Hi all,

So, in an effort to add the ILS approach altitude to as many airports as I can for PF3, does anyone know where I can get accessible charts? By that I mean, can I get the charts in PDF form without any kind of graph or image, just the text information? For example, the elevation of a runway so that I can calculate the FAF altitude for PF3 on it's airport page.

I can't just load a flightplan and go with PF3, as if I follow PF3 instructions to the letter I can't get the glideslope by default. I wonder if this is something Its your plane does, but all that does is help me follow PF3 instructions as a blind simulator pilot.

This post, then, is mainly asking about accessible charts. Also, is it possible if an update can be released where the possible options for FAF altitude etc can be placed into combo boxes/drop downs? For a screen reader user, the scroll bars can be quite a pain to change, and I don't even know for sure if I'm changing the right scroll bar for FAF altitude.

Thanks!

I have increased my FAF distance to 9NM, too, and the problems I had before that have vanished completely.
I'd say the different FAF altitudes are only important for flying into airports that are located in a valley.

7nm works well with an FAF altitude of 3,000ft agl. In this example the faf is set to 4,000ft QNH only because it is in reality 3,000ft above ground level. fafx.jpg You should always enter the FAF altitude given in the charts as that is set at QNH. Take the FAF QNH deduct the airport elevation, divide the result by 3 then divide by 100, then subtract 3 from the result.

e.g. EGLL
FAF QNH 2,500
less arpt elev 80 -
= 2,420
(2420/3)/100 = 8.07
8.07-3 = 5.07 rounded to 5
Therefore for London Heathrow set FAF to 2,500 and FAF distance to 5.

e.g. LIMF
FAF QNH 4,000
less arpt elev 989 -
= 3,011
(3011/3)/100 = 10.04
10.00-3 = 7.04 rounded to 7
Therefore for Turin set FAF to 4,000 and FAF distance to 7.

e.g. LOWI (Innsbruck has a 4 deg slope)
FAF QNH 9,500
less arpt elev 1,900 -
= 7,600
(7600/4)/100 = 19.00
19.00-3 = 16
Therefore for Innsbruck set FAF to 9,500 and FAF distance to 16.

e.g. VQPR (n/a) !!
