Jan Naslund Posted October 28, 2017 at 10:56 AM Posted October 28, 2017 at 10:56 AM Hello everyone, I have recently changed from flying mostly FSX PMDG 737-800 to flying xplane 737-800 (Default aircraft). I have noticed quite a lot of differences but one big difference is the landings. I have landed at the same airports with the same ref speed (138 kts) and in the FSX PMDG the percieved speed at landing is much higher and i always had to use reverse trust and brakes to not overrun the runway. In the xplane11 the perceived speed over the runway is much slower and i never have to use reverse trust as i don't need it. I dont even have to start braking immediately after landing, i can let it roll and lose speed before braking. No problems with runnning out of runway. Has anyone else noticed this and which model is more true to the "real thing"? Best Regards / Jan Link to comment Share on other sites More sharing options...
Trent Hopkinson Posted October 30, 2017 at 01:00 AM Posted October 30, 2017 at 01:00 AM 4 real world videos of 737-800 cockpits where the reverse thrust is deployed within a second or 2 after touchdown.

Jan Naslund Posted October 30, 2017 at 01:25 PM Author Posted October 30, 2017 at 01:25 PM Thanks Trent for the videos, The feel of speed over the runway look more similar to the FSX landings i do than the Xplane 11 ones. Of course in the last video the approach and landing was performed at a higher than normal speed due to strong winds but the first video looks to be somewhere in between FSX and xplane11. I don't need to use reverse trust at all in the xplane 11. I don't have autobraking set either. After landing i can let it roll and then apply brakes just so i can turn off onto the taxiway. I will try to apply reverse trust only without brakes to see what it is like then. Best Regards / Jan Link to comment Share on other sites More sharing options...
1275389 Posted October 30, 2017 at 02:35 PM Posted October 30, 2017 at 02:35 PM (edited) I will try to apply reverse t[h]rust only without brakes to see what it is like then. Try turning on the autobrakes and applying reversers normally. Edited November 1, 2017 at 12:09 AM by Guest Link to comment Share on other sites More sharing options...
Robert Shearman Jr Posted October 31, 2017 at 10:51 PM Posted October 31, 2017 at 10:51 PM I have landed at the same airports with the same ref speed (138 kts) and in the FSX PMDG the percieved speed at landing is much higher and i always had to use reverse trust and brakes to not overrun the runway. In the xplane11 the perceived speed over the runway is much slower and i never have to use reverse trust as i don't need it. Just to be sure no other variables came into play, were the simulated headwinds and air temps similar in your test-cases? Headwinds and cold temps would slow your groundspeed even at the same Vref in terms of KIAS. Cheers, -R. Link to comment Share on other sites More sharing options...
Jan Naslund Posted October 31, 2017 at 11:07 PM Author Posted October 31, 2017 at 11:07 PM Hi, No, not all parameters affecting the landing experience were the same. I am fairly new to xplane 11 and i realized that i might not have the same landing weight in xplane as i have in FSX. So to test this i set max weight on the aircraft, made a 1 hour flight and now the roll-out distance was quite much longer without reverse trust. I made another flight with max weight and this time i applied reverse trust at touchdown and now the experience were more similar to FSX. Thanks everyone for your input on this. I learn new things every day Best Regards / Jan Link to comment Share on other sites More sharing options...
Thimo Koolen Posted November 1, 2017 at 06:57 AM Posted November 1, 2017 at 06:57 AM Also a factor is a professional-ish 737 addon or a 737 plane that came shipped with xplane. I bet the first one would be more accurate anyway ACCNL4 (Training Director) - Dutch VACC Link to comment Share on other sites More sharing options...
Robert Cardone 1323915 Posted November 1, 2017 at 11:02 AM Posted November 1, 2017 at 11:02 AM The flight model in the default 737 in XP is pretty bad compared to the PMDG 737. Link to comment Share on other sites More sharing options...
Luka Stevens Posted November 2, 2017 at 10:41 AM Posted November 2, 2017 at 10:41 AM The flight model in the default 737 in XP is pretty bad compared to the PMDG 737. If you really want to compare I suggest trying it with the IXEG 733. LUKA STEVENS Belux vACC Training Director [email protected] Link to comment Share on other sites More sharing options...
Board of Governors Roger Curtiss Posted December 5, 2017 at 05:56 AM Board of Governors Posted December 5, 2017 at 05:56 AM Use of reverse thrust is standard practice in 737 operations. To have landings where it is not needed would be unusual and could be a result of an absurdly low landing weight. To not use reverse thrust is not indicative of real-world practices so if realism is your goal...

It is all dependent on airline SOPs, runway conditions and lengths etc. Link to comment Share on other sites More sharing options...
