AS355F1, as I recollect. F2 similar...
1. Push starter button, holding lever in shut-off detent (all back/down) listening up smart-like and watching temps.
2. At 15%, holding the button, advance lever to idle detent, monitoring NG and temps throughout start. Starting the C20 relies on a strong battery and good starter/gen, fuel control start scheduling: no modulation, repeat, NO MODULATION- it's fuel on or off.
3. 60% NG, release starter button, establish idle for engine warm-up.
4. Increase NG to 70%, Generator switch "ON", monitor NG and ammeter.
5. Ammeter back into green, start second engine.
That's how I recall PHI's checklist, which is/was safest possible in their opinion.
My recollection is that one could start second engine immediately after first was established at idle, battery permitting. If that's the situation, you let each warm up before you advance to 70% NG and bringing each generator on-line.
Kinda hazy on the F2 other than increased MGTO, tens of thousands of starts in the F/F1 (ending 15 years ago) but only a couple dozen F2, something about a completely split electrical bus, with the normal pair of start/gen buttons, but 2 battery switches?
