The new WL/PSAS Control dialog WING LVL engages the WING LVL system CWS is active all the time, providing PITCH augmentation, but it's much much improved, and flies alot more natural. You'll never realize it's on until you hear it trimming for you ;) Activating MAN PITCH mode will disable this system and give manual Elevator back to the pilot, this will illuminate the MASTER CAUTION light, as and Pitch Degree Pitch Rate protection, and stability augmentation is no longer available.(edited) Now that I've modelled the engine parameters correctly, without stability augmentation, the pitch can be difficult, especially during approach, when winds are acting up. It's been active for a while, but less noticable. Now it's full authority, and very smooth. I've flown many ILS and Visual approaches now, and it still feels very natural :) This is the most advanced 707 in the world. On approach to the default 2017.1.2 airport manual approach, with PSAS on, following the ITAF FD on the HUD :)
The next autopilot build will feature the option to go into FLARE mode even if the AP is off -- this will be on the KCs, and will guide your through the flare if that's more your style :) I'm very excited about this new technology, and I can't wait to show it off to you very soon!
FAQ: Q: PSAS is crashing my plane!!!! A: Open Leveller/Pitch Stab settings from KC-137R menu, push MAN PITCH
Now note your IAS, attitude, altitude, flap setting Now go DEBUG --> Property Browser go to it-fbw and tell me the value of pitch-deg Otherwise, I can't debug and fix the issue This system is built as a deritive of IT-FBW system which has just revamped, so I can say it works 99% of the time
