Hey guys,
after the atpl, i went to Montpellier (south of France) to do my cpl & ir-me.
i started few weeks ago with the ir and now i'm flying on a single engine to do all the base of the ir (vor, adf, holding, vor app, ils app and so on) and then i'll switch to the multi.
i didnt have any trouble on sim (fnpt2) with the adf because it was with a movable card but on the single engine aircraft, we've an adf with a fixed card and no briefing on it...:bored:
i understood that to find your qdm (well, france habits...), you have to add your mag hdg + relative bearing.
so if i'm on hdg 270 and the adf shows (with the north up) 330 it means that: 360-330=30°, 270-30=240, i'm on qdm 240.
so far, i think it's right, huh ?
but in flight, my cfi asks me for e.g...we're on qdm 210, bring me to the qdm 260...
so as i learned, qdm are increasing, so i'll turn to the left, 30° left on my actual hdg so 210-30=180°, so i'll fly on 180.
The question is: what bearing should I have on my ADF fixed card to know when i'll be on the qdm 260 ? :zzz::ugh:
i'd like just the method because my cfi is confusing me when he explained me :O
the same about the QDR. :ugh:
you are on QDR 310 and you wanna go to the QDR 280.
QDR 310 => 280 : The QDR are decreasing, i leave the station on my left so i'll turn on my left now (because it is QDR), 30° of my final wanted QDR, so 280. 280 - 30 = 250°
i'll then turn to the 250° on my di in order to intercept.
but after that, I'm lost to know what bearing should i have when i'll be on my QDR 280.
one more thing, do you use that ( adf - hebergeur d'image - Casimages.com - (http://www.casimages.com/img.php?i=111022051438906932.jpg) ) to add or substract what is written on the adf to your mag hdg ? or you always add (according to the formula)
thank you guys for ur help if you can make it clear for me :)
