erjdriver Posted June 25, 2015 Posted June 25, 2015 I'm playing around with flight director mode. I read the manual - there are some visual examples - it says the indicators are commanding pitch up and down. I don't see what to look for the pitch command. I see the bank and altitude commands - but not pitch. Or is that inferred from the speed gain/loss.
Maulkin Posted June 25, 2015 Posted June 25, 2015 The indicators on the HUD are giving both pitch and bank information. --Maulkin Windows 10 64-bit - AMD Ryzen 9 5900X @ 3.7 GHz - 32 GB DDR4 3600MHz RAM - EVGA FTW3 RTX 3080 - Asus Crosshair VIII Hero motherboard - Samsung EVO Pro 1 TB SSD - TrackIR 4 Pro - Thrustmaster Warthog - Saitek rudder pedals - Lilliput UM-80/C with TM Cougars
erjdriver Posted June 25, 2015 Author Posted June 25, 2015 The indicators on the HUD are giving both pitch and bank information. Yes I read that. But what am I looking for - the pitch indicator. The only thing I can think of is drawing a virtual line between the 2 parallel altitude indicators and if the 0 pitch dot is above it - i need to pitch down and vice versa.
King_Hrothgar Posted June 25, 2015 Posted June 25, 2015 I think you may be thinking it's something it isn't, though I'm not sure what. What flight director does is put any activated autopilot channels into a stabilization mode. This allows for semi-manual control without the aircraft drifting all over the place constantly. Think of it as a fly by wire system, similar to what the Su-27 has in DCS. Alternatively, you could think of it as traction control on your car. It is worth pointing out that FD doesn't do anything if other AP channels are not turned on. If you have only pitch turned on with FD, then it will stabilize your pitch only. The same applies to the other channels. Generally speaking, FD is used with pitch, bank and heading channels, but not altitude. Just like traction control on a car, this will reduce maneuverability some. Separately, the HUD features a pitch ladder just like any other aircraft with a HUD that is completely independent of the AP systems. If FD is switched on, it places a bracket like thing on it and makes it centered and horizontal (relative to the HUD, not ground) whenever you trim the aircraft. This icon on the HUD is intended to tell you how the aircraft was angled when you trimmed it, nothing more. I find it of no value and ignore it entirely. This bracket appears even if FD is not operating on any AP channels.

What I'm saying is that the roll indicator is also the pitch indicator. If you place the attitude bar between the bars of the FD indicator you will have both the roll and the pitch. --Maulkin Windows 10 64-bit - AMD Ryzen 9 5900X @ 3.7 GHz - 32 GB DDR4 3600MHz RAM - EVGA FTW3 RTX 3080 - Asus Crosshair VIII Hero motherboard - Samsung EVO Pro 1 TB SSD - TrackIR 4 Pro - Thrustmaster Warthog - Saitek rudder pedals - Lilliput UM-80/C with TM Cougars
erjdriver Posted June 25, 2015 Author Posted June 25, 2015 Ok I think I was thinking that... I need to align the aircraft icon (datum) with the 2 altitude/attitude bars - both pitch (pitch axis) and bank (roll axis) So the diagram below indicates i'm flying correctly right? = -----\/------ = Whereas below means I need to pitch up. = = -----\/------
King_Hrothgar Posted June 26, 2015 Posted June 26, 2015 Correct and I understand what you are trying to do with it now. In general, all you have to do in this particular sub mode is keep the inner bar lined up with the outer bars to follow the assigned route.
