IAS loses control.

Post by TJ Turner » Fri Mar 31, 2023 8:30 pm

I'm in the CFM variant with the Delta Airline livery. I'm on the Xbox this time.
When flying IAS, the plane will hold it's speed with in the cockpit, but when switching to external view, the plane will accelerate to overspeeding.

Also do the IRS Align switches actually do anything?

PS>Please clean the bird do-do from the cockpit windows. Its gross.

to hold speed accordingly you need to place the throttle in CLB mode so auto-throttle is activated.

I'm well aware of that. The problem is that the IAS doesn't hold in external view. I haven't flown the Asobo plane recently so I don't know if it's a problem from that, but I've never experienced it until I flew the A320ceo.

you got to be careful because if you move the throttles you may deactivate auto-throttles.

Here is a video I made of the issue.
I'm not doing anything different from any other Airbus. Auto throttle remains on and even returns back to the correct speed after going back in to internal.
You can see I'm holding 240 kts in IAS. When I switched to external view you can immediately hear the engines ramp up, and when I return to the cockpit the speed was increasing towards 260 kts.

Here is the Youtube clip of the issue.

It seems like a very strange issue, we will examine this and check if we can replicate it.
Question can you try the same situation on the default a320neo?

Neverminded, I figured it out. Somehow Auto throttle got bound to the same button I use for external view so switching to the exterior view was also disabling the auto throttle. :D
