I tried many times with the A359 model before posting, but everything worked fine after switching to the Boeing model.
The way I operate it is.
at about 30nm from the airport, the altitude is already at 3000ft
maintain speed at around 190 knots
NAV1 of the runway has been set up to activate the ILS.
However, when my aircraft activates ILS, at first the aircraft will adjust its angle normally, but then it starts to shake immediately and continues to shake to the ground (crash), even when I tried to activate APPR at an angle facing the runway, it would shake violently.
However, I use Boeing models with the same operation and there is no problem and the APPR works fine.
I would like to ask if the operation is different because of the model? Or for some other reason, thanks!
Not sure if this will help, but weâre you established on both the localizer and glide slope? Was the VS mode enabled?
A replay would really help too.
I find the A350 isnât great with appr mode in infinite flight. The way I overcome this is by using V/S and heading A/P instead. I adjust my heading to intercept and align with the path and V/S once I reach the glide slope. So Iâm the end I donât use appr on the A350 because in my experience the plane will just rock side to side overshooting the ILS path more and more
Welcome to the community! Try activating APPR somewhere near the beginning of the approach cone with the correct speed of about 180kts and flaps set to 2. Activate Appr when at about a 30 degree angle of intercepting cone.
With APPR, you ideally need to be flying a single hearing when activated and at a single altitude. 3000 AGL works at the beginning of the cone. Try tuning to the ILS first and lining up with the glide slope and localizer (or a heading to intercept the localizer). Or, you can be a bit lower and âcatchâ the glide slope.
Iâd also recommend watch this tutorial from Infinite Flight:
Thanks for your prompt reply
Ya I had both NAV1 and APPR on before I finally landed and just continued to shake significantly before landing with the A359 model, I had no problem operating the Boeing model in the same way.
I think the reason itâs not working is because you have to be 180 knots or below and you have to be at 3,000 or below 3,000. Plus, you have to have NAV1 or NAV2 on. Usually, NAV1. Also you have to be close to the airfield to access APPR. And you have to click on the map the airport icon. Example. Letâs say Iâm approaching KLAX and I want to land on 25L. Well I click on the map where it says KLAX. Then I go to click on where it shows the runways are listed. Then you click on the runway you want to land on. And then, at the bottom right corner, you will see NAV1. Click on that. And your good to go!
The description @MJP_27 just gave is a perfect solution for you and I believe that should work. Just something little to add, I recommend intercepting the ILS at 180IAS, makes it easy for APPR to work and you can gradually slow to Vref as you approach the runway.
@Carolina_Taylor Wouldnât that make the aircraft to bob up and down? Sometimes i notice this issue in addition to aggressive turns into final and localizer route overshooting problems
Yeah, contrary to what @Carolina_Taylor said, you can intercept the localizer at more than 180kts. I usually intercept it before the cone at about 190kts. But what she said totally works too. Itâs kind of up to your preference.
Ideally you can do that say maybe ATC needs a good forward speed. But youâll have to use the VS to maintain the glide slope by yourself, which can be higher than the ideal -700FPM due to the higher speed.
@Crown.plane When you engage APPR, are you not putting any more inputs in? That could be why youâre bobbing, if youâre not manually setting flaps, trim, speed, etc.
Sometimes i intercept at 185 KIAS and still makes aggressive turns when you press APPR and she starts swerving violently⌠Sometimes when you turn into final from the base leg; she doesnât keep the altitude and starts to make aggressive turns trying to get back into the route in right angles
I was asking @Crown.plane what they do. It sounds like you (@Crown.plane) are not flying a set heading before engaging APPR. Did you watch the video I linked above?
This comes back to basic localizer intercepting. When you want to intercept a localizer, you shouldnât be making aggressive turns. You should be on a heading that guides you smoothly onto the localizer and itâll just be a slight turn to final from there. This is what IFATC usually does.
