After some extensive reading up on my United B707 AOM, I fired the Virtual Flight Engineer and decided to do everything myself, which I found rather rewarding !

I made a solo workload flight and systems explanations tutorial.

In particular I found the pressurisation system very rewarding to learn

Excellent and thank you for the video. Most enlightening. You obviously have a lot you can provide this community and I hope to see more of your insights soon.

Thankyou for your kind words. I enjoy diving into the details of aircraft systems and procedures. I never get tired doing so. :)

As a 21 year old I went flying in a BOAC 707 sitting in the jump seat while various Captains went through stalling exercises.

Although we lost altitude the whole thing was quite benign less exciting than my Cessna 150. This seems to be modelled as I remember it.

These were Captains of Pratt and Whitney 707s converting to the Rolls Royce version and boy what a hash they made of the landings on Prestwick's runway 13. Clearly a change of engine made a big difference to handling.

That is indeed strange. Very interesting. Thanks for sharing your 707 experience :)

Here's another FO tutorial:

This young fella is good. Very very good! I hope he gets a lot more exposure.

Very kind of you to say so. I enjoy doing these. Hope a DC-8 arrives to msfs one day :)

Yes, the Michael Cependa / Aerosoft-published DC-8-50 would represent well in MSFS. Playing FE was kinda fun, operating fuel pumps and buses and all sorts of stuff. I felt like the Wizard of Oz behind the curtain.

Haha. Very true. The DC-8's fuel system is pretty cool. 10 tanks in the aerosoft one !

It's interesting also that the 707 has crossfeeding, but the DC-8 has crossfeeding and tank to tank transfer...

Yes. That's right. DC-8 would transfer fuel on longer flights. I'm not familiar enough with the 707 to know if in the real world they only ever had crossfeeding, and not tank to tank xfer. I'm assuming they only had crossfeeding real world and that this one is reasonably faithfully modelled?

Yes, the 707 relies on crossfeeding only. It's definitely modelled in this addon. The centre tanks are like override pumps and lateral balancing by feeding two engines off a single tank is possible, too. :)

Indeed - the center tank boost pumps ARE literally override boost pumps -ie, they have a greater psi output than the others. This is so that the fuel from the center tank may be used by all engines at the same time, which is how the fuel panel is set up after takeoff if there is fuel in the center tank - that fuel is burned first, prior to burning from the main tanks. All of it.

Interestingly in the 707 manuals I have, depending on the route and certain factors, there are a few ways at which fuel management is approached - even something about leaving 7000lbs in the centre tank which I find confusing 😁
