I'm enjoying the new 707 in MSFS! It has certainly been a while since I last operated her in fsx. No wonder when I went to start my engines I made a novice mistake by moving the start lever directly to idle as one would normally do in any other jet. The engine would not spool up.

Then I remembered (with the help of my 707 AOM) that the 707 uses a cam operated start lever with three positions: Cut Off, Start, and Idle. If the lever and the start switch aren't both in the proper position, ignition just doesn't happen.

I made a short video walking through the whole thing step by step since it's a bit fiddly to explain in text alone, if that's useful to anyone else who wants to fly the 707 without the Virtual Flight Engineer.

This is how you start the 707's engines as per the AOM

1.Start order is 3, 4, 2, 1

2.Ground start switch armed first

3. At 15% N2, 'lever to Start', this is when ignition and fuel valve both activate

4. At 40% N2, observe overhead starter switch goes to cut out

5. At 50% N2, 'lever to Idle'

You can then start rest of the engines of No. 3 instead of the ground cart. Its quite a cool process actually.

Nothing like the easy as 1-2-3 in an Airbus or C-525 lol
