707 Engine Starts

Seeing as the 707s lacked an APU, would an engine be started at the gate prior to pushback after the ground power unit was disconnected?

Hi. Yes the Eng would be started at the gate, and when the Engine came up to idle the power would be trasfered to the eng and the ground power removed ( can't remember if the Gen had to be sync'd like the 727 but I guess they did ). Now I have seen both, all four started at the gate, and 2 started at the gate and crossbleeded. The reason I liked starting all four at the gate, was if they push and had a problem we would have to drag them back to the gate. You start all 4 at the gate and you saved your self a headace. I know Western sold some 720B's that were modified after it left with the APU. It was in the fwd side of the aft cargo pit. I would think the 707 mods were the same due to the size of the APU would take up. BTW the eng start was the same with the DC-8 with out APU's. HAL use to gate start the 8 next door to us in HNL. HTH
