You accelerate to whatever speed you want to climb or descend at first and then you press LVL CHG.

I never saw this behaviour in any PMDG boeing plane, i believe but need to check

June 16, 2025Jun 16 Ok but I mean the resetting of the speed of the MCP to from 150 to 9 I never saw on a PMDG plane when pressing LVL CHG But will check after my flight in the PMDG 777 Also the lowest selectable speed on the MCP is 100 normally Edited June 16, 2025Jun 16 by rob0203

Whether this happens or not is irrelevant. Level Change is not a mode to be used before take off.

Level Change is not a mode to be used before take off. I like my simulation as real as possible, so this seems not correct behaviour. So it is relevant for me...... Anyway I also asked at Ifly let's see what they say! For me it is quite weird to have your V2 speed reset from 150 to 9 on the MCP and could be possible quite dangerous.

That's exactly why you don't arm LVL CHG on the ground. For the 10th time now. You set it at Flaps Up. Not earlier. Edited June 16, 2025Jun 16 by Farlis

It can only be selected as an active mode. Think about it: level change is a command to climb or descend at a given speed, which defaults to present speed when pressed. Because of this, you will never select level change on the ground. Because what is it supposed to do? It cant climb or descend. But yes, it'll probably reset your MCP speed to present speed, or as slow as it's able. I'm not positive what value it would choose as I've never tried it, because it won't work. There are two vertical guidance modes you can choose - TOGA with VNAV armed, or just TOGA with some manual intervention after the fact. Yes, you'll set V2 in the MCP. If you arm VNAV off the ground (the recommended method), speed schedule during cleanup is managed for you. If you go off in TOGA without VNAV, you'll have to select a vertical mode when it's time to accelerate. But you'll never select level change on the ground. I've never tried it in the PMDG either, but if it lets you and doesn't change your speed, then that's a PMDG error. Andrew Crowley
June 16, 2025Jun 16 Thank you for the detailed explanation, I understand the function of Level Change and what it does in flight. In different planes it has a different name. Still is the question is it correct that the Ifly 737 MAX selects a speed on the MCP which is under the minimum selectable speed of 100 kts on the MCP? You can normally not dial a speed lower then 100 on the MCP. The PMDG I tried it adds +15 knots to the displayed speed Maybe a but nerdy discussion but what is right?

It definitely should not add any speed, but should default to your current speed. If you're doing 15kts over displayed speed, then yes that would be correct. Otherwise no. Andrew Crowley
June 17, 2025Jun 17 Not a great start. First flight and MSFS froze. Don't remember the last time that has happened. Ron MSFS 2024 -Too many airplanes to name. Too many airports to name.

I would think this is not correct behavior, no matter how wrong the actual input might be. cheers, NiIs U.AMD 5800X3D | 32GB DDR4 RAM @ 3200MHz | RTX 4070 12GB @ 1920x1050px

All it means in this case is that you pushed that button. The lights in the MCP buttons are not your indication that any mode is armed or active. The only place to reference armed or active modes is the (aptly named) Flight Mode Annunciator, the row of inscriptions across the top of the PFD that shows active modes in green and armed modes in white. Unless you see an autothrottle mode of N1 and a vertical mode of MCP Speed shown in white, level change isn't armed. You'll never see that because level change CAN'T be armed. I do suspect that the MCP speed window would probably default to 100A if you did press it on the ground... I'll try it later this week. But I'm not sure it's worth worrying too much about what the sim version of the plane does in these edge case conditions that would never happen anyway. Andrew Crowley
