austrianairbus 0 Posted August 17, 2015 Share Posted August 17, 2015 Hello,When approaching some airports (e.g. Fuerteventura from Simgiants or La Palma from Aerosoft) the aircraft becomes instable a few moments before touchdown and stops descending, gains about 10 knots speed and i have to push the nose down a few degrees so it continues do descend normally. This phenomenon happens on other airports too when I fly there in the same session without restarting FSX. There is no wind when this happens and default fsx weather is set to "nice weather" (schönes Wetter in the german version). I have version 1.16.This is rather annoying and I would appreciate if someone has a solution for me Cheers,austrianairbus Link to comment Share on other sites More sharing options...
Emi 5161 Posted August 17, 2015 Share Posted August 17, 2015 Hi,does the same happen with other aircraft at the same airports/weather/time? This could be an FSX thermal pushing you up. Keep in mind the FSX fair weather theme is made for soaring! Link to comment Share on other sites More sharing options...
austrianairbus 0 Posted August 19, 2015 Author Share Posted August 19, 2015 I tried it with the default Boeing 737 and the same happens. It would be very weird if the weather does that because it makes a smooth landing impossible. Link to comment Share on other sites More sharing options...
Deputy Sheriffs Tom A320 4915 Posted August 19, 2015 Deputy Sheriffs Share Posted August 19, 2015 Yes, but what else could be the reason, if the same phenomenon happens with two different planes? Link to comment Share on other sites More sharing options...
DaveCT2003 2553 Posted August 19, 2015 Share Posted August 19, 2015 Austrian,Hello again!1. Can you tell us what you're Zero Fuel Weight, how much fuel you have (approximately) and what your speed is going across the threshold? If I had to guess, I'd say that your speed is a little too high (but it's just a guess). The additional 10 knots is likely due to a shallower angle of attack at that particular moment.2. Can you tell us where you obtained your V-Speeds and if you flew the approach using those speeds?3. What was your flap setting?4. What weather engine do you use? I know that's a lot of information, but it will help us to zero in on the problem. Link to comment Share on other sites More sharing options...
austrianairbus 0 Posted August 26, 2015 Author Share Posted August 26, 2015 Hi,1. ZFW is allways different between 43 and 58 tons and the issue is allways the same. Fuel is about 5-8 tons. Speeds are very low about 120-135 knots depending on aircraft weight.2. Speeds are from the MCDU PERF Approach page.3. Full4. FSX default Link to comment Share on other sites More sharing options...
