bbarreiros 3 Posted May 27, 2015 Share Posted May 27, 2015 Hello Guys, Ive seen an old thread about this topic but closed now. Ive been trying to fly three RNAV approaches up till today, one successful but two without success. Initialy though I was missing something as in the company I fly for we dont fly RNAV approaches. I revised the procedure again from the normal procedures in the FCOM. I would like to see if anyone have issues with RNAV approaches. Thank you all in advance.

bsal 38 Posted May 28, 2015 Share Posted May 28, 2015 Can you give more details as to what is going wrong? Link to comment Share on other sites More sharing options...
bbarreiros 3 Posted May 28, 2015 Author Share Posted May 28, 2015 Of course. First I believe RNV APP should appear at the top of ND. The FINAL APP become armed when I arm the APPR but over the FInal Descend Point aircraft should start the descend and activate FINAL APP and nothing happens. Is this working properly at your side?

matty260191 23 Posted May 29, 2015 Share Posted May 29, 2015 why arm the APP button? thats for ILS arrivals using a glideslope. your RNAV will have its own decent profile down to Minimums. Link to comment Share on other sites More sharing options...

Hello Matty, Thank you for your feedback. As mentioned above I dont fly RNAV approaches as Ive not been certified for that, all my information is based on FCOM normal procedures and from there you do need to ARM APPR for RNAV approaches. Btw, Arming APPR is not only used for Precision approaches as you mentioned but also used for Non Precision Approaches in case you fly both profiles managed. Thank you.

Emi 5161 Posted May 29, 2015 Share Posted May 29, 2015 why arm the APP button? thats for ILS arrivals using a glideslope. your RNAV will have its own decent profile down to Minimums. That's only correct for Boeing aircraft, in Airbusses APPR activates the approach mode for all kind of approaches. Just like Boeing does with LNAV/VNAV in Airbusses there is FINAL APP mode which will follow the profile below the selected FCU altitude. It's comparable to IAN approaches in a 737 if you're more used to Boeing aircraft. No one is having the same issues? RNV APP is an indication by an older Airbus software revision. In the one we model it should display RNAV xx (xx being the runway number) if I'm not mistaken. I didn't have problems flying RNAV approaches so far, but I'll do some checks over the weekend.

Deputy Sheriffs The Dude 6537 Posted May 29, 2015 Deputy Sheriffs Share Posted May 29, 2015 Basicly the same as this thread: (also started by you) http://forum.aerosoft.com/index.php?/topic/95269-non-precision-approach-managed/ Fully managed NPA's are flown the same as RNAV's. ps, the bus has RNVxx in it's ND. This has already been forwarded to the dev to be changed. Link to comment Share on other sites More sharing options...
bbarreiros 3 Posted May 29, 2015 Author Share Posted May 29, 2015 Hi Frank, Thanks for your feedback. Ive decided to open separate thread since RNAV and fully managed NPAs are different approach types that require different minima criteria. For example the minimum GPS accurancy needed is different. Also for managed NPAs you also confirmed sometimes it doesnt work at your side and I believe the developers are investigating. Does this mean you also got problems with RNAV approaches? Thank you so much for your time. Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted May 30, 2015 Deputy Sheriffs Share Posted May 30, 2015 Hi, the approaches are the same from a procedural point of view but it is a good thing to post the issues seperate. Sometimes they work for me, sometimes not. I did not find out what causes the unusual behaviour. One important thing is that the FAWP has to have an altitude constraint and you should be at this altitude when overflying it. Be aware that fully managed approaches are not "fully" modeled in this product due to, among others, the database that is used. This database has not all the data needed for a 100% realistic simulation. One of the items missing is the vertical profile between the FAWP and the MAWP for example.

bbarreiros 3 Posted May 30, 2015 Author Share Posted May 30, 2015 Ok clear. So its not only at my side that these approaches doesnt work sometimes. Understand also for fully managed NPAs that some profiles are missing but the ones I tested Ive matched against real Jeppesen charts to make sure the profiles are there. Ive not even created the profiles myself as in real life you are not allowed for that in a fully managed approach. Would also be intrested to know what are the developers looking forward on this issue and if there is space for improvement in a future release. Thank you once again for this product which Im very happy with, just trying to make it better and better. Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted May 30, 2015 Deputy Sheriffs Share Posted May 30, 2015 You can not enter a vertical profile in this product and also not in the RW. I am not talking altitude constraints here but "slopes", like 3 degrees with a standard ILS. As a real Airbus pilot you should have noticed the missing line in the MCDU FPLN pages. I also talked to the dev and almost nothing can be done here. Link to comment Share on other sites More sharing options...
bbarreiros 3 Posted May 30, 2015 Author Share Posted May 30, 2015 Yeap indeed have noticied that. It was definetely the first thing I saw missing when I performed the first NPA when was fixing the VAPP at the FAF. Ok I understand you guys can only do what can be done.
