Hi Mutt,
Why not use extended second segment and climb to 1500 feet before accelerating?
We started flying some old 707s on short haul charter routes in the 70s. The previous operator of these aged aircraft had "trained" our new trainers to use 1,000 ft agl Acceleration Altitude everywhere. When our performance people looked at the available weights out of certain airfields with terrain problems, they produced performance tables with raised AAs so we could increase our payloads.
The previous operator had never considered raising the AA.
