The MD-82
Just once more to clarify two important issues with an MD-82 takeoff in this particular scenario. I have already mentioned this in a previous post.
1. Madrid's runway 36L is 14271' long !
2. Given that length and given a collegues experience taking off from that runway, even at a gross TO weight of about 66 tons (given my personal guesstimate) the MD-82 would have taken of with between 2° and 3° of flaps and a rotation speed of close to 160 knots.
3. It is clear that even so the MD-82 did not even leave the airport perimeter. And that the MD-82 "appeared" to have encountered problems with still a lot of runway remaining.
4. If the crew made a derated TO, they would not have automatic emergency thrust applied as that (ART) system must be OFF when using TO FLEX.
5. Even though they did not have automatic emergency thrust, the ATR system should have set EPR G/A on the remaing engine if it was set below that EPR setting.
6. A quick shove of the autothrottles would have given them emergency power (or even more) if needed as the MD-82 has conventional (auto)throttles.
7. Given the amount of energy they had at liftoff, the MD-82 would have no problem whatsoever in continuing it's takeoff engine failure profile.
8. For an MD-82 travelling at close 170 knots probably, it seems odd that it could not have gotten off to more than 20-50 m height.
9. The crew "appeared" to either have aborted after becoming airborne, or they encountered a deployed reverser at liftoff. Either one a far fetch. Let's hope all becomes clear in this matter.
