Here's a true story. Yesterday my dad walked into the room while I was mapping the Second Officer's panel flows from the FCOM onto the free X-Plane DC-10's FE panel. He was intrigued and asked "are you playing snakes and ladders?!"

I told him it's the Second Officer's panel flow ... but on second thought, it really did look like a game of snakes and ladders!

Attached above is the diagram for reference ... the actual scan path they took.

If anyone's curious to see this flow in motion rather than just as a diagram, I mapped the whole thing.

I figured the visual scan path might help it click for people the way it did for me.

The Second Officer's panel flow on the DC-10 is genuinely interesting once you see it laid out.

Starting top left, descending through the electrics and hydraulics panel, cutting right across to the fuel panel, then up to pressurization, pneumatics, fire panel, and so on ... all while performing memory items and checks along the way.

A couple of checks stood out to me as particularly clever

Hydraulics: Pressurize Aux Pump 1, verify lower rudder centering (if deflected), then pressurize RMPs 2-3 and verify lower rudder centering. Finally, 1-3 while verifying the appropriate SO's annunciators and pressure rise.

Fuel: Latch on Pump 3 for each tank and verify 20 PSI, then unlatch. Latch the transfer pump, open the crossfeed for each tank, and verify 20 PSI again. If fuel is present in the AUX tank, latch AUX tank pumps and open the No. 3 crossfeed and verify around 15 PSI for tank 3.

Anyway, my dad still thinks it looks more like a board game than an aircraft system, and honestly at this point I can't unsee it either. Happy to answer any questions and delve into the DC-10 FCOM on the flow if anyone has any questions.

That sounds like waaaay too much work for me!

FJS 732 is much better suited to my simple brain 😂

:) how are you finding the xplane 12 FJS 727?

Still in xp 11 (for that and the TBM!)

Certainly better than the flow on Concorde, which isn't much of a flow at all.

Interesting. Will have to map that one out soon :)
