protossadun Posted February 18, 2021 Posted February 18, 2021 Hey there, when I turned on ILS approach in A10C II, the vertical line on attitude indicator dose not align with airport runway while the horizontal line works well. What's the problem is that?
Hive Posted February 19, 2021 Posted February 19, 2021 (edited) Hi! Did you set the right course on the HSI? You need magnetic heading! Have a look at these great tables where you can find the values: Aerodrome Data and Frequencies v1.3 BTW this is the forum for the old A-10C, the forum for the A-10C II is this one.

AW139 Posted February 21, 2021 Posted February 21, 2021 You need to turn the Course/CDI knob to match the final approach course shown on the approach plate. Generally it's the magnetic heading of the runway, but not always. The vertical line on the HSI is the localizer CDI (Course Deviation Indicator), and the horizontal line is the glideslope indicator.
Frederf Posted February 21, 2021 Posted February 21, 2021 In the real airplane the ADI steering bar is not connected to the COURSE SET knob. In DCS it is so it's doing a comparison of course set so it's only valid when the course set is set to the inbound course of the ILS localizer. This is an old lack of feature that never made it in the sim. 1
jaylw314 Posted March 1, 2021 Posted March 1, 2021 (edited) On an ILS, turning the COURSE SET knob does not affect the localizer needle (although it changes its orientation, obviously). Haven't tested this in DCS, though. Of note, the yellow bars on the attitude indicator are NOT the localizer and glideslope indicators! They are "flight director" bars, which give roll and pitch instructions to get back on the localizer and glideslope. The glideslope indicator is the small arrow on the left edge of the attitude indicator, and the localizer indicator is the Course Deviation Indicator (the white needle) on the HSI. The difference between the traditional "needles" and the flight director is subtle, but significant. With the flight director Bank until the vertical bar is centered Add or decrease power until the horizontal bar is centered Scan the localizer and glideslope needles to ensure this is keeping you on (or correcting you towards) the proper approach Edited March 1, 2021 by jaylw314 1
