New generation aircraft with EEC's will not exceed engine limiations when throttles are "fire walled". The EEC provides N1 and N2 redline overspeed protection in both normal and alternate modes. The EGT limit must be observed by the crew because the EEC does not provide EGT redline exceedance protection.

A good question with equally good answers.

Serious prangs
Well the two engine brigade are not immune at all. Most of their encounters leading to accidents have been non-fatals.
There can be a loss of lift on some aircraft during gear retraction as there is a positive pressure in front of the gear legs. Watch out for your autopilot modes when going through the encounter. It is not unknown for Control Wheel Steering to drop out and the crew not know. |
Windshear Related Airlines Accidents Source: FAA, NTSB Records, & Fujita Year Flight Number/Location/Type Injuries Deaths 1956 BOAC 252/773, C4 Kano, Nigeria 11 32 1974 Pam Am 806, B707 Pago Pago, 96 1975 CONT 426, B727 Denver, CO, 15 0 1975 Eastern 66, B727 JFK, New York 12 112 1976 Royal Jordan 600 Doha, Qatar, B727 15 45 1976 Allegeny 121, ???

Yes indeed of the 9 fatal accidents involving Jets (according to this table), only six of nine were tri-jets, interestingly the other three were rear eng MD-82, DC-9 and IL-62, a couple of other non-fatal "fender benders" I couldnt find info on without spending the afternoon on Google. The point I was obliquely making is. For SE certification 2eng aircraft have more excess thrust available, thus enabling them to more adequately deal with windshear, it appears this may also be a factor for the rear mounted eng machines ?? PS; table didnt format into post.... sorry about list length |
