am going to try and build a glide slope indicator on a hud.useing bitmaps, gathered from posts that vectors are power hungry and since my codeing is beginner in-effeiceint..nuff said. the parameters i need are ?A:NAV HAS GLIDE SLOPEA:NAV RADIAL ERRORA:NAV GLIDE SLOPE ERRORam i missing any Vars? and hoping someone might post a snippet or 2 to get me started. thx in advance.unrelated to above;Jan

A:NAV1 GSI,number returns: value -119 --> +119 (= deviation from the glideslope)And the "Jan" as in "f16ko" effect is Jan Rosenberg ("JR") Cheers, ROb

ok thx..i knew Jan's from f16ko last name, but i did not know if it was the same jan that post's here as 'phjvh'
