Feb 20, 2021 · Either case presupposes that the aircraft’s flaps can be lowered completely; even if an aircraft has inflatable overwing slides, these are still designed to deploy over the lowered flaps (a slide designed to deploy over retracted flaps would trail on the ground with the flaps down, impeding egress from the bottom of the slide), while, with ...

Jan 16, 2021 · The DC-10 / MD-11 family has overwing evacuation slides that go over the leading edge of the wing, as do some A310s, making these, so far as I am aware, the only subsonic airliners without engines right behind the wings to use leading-edge overwing exits.

Jul 4, 2019 · Another reason overwing engines are not favored for passenger planes is that instead of shielding the passengers from engine noise by the wing (as in the case of underslung engines) you have the noise source (s) on the same side of the wing as the passengers, which makes for a noisier cabin. In addition, suspending an engine on a pylon under the wing allows the engine to be shed off by gravity ...

The McDonnell Douglas DC-10 and Lockheed L-1011 are wide body "heavy" aircraft with all door exits, no overwing window exits. Mid fuselage doors were built into these aircraft to provide multiple points of entry and exit to speed up normal passenger boarding and deplaning, not specifically for emergency exit efficiency.

When looking at the following Transavia B737 safety cards, I noticed that after a water landing, passengers who evacuate via the overwing exits should leave the wing at the front, while during evacuations on land they should leave via the rear side of the wing.

Nov 14, 2014 · For overwing placement, the opposite is true and you might need a slightly stronger pylon and wing-spars? Overwing placement causes the torque on the wing from the weight of the engine to act in the same direction as the torque from thrust, underwing location reduces total torque - though this may not be significant.

Oct 26, 2019 · If the usage of overwing exits become necessary then they can be used in a ditching. In the Hudson landing, they used the overwing exits because the aft exits were rendered useless due to the considerable amount of impact damage received by the aft fuselage of the aircraft. Nonetheless, there are ditching related safety devices in the overwing ...

Jun 28, 2018 · I have a question regarding overwing fueling a Canadair CRJ200. Let's say I was pressure fueling and one of the wings started venting fuel on the ground. The Crew Chief determined that I had to overwing fuel the wings, and then finally the center tank.

This official image from the Aircraft characteristics airport and maintenance planning document for the A319 advertises the A319 as accommodating 156 passengers in a high density layout, this is al...

Aug 5, 2019 · The overwing exits are not supposed to be used unless other exits aren't available. There are also life lines to help passengers when out on the wings, but these were not used.
