When REX decideds to stick a hot rod down my throat by downloading weather during my approach from about 20m visibilty to 1m I need help figuring out the glide slope. When the airport does not use ILS is there any way to have a glide slope if you cannot see the PAPI lights. It is frustrating always changing the weather making it unrealistic. So all I need to another glide slope option other than the PAPI Lights when I cannot see anything tan a mile foward.

Hi DANEQ99,

 

First, just a friendly reminder that you must sign your full name at the bottom of your post (or put it in your signature) when posting in here.

 

Now to your post;

 

If the airport doesn't have an ILS facility, there is most likely a chance that it will have some sort of other non-precision approach (NPA, especially if its capable of taking a 737 or larger aircraft): These can vary from a NDB approach to a RNAV (GNSS) approach. The easiest way to find out if has these is to go to your FMC DEP/ARR page and check out what approaches are available (Or if you have access to charts use them).

 

Lucky for us, and I will assume you are flying the NGX (although most other aircraft have similar features, just different ways of using them), the NGX is able to fly NPA's with a thing called Integrated Approach Navigation (or IAN). So basically, if you have loaded up the approach into the FMC (for example, the RNAV (GNSS) 35 approach), you are able to press the APP button on the MCP, and you will get a lateral and vertical scale show up on the PFD, similar to what happens when you have an ILS tuned in! The aircraft will then show FAC and G/P in the FMA and will follow the published procedure, where the pilot will terminate and continue visually to line up with the runway and land.

 

Now you mention the visibility reduced to 1mi. Unfortunately most NPA's will have a visiblity requirement that is larger than that, and therefore you cannot shoot the approach. In that situation, I suggest you either;

 

( a ) Go around and hold in the vicinity of the airport and wait for the weather to clear

( b ) If you planned for an alternate, divert to that said alternate

( c ) Clear REX weather and continue as you would of before the weather rolled in.

 

Hope this helps you a bit.

Use active sky it seems to smooth things out a little better than Rex does

Yeah I agree, I have found the REX weather engine to be probably the worst out of the 4 main ones available.

 

My order of preferences for weather engines are; Opus, FSGRW, AS and then REX.

 

It probably isn't a good thing to use the REX weather engine if it is degrading your visibility from 20mi to 1mi in that quick of a transition.

Doctor: "Stop doing that."

Hello,

 

if you are using NavData Pro, I believe it has the RNAV RNP approach in Innsbruck. That has cosiderably lower minimums than the usual localizer approaches, and puts you on final over the town. Maybe you could use that.

If there is no ILS, read current metar and judge if you can perform a non precision approach, then fly to the MDA and see if you can land or not.
