Hippo Posted December 28, 2008 Posted December 28, 2008 Regarding the desired track / heading, and radar / barometric switches for the autopilot. The manual seems to suggest that these are two-position switches, whereas they are 3-position in the sim. I was trying to get the autopilot to follow a track and the only way I could get this to work was by using the "middle" (unlabelled) position of the switch? Am I missing something here; does anyone have a better explanation of what's going on with these switches?

EvilBivol-1 Posted December 28, 2008 Posted December 28, 2008 Just tested to be sure. In the middle position, the AP will fly the last-trimmed heading. - EB [sIGPIC][/sIGPIC] Nothing is easy. Everything takes much longer. The Parable of Jane's A-10 Forum Rules
Kraz75 Posted January 21, 2010 Posted January 21, 2010 How about the radar / barometric switch middle position? I can't find any posts here on what it does exactly, nor in the manual. I understand what either mode does, but not this. AMD Phenom II x6 1055T 2.8GHz / GeForce GTX 460 / 8Gb Ram / Windows 7 64 bit / X52 Pro / TrackIR5
Frederf Posted January 21, 2010 Posted January 21, 2010 The DT-M-DH switch and the BR-M-RD switch can be thought of as data source selectors that "drive" the respective hold functions. The middle position of the DH-DT switch is a "no source" selection which is identical to, say, DH but without any PVI or PRT tasklights illuminated. In other words the hold just keeps the last trimmed heading. The middle position of the RD-BR switch is similar. In this case "no source" effectively means the ALT hold function has no data input and thus does nothing, the same as if the hold was off altogether.
mdee Posted January 21, 2010 Posted January 21, 2010 How about the radar / barometric switch middle position? I can't find any posts here on what it does exactly, nor in the manual. I understand what either mode does, but not this. It automatically switches between radar and baro based on altitude.
Frederf Posted January 21, 2010 Posted January 21, 2010 Yeah but it has three positions: radar, baro, and one in the middle.
Eddie Posted January 21, 2010 Posted January 21, 2010 Yeah but it has three positions: radar, baro, and one in the middle. Radar position selects the Rad Alt and only the Rad Alt, Baro position selects only the Barometric altimeter, the middle position allows the avionics to display the most relevant of the two. ie Rad Alt below 300m, baro above.
Frederf Posted January 22, 2010 Posted January 22, 2010 Lies. The middle position on the BR-RD ALT hold sourch switch isn't AUTO it's NONE. The HUD display of radar or barometric altitude data is not related.
