ols500 3 Posted September 20, 2017 Share Posted September 20, 2017 Hello, I have been using the Aerosoft airbus for 8months now, so i'm very familiar with the systems and ILS landing however, when i come in for 26L at Gatwick it disconnects here: Please login to display this image. I am at 2000Feet my MAY so i'm very confused why it disconnects, but the ILS works for 8R in Gatwick... Link to comment Share on other sites More sharing options...
Deputy Sheriffs Tom A320 4915 Posted September 20, 2017 Deputy Sheriffs Share Posted September 20, 2017 Can you provide a screenshot of your PFD/ND and the MCDU F-PLN page in that moment, please? Please open the map within your sim, and click on EGKK to get all details displayed. Please post a screenshot of that as well. What navigation database are you using and what AIRAC cycle of it do you have installed? Link to comment Share on other sites More sharing options...
ols500 3 Posted September 20, 2017 Author Share Posted September 20, 2017 Ok I will be able to give you those screenshots in about 1h because I have to set up a flight, also I'm using nav cycle 1709 Link to comment Share on other sites More sharing options...

ols500 3 Posted September 20, 2017 Author Share Posted September 20, 2017 I read another post about MDA but the 2000f is correct for the approach... Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted September 20, 2017 Deputy Sheriffs Share Posted September 20, 2017 The problem you are having is that you entered an incorrect mininum and because you are still in NAV mode the aircraft „thinks“ that you are flying a non precision approach. Due to the AP logic it will disconnect when you are 50 feet below that minimum. Try to enter the correct minimum of 396 feet for an ILS cat1 approach to RWY26L in EGKK and see how it goes.

DaveCT2003 2553 Posted September 20, 2017 Share Posted September 20, 2017 Beautiful catch Frank! I was going to blame it on the size of his Icons... man, those things are HUGE (well, you know, every man should hear that at least once in his life).

ols500 3 Posted September 20, 2017 Author Share Posted September 20, 2017 @Frank Docter Thank you for your reply, your solution sounds good however I do not mess around with the "incorrect minimum" so is this in the approach page with temperature, winds, baro etc?

datguytho 38 Posted September 20, 2017 Share Posted September 20, 2017 Yes. On the approach page enter the minimum at the BARO (in this case 396 feet) if its an altitude. You can look up the necessary minimums at the approach charts. Link to comment Share on other sites More sharing options...
ols500 3 Posted September 20, 2017 Author Share Posted September 20, 2017 @datguythoSo the BARO is the minimum altitude, I always thought it was a backup altimeter reading, ok I will try that thank you Link to comment Share on other sites More sharing options...
datguytho 38 Posted September 20, 2017 Share Posted September 20, 2017 Yes, the BARO is the Decision Altitude (DA). On some approaches, for instance ILS Cat 3 approaches, you use the Decision Height (DH) instead. The value you enter into the approach perf page will be the point at which the GPWS system calls out: "Minimums". At this point the pilots have to make a decision whether to continue the approach.

ols500 3 Posted September 20, 2017 Author Share Posted September 20, 2017 @datguythoOk thank you for explaining, so in the perf page for gatwick only I would enter "396" other airports it would be different. Link to comment Share on other sites More sharing options...
datguytho 38 Posted September 20, 2017 Share Posted September 20, 2017 It's about the type of approach as well. An ILS approach usually needs a Decision Altitude of about 200 feet above the runway. But if you are going for a ILS Cat 3b, you basically don't really have a decision altitude, but a decision height instead. In this case you would use the value 50 for the radioaltimeter. A minimum callout would be surpressed. And when we are talking about Non-Precision approaches, such as VOR, NDB or visual (or any other kind of similar approach) you will have a higher Decision Altitude. On an approach chart you can look up the DA or DH for your approach. Please login to display this image. Link to comment Share on other sites More sharing options...
ols500 3 Posted September 21, 2017 Author Share Posted September 21, 2017 Ok so for ILS the Decision Altitude would be "50" but for a visual it would be "200" or something similar to that? Im very interested in knowing this... Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted September 21, 2017 Deputy Sheriffs Share Posted September 21, 2017 I would suggest that you move these procedural questions to the general section. We even encourage you to do so because many people could benefit from all the information. This being the support section for problems with the Airbus makes it not the ideal place to do some IFR rules schooling. Happy landings! Link to comment Share on other sites More sharing options...
ols500 3 Posted September 21, 2017 Author Share Posted September 21, 2017 Ok I really just wanted to know why my AP disconnected and how to solve but ok... Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted September 21, 2017 Deputy Sheriffs Share Posted September 21, 2017 And you got the answer/solution to your problem from me. Or are you still experiencing that problem? Link to comment Share on other sites More sharing options...
ols500 3 Posted September 21, 2017 Author Share Posted September 21, 2017 I am actually waiting for DatGuyTho to respond Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted September 21, 2017 Deputy Sheriffs Share Posted September 21, 2017 Why? I gave you the answer. The AP will disconnect if it is 50 feet below the minimum you inputted when in NAV mode. What you are asking now goes beyond the scope of your problem. Please fly the tutorial flight. It explaines the minima inputting and how to do it. Like I said the whole theory behind which minimum goes with which approach is beyond the scope of the support forums. We have the general forums for that. People are willing to help you there without tying up support personal from AS. This may sound a bit harsh but everything regarding minima and the use of charts can be found on the internet by investing some time yourself. It will even give you a better learning experience than just asking. So to get back to your problem, do you still experience it when entering a minimum of 396 BARO when flying the ILS26L in Gatwick?

ols500 3 Posted September 21, 2017 Author Share Posted September 21, 2017 @Frank DocterYes It does work, sorry I thought people wouldn't be so harsh about where I posted a question. Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted September 21, 2017 Deputy Sheriffs Share Posted September 21, 2017 Do not get us wrong but this part of the forum is support only. We have AS people that check these forums everyday to answer support questions. If we first have to read through x postings that have nothing to do with support it binds up our limited time and subsequently we do not have the time to give the full support we want. We encourage people to ask questions and to be part of the community. We are only asking to differentiate between AS product support and other questions and post them in the subsequent forums. Good to hear that the problem is solved and have fun flying the AS Airbus! Link to comment Share on other sites More sharing options...
Cheyenne Chief Pilot 829 Posted September 21, 2017 Share Posted September 21, 2017 ols500, it's also about finding the pieces of information other forum users are looking for: If someone else is also interested in learning about approach minima, they won't look for it in a topic about autopilot disconnects. Or, if someone else wanted to help others learning about ILS approaches, they wouldn't do so in a forum section restricted to support issues with a particular aircraft type. Separate topics for different issues, it really helps you and everyone else the most. Link to comment Share on other sites More sharing options...
