February 13Feb 13 With iniBuilds having shared their latest L‑1011 development update earlier this week... https://forum.inibuilds.com/topic/35590-inibuilds-tristar-airliner-development-update/ ...I’ve seen a lot of enthusiasm — and also questions from friends who haven’t flown the TriStar before. The L‑1011 isn’t inherently difficult, but it follows a very specific 1970s Lockheed philosophy where systems are highly automated yet still crew‑managed. However, I find aircraft is highly intelligent and a joy to fly in the legacy fsx/p3d. A few areas that tend to surprise first‑time TriStar pilots: 1. Direct Lift Control (DLC) Approaches are flown with spoiler‑based lift modulation rather than pitch alone. With flaps beyond 30°, DLC actively manages panels 1–4 on each wing and will drop out if certain conditions are met (TOGA, stall warning, throttle advance, etc). It’s subtle, but very noticeable when hand‑flying. 2. Engine 2 Takeoff logic (Possibly) Because of the S‑duct configuration and potential surge vulnerability, the No. 2 engine has dedicated takeoff monitoring logic. With flaps in the takeoff range and N2 exceeding ~83%, the ENGINE 2 FAIL ARMED light illuminates, indicating the system is ready to detect a loss of thrust. If N2 subsequently drops below approximately 79%, the failure warning is triggered. Once airborne, the system automatically disarms. This spooked me out first time too haha. 3. Autothrottle ALPHA Protection In TO/GA, or if airspeed decays below approximately 1.3 Vs, the autothrottle system transitions into ALPHA mode. At that point: The IAS readout is covered by an ALPHA flag Thrust is scheduled to maintain angle‑of‑attack, not speed. This is early envelope protection thinking. 4. Pressurization - How to do the ground check ? Selecting Ground check on the rotary is not enough. The system allows the aircraft to pressurize on the ground - ONLY IF a cabin altitude below field elevation is selected. 5. Altitude Capture One small but common trap: altitude capture must be armed. If it isn’t, the aircraft will happily fly straight through your selected level. 6. APU Shut down tip Don't try to turn the APU off via the master power - there's a dedicated stop button used first. For anyone who wants a bit of hands‑on familiarization before the iniBuilds release, I recently put together a TriStar walkthrough using the existing, detailed CS L‑1011 add‑on, aimed specifically at users who are new to the type. The add on is highly detailed and the manual is available here. Captain Sim – 1011 Captain Manuals https://share.google/lzLVOY58gLcdZ7xTz A few helpful, real world TriStar Manuals are also available on the Internet Archive and an in-flight real life cockpit systems tour on JustPlanes. Genuinely interested to hear everyone's TriStar Experiences and how you all are planning to make the most of the new add on when it drops in msfs 2024. 🙂 Cheers, Joshua 757 Aeronautical Engineering Honours Graduate and Enthusiastic Simmer.
