The abundance of power in the VC10 was great to have up your sleeve in a possible emergency.
During the days of BOAC VC10 ops out of Nairobi, (5300ft.) we even had an emergency clean up procedure to cope with the unlikely event of a double engine failure, shortly after take off, Northbound to Europe.
Practiced in the Sim, I don’t recall it happening for real. I can’t remember the exact details, but it involved splitting the flap/ LE slat lever, ( They normally retracted together) and at a suitable speed firstly retracting the flaps and after further acceleration, the slats
This procedure was combined with an emergency terrain avoidance routing too, which continued with the early B747-100, which didn’t climb that well after an engine failure out of Nairobi, at the heavy weights departing Northbound.
