Go-arounds
Yes, the One-Eleven-500 (the stretch) was ill-suited to operate charters out of Spain to the UK in the summer. Using the Spey’s water injection increased the RTOW by less than 400kg, IIRC, and meant loading about 120kg (?) of de-mineralised water. Overall improvement in available payload: 2or 3 pax. And after my time they even throttled it with a useless hush-kit...
TTex600,
Earlier on this thread we were discussing go-arounds, and the natural pitch-up tendency of aircraft with under-slung jet engines as G/A thrust is applied. (This tendency is, as you know, eliminated on Airbus FBW a/c in pitch-normal and pitch-alternate laws, but not in direct law.)
The 1-11 and its big brother, the VC10, gave little pitch-up because of their tail-mounted engines. Can you comment on the DC9, and if possible compare it with any under-slung jets you’ve flown with conventional flight controls?
