that airlines can choose to have the exits over the wing or just the 4 doors on each side of the aircraft?

Not ALL US Carriers have Overwing Exits. NW has some with overwing, and some with the plug style. It is basically an airline's choice, and some have to do with the seating arrangement, while with others it is simply choice.

I believe overwing exits are a sign of ETOPS 757's. I flew an ancient but well-maintained America West model several years ago. After the trip, I discovered it was an ex-Eastern Airlines -225 model (N914AW, #38 off the line).

I sat in the emergency exit row (#9) - there were only two seats in this row. I asked the flight attendants about that, and they pointed out it is an overwing exit. I asked, "for ETOPS routes?". The flight attendant's eyes got big as she said, "uh, yeah!!". Not used to passengers knowing ANYTHING about the plane...

It's just a different configuration of the aircraft. That's just like AA and UA 763's only have 4 doors and 4 window exits while BA 763's have 8 doors and AF's old 763's had 8 doors as well

Nah. It's just a customer option, it's not indicative of anything. For example, native AA 757s with overwing exits ARE NOT ETOPS certified, while the ex-TW four door birds were ETOPS certified at one time.

It is a customer option, but I believe that the option of window exits came later on in the production cycle. I can't remember exactly why, but I think they were preferred by one customer, and Boeing began to offer them. The first 757s all have the 8 exits I believe. (but I may be wrong here)

TZ's 752 do not have overwing exits, at least unless they have acquired more since I was furloughed and I know that has not happened.

There 753's do have overwing exits to satisfy the 90 second evacuation rule.

UA just blew and wing slide in-flight. That is pretty indicative of overwing exits unless it provides a slide for a door. That would be kind of unusual.

The FAA mandates that no seat can be more than 50 linear feet from an exit. The 90 second rule probably doesn't have much to do with the decision to outfit TZ's 757-300's with double Type III overwing hatches as the 90 second rule is a certification requriement only for the aircraft type and during this testing the FAA could have chosen to block off all of the overwing hatches as unusable. Remeber the FAA certification test involves using only half of the available exits. Door config is part of the option package. Some operators utulizes the second L2 door as the entry door instead of L1 in some instances which in both configs is the same size as the L1 door.

This is partially correct. Not all overwing 757's are ETOPS, however they are the only type of 757-200 that can be certified for ETOPS.

NWA has two varieties of 757, the 5500 series with the type-2 exits, and the 5600 series with overwing exits. Only their 5600 757's can be certified to ETOPS because they have two independent fuel transfer valves, the 5500 series only has one. Part of ETOPS certification is that the aircraft either has:

A) A single permenantly open fuel transfer line between wings, or
B) Two independent fuel valve transfer lines between wings

Since their 5500 series only has the single x-fer valve, they can't be certified for ETOPS.

All 757-300's have double overwing hatches (total of 4). This isn't even an option. The -300 was designed to have 4 overwing exits plus the dual type-2 exits aft of the wing.

SQ was the first carrier to order the 10 exit config, while the early 757 customers(BA, EA, RC, NW) ordered the 8 exit layout. But the number of exits have no bearing on the etops certification. They are mandated by the FAA/CAA to have an exit for every 60 passengers, and that the aircraft must be able to be evacuated in 90 seconds or less, to gain airworthiness certification. The only requirements for ETOPs in communication equipment, survival equipment, crew reliefs in the FD, and fuel/system requirements. If they don't have the sufficient number of these articles, then extended overwater ops aren't an option.

The 5500-series aircraft were ordered before the 757 was proposed as an overwater aircraft, which was one of the reasons the 757 was never equiped for overwater use by NW up until the last few years. The 5600-series aircraft, that were ordered in 1992, delivered in 1995-98, were also equiped with the option of adding the addition HF radios needed for ETOPs. But Max, not all of the 5600-series 757's are able to be ETOPs qualed, (the last 7). 5636-5649 are the only ones that were delivered with the partial ETOPs provisions. 5650-5657 were not. Can they be converted? Maybe. Will they, probably not. They can, however be used on the Interport-Asia, as these are not ETOPs routes.

I'm not sure exactly what you're trying to say here. The slide being inside the cabin would indicate a type-II exit. The 757's with 4 overwing type-III exits have the slide housed in a compartment on the outside of the fuselage, it deploys off the back side of the wings. That pic doesn't look like a 757 interior to me??

No Delta was the first customer to specify 2 overwing exits on their 757s when they placed their (then) record-breaking order for 60 757s in November 1980. It was nearly 3 years later when Singapore Airlines and Northwest placed their initial 757 orders, and nearly 5 years til Republic placed theirs!

The 757 was fully overwater-capable when Northwest placed their inital order in 1983, just Northwest chose not to configure their aircraft to take advantage of that. ETOPS is a separate issue, so are HF radios! Having dual HF radios was an option on the 757 from day one, but not having them doesn't prevent you from operating ETOPS sectors - for example if your ETOPS sector was overland as in parts of Africa and Asia HF radios may not be required. ETOPS capabilities came later, but again as it stands Northwest's 757-200 fleet are not ETOPS-capable because that's how Northwest wanted them.
