Hello again Ray and thanks a lot for dedicating your time to me. And don't worry about not having MSFS, It is your experience what is helping us and I have been following you for several days. I will replay by parts if you don't mind. You see Ray, one thing is that it is not modeled in the gauge and another thing is that it cannot be monitored from the developer mode or from other tools that we have, but yes, it does not exceed the VMO of 400 knots according to the Flight envelope (it maintains that speed), up to 36000ft, once it reaches that tropopause altitude it makes a second climb up to 60000ft gradually increasing speed up to 540knots which is when it automatically transitions to max cruise and holds mach 2.04 (which is the conversion from 540IAS to mach 2.04. What I wanted to emphasize to you is that it does not do it through a Vertical speed mode, but rather "Flight level change", in which it maintains this speed by making corrections in Vertical Speed, hence the pitch changes. In fact, if you look at the into the blue video, the plane couldn't climb to 60000ft because currently in MSFS in live weather mode AGL is being used to measure temperature instead of MSL, which means that while at 15 degrees ISA the temperature is -56C at that altitude, he was probably getting -51 (I know because I have reproduced it) while in a normal presset with the temperature at -56.5C, the plane scales perfectly at 60000ft without reheat and gets 2.04 without problem is modeled, MAX CRUISE is coded as a MACH HOLD at 2.04 with the condition of not exceeding 127C of fuselage temperature and reducing speed if necessary (what is not modeled is structural damage due to total excess temperature, it is something that is not supported). Of course, and there's where the confusion probably is: we have implemented IAS HOLD and MACH HOLD according to the manual and based on autothrotle when ON (which are the left buttons of the AFCS), being fully compatible with MSFS in combination with ALT HOLD, VERT HOLD or PITCH HOLD. From what I see, and from your experience I think we agree that the IAS HOLD and MACH HOLD on the right are based on pitch HOLD but with the condition of maintaining a target speed, whether with or without autothrottle. My doubt is if these two commands are based on Flight level change to perform the descent, since if I want to descend at 20000ft at 350 knots Flight Level Change will do it even if the plane applies a vertical speed of -10000ft/min to do so ( as I've seen you mention in another post), but I don't know if it's correct and that's why I didn't want to include it in the release (it's something we're debating right now). My question is, have you used modes to maintain a cruise? or with the objective of climbing or descending? or both? The center console's Autopilot pitch datum system is modeled, and allows you to change the reference pitch, V/S or altitude depending on the vertical mode selected. I thank you very much. It is a living project that we will continue to improve, you have my word. 🙂

Hi Ray, first of all let me tell you that I have registered in the forum with the only purpose to ask you some things that we want to polish in the Concorde (I am the one who helps Dean with the development of the Concorde in MSFS). In response to the question, we simply have not had time due to scheduling issues, but is our intention to include this as soon as possible. 🙂 Also tell you as Dean said, that we have effectively solved the problem of the gauge not displaying the ISA temperature correctly. The questions are addressed precisely by the AFCS MAX CLIMB, IAS HOLD and MACH HOLD functions. If I'm not wrong and please correct me if I am, MAX CLIMB is based on FLC and VMO, this is how we have implemented it and it works correctly when climbing to 60000ft up to 2.04 and altering V/S accordingly to maintain airspeed. The IAS HOLD and MACH HOLD modes on the right are currently covering the functions on the left, because despite having looked at the official manuals there is not much explanation about it. The advisers I have only tell me that it is based on airspeed or mach hold based on pitch attitude, but currently it is not possible in flight simulator if I have set a target altitude with ALT HOLD and the current altitude matches the target altitude. If they are based on FLC we have the same problem unless the target altitude is not the current one, but the use of this mode would fit me a lot if these two modes were designed for climbing or descending in terms of the altitude selected on the rotary selector without using ALT ACQ. Could you give me your vision on the use of these two modes? Thank you and congratulations for everything you contribute to this forum.
