I experienced this for the first time as well the other day. However, I was on approach to MMMX (Mexico City), still turning to the IAF. I had the ILS tuned, but had not activated the V/L or LAND buttons. I was in the bank from VOLUN to MX901, when it started bouncing up and down. It finally settled down on its own in time to arm the ILS modes and land properly. Turbulence on low, PROF armed, no traffic around me (late at night), no visible weather changes.

I use MK Studio V2 EIDW. I swear I landed there a couple weeks ago in the A300 on 28L, which is typically where I land usually.

Okay, thanks for the update. I have the updated AIRAC from Navigraph in MSFS, I just wasn't sure if there was some way the aircraft itself retrieved this data for the FMC. I didn't have any 28 choices, so perhaps the new AIRAC is bugged. I am aware EIDW has a 28 left and right, I've flown there in real life, and in the sim dozens of times. I do have all piloting assistance options off. If it happens again, I will post a screen shot. Nothing was disarmed or turned off, either from hardware or visually when looking at the panels. Unless a weather change generated some strange data that threw the ADC off.

I was heading from EGLL to EIDW and about midway to Dublin I lost airspeed, dropped into the red, and had a difficult time bringing into a proper airspeed. I had to disconnect the AP and hand fly for a while, descend to FL200 from FL360, then tinker with AP to get it back to cruising normally again. I was not actively engaged with the computer at the time (I was watching YouTube on my iPad). Anyone else seen this type of behavior? Also, is the MSFS NavData the only source of AIRAC? EIDW did not have any RWY 28 selection for approach. Thx, Chris

It's hit or miss from what I've seen

New user, new install. I have no ATC either, only user voice.
