Good to see some re-hash of a few things, especially the AoA issues.

As far as the pilot actions go, all we know is what the pilot did. Until we all join him in that hootch bar in the sky to get...

Only problem I have with your "analysis", Doze is that the jet flies like all the rest.

That is true if all you want to do is have auto-trim corrected for pitch attitude, roll limiting to 30 deg...

My aero understanding and actual college courses and actual flying with AoA indicators tells me that the "stall" or max L/D is pretty much the same as long as you don't...

Good thots, OG.

To be honest, I don't know when the Viper FCS ignored AoA or didn't. Best I have in documents is that it was used as long as we had WoW switch decompressed. When I did a tail...

As a matter of fact, our pioneer FBW system did not have a stall or AoA warning.

We had a "slow speed" warning based on aero data if below 120 knots with gear up. Otherwise nothing. The limiters...

Back to the future one mo' time

Doze has iterated the basic concept of FBW.

Where application/implementation problems come into play is how much "protection" is included in the software or hard-wired analog systems we had in the...

Salute!

Fer chrissakes, we are back to the basic design and such of the magenta line jets and the associated autopilot modes and their connection with the FBW systems or even the old systems.

Attitude, flight path, AoA, displays

Guess we folks from another career field have lost the battle about an AoA indication ( a simple one). Same for a HUD.
