411A,
Do you do reduced power takeoffs?
Yes, using the assumed temperature method, as approved by the regulatory authority, and the specific aircraft/engine manufacturer.

And, oh by the way, bringing B737 aircraft into the discussion has absolutely NO relevance to the subject, because...a B737 was NOT involved in this incident.

By your logic we should backtrack a Twotter which typically operates out of ISC with only 1870 feet or even the Maule which gets off the ground in around 200 feet from my local 750 foot farmstrip.
No significance to the present discussion, IE: not the same category, as is the above mentioned B737.
NONE.

British Airways policy, by condoning the use of intersection departures with the B777, set themselves up, hook, line and sinker...for trouble.
And, they found it.

"At many of the Caribbean Airports that we operate to, a full length departure means a backtrack (or Back-taxi if your American). Whils't that is not a big deal for a shorthaul/narrowbody aircraft, it is a big deal for a 777 which cannot turn 180deg in a standard rwy width (45m). There are turning circles at the end of most rwys, but a 180deg turn in a 777 is a convoluted affair (BA/Boeing SOPs) with a 15deg offset required, a full stop, hard tiller over and then turn into turning circle using outboard thrust. Apart from being slow and inconvenient, it tends to wear the rear tyres quite badly, especially if the rear wheel steering is U/S."
Adequate width runway turning bays existed at the airfield under discussion, therefore, the above quoted 'explanation' is totally without merit.
