August 16, 201213 yr Hello all, Don't know if I am doing something wrong so I thought I'd check with you guys before making a bug report. I decided to try out the default 747/400 in X-plane 10.10b8. Two issues. First is cabin pressure. Or rather lack thereof causing everyone to suffocate. No matter what I do I can't seem to fix this (not that there are that many knobs to turn that could even hope to change this issue...). Second. Pitch oscillations. I set my autopilot to 18000 feet. It climbed up to this level. What began as a small +/- 100 fpm oscillations quickly turned into a +/- 6000 fpm roller coaster. Needless to say my flight attendants quickly ran out of barf bags. I remember I had the pitch oscillation problem with my CRJ200 but it went away (can't remember what I did, apart from the fact that I didn't reset my settings). Any clues? This is driving me slightly insane. Richard 7950x3d | 32Gb 6000mHz RAM | 8Tb NVme | RTX 4090 | MSFS | P3D | XP12
August 16, 201213 yr Were you getting close to the max speed limit, or is autothrottle active? Certainly on the CRJ, if you have altitude hold active on your autopilot, this will be overridden if you continued to accelerate towards the speed limit. In this instance the plane will pitch up to bleed off speed..... then you enter into an oscillation. Whether this happens in real life I don't know. I'd certainly have thought that an intervention on the autopilot would result in an alert of some sort.

This annoyed me to the point of just quitting and go for a ride in the pmdg version of 747 instead... Maybe a bug report is in order. This can't have anything to do with real world behavior of the 747. Sent from my GT-I9100 using Tapatalk Richard 7950x3d | 32Gb 6000mHz RAM | 8Tb NVme | RTX 4090 | MSFS | P3D | XP12
August 16, 201213 yr Have you tried increasing the "flight models per frame" to 2 in the "Operations & Warnings" menu? "Society has become so fake that the truth actually bothers people".

August 18, 201213 yr The default 747 probably doesn't have a realistic FM, it was done just to show the incredible 3d Engine of the X-Plane, not to demonstrate the realistic FM. Alexis Mefano
August 18, 201213 yr Author Yeah, you are probably right. Guess it'll be the pmdg 747 for me from now on... :/ Sent from my GT-I9100 using Tapatalk Richard 7950x3d | 32Gb 6000mHz RAM | 8Tb NVme | RTX 4090 | MSFS | P3D | XP12

August 19, 201213 yr The 777 is due out september 1, if nothing goes wrong on final. If you haven't had a look at it's capabilities, you should. The FMC will knock your socks off! According to some, this will be the premier big iron aircraft to date . This alone should springboard XPX into the spotlight it deserves. Expect to see a lot of people migrate to XPX if the 777 lives up to the hype. Watch Philipp"s final video before the release here
