I mostly just press [K] and plane comes to stop. But I am curious to learn how or why systems on the jet are implemented the way they are.
Eg. this recent thread had me wondering “why” this switch exists…
https://forum.falcon-bms.com/topic/22972/4-36-master-caution-light-comes-on-when-lowering-the-lgI certainly appreciate the improved fidelity in the sim, of course. This seems like a very specific detail – what is the underlying rationale – why is brake channel 2 powered during flight but not brake channel 1? (Should we always be switching to ‘2’ before lowering the LG?)
There’s a diagram in the manual explaining how the 4 FLCC branches map to the left and right brake pedals, based on the channel-switch … but again I wonder why. Almost nothing else in the jet is mapped out to different FLCC branches like this, or offers an override switch to select which FLCC branch to use. And why would individual pedals (L/R) be mapped to different FLCC branches?
Honestly I’m not even sure I understand why the Flight Control Computer would have anything to do with the toe-brakes, or vice versa.
And does brake-channel 1-2 relate to the hydraulic lines A-B in any way?

@airtex2019 It mostly is relevant in case of emergencies. If you are limping home in a shot-up jet, (random?) failures can occur. Among those are landing gear problems. The 4.35 checklists are still valid, section 5 details how to get the landing gear working in that case

@jayb I definitely appreciate the likelihood of hydraulic failure – learning (and practicing) that checklist, and the alt-gear release process is important.
But wheelbrakes and their interdependency on the FLCC’s are weird. I wonder if other late-cold-war era fighters are the same, or if it’s a quirk of the Viper.
I sometimes have to remind myself that in 1970 those “FLCC” units were probably a lot bigger than my smartphone and a lot more fragile. It’s telling there were 4 of them. (Still true in the modern blocks? I wonder.)
