SU-25 Nav Mode--how do you know?

[BBQ]

Without a hud--how do you know which Nav mode you are in while fying the Su-25?

 

Thanks for any replies!

1) reset it to another mode(ground or air-to-air) and then go back to Navigation mode. It should be at WP 1

2) Keep hitting the ~TILDE and watch the HSI waypoint information as it cycles through all the waypoints.

so then I can hit the mode change again to go to RTN mode, and hit it again for LNDG mode? I know that in enroute mode--when you reach the end, it automatically switches to RTN for the finals, and then to LND after that--just wondering if there is a cue somewhere telling me when I'm about to land!

If you hit the 1 key repeatedly you'll see the HSI has four modes. They are in order:

 

1: En route mode (defaults to waypoint 1, unless you're right on top of it).

2: Return mode.

3: Landing mode.

4: Blank (call it what you will).

...then it repeats

 

If you watch the HSI while you hit the 1 key you'll notice one of the modes does not move the course and heading needles at all, that's mode 4, you can use it as a reference for which mode you wish to be in. You can also tell you're in landing mode because it queues up the ILS needles. There is no other indication of what NAV mode you are in in the vanilla Su-25.

 

The best way to know when you're about to land is to not fly your waypoints blindly. Try to know where you are on the map, where you're heading, and where your airfield is. You can do this mentally by studying the map and paying attention to your course and bearing and it will greatly improve your overall situational awareness, or you can do it the easy way and enable the map view and your little white dynamic aircraft icon.

 

Just be careful not to hit the ~ key while you are in landing or return mode because it will switch to another airfield. Unless you know and can keep track of how may airfields there are in the game, the only way to get back to the appropriate one is to call "Inbound" when in sight of it.

(Remainder snipped)

 

Just to add: The #4 mode you mention is called "Pilot" or "Pilotage" mode. No nav data is displayed. When set to this you are navigating by landmarks. The easiest way to tell when you are in Pilot mode is to look at the ADI just above the HSI. Two red flags appear. They indicate that both the pitch and bank steering indicators are unreliable. In all other modes, these two windows are clear.

 

Concerning the Landing mode: There are two white flags (dots) on the HSI, one to the left and one to the right. These are, respectively, your localizer and glideslope deviation reliability indicators. When you pick up the localizer and and glideslope beams in Landing (ILS) mode, these flags disappear. So you will know that you are more or less in the right place and your readings are reliable.

 

It is also possible to have only one flag disappear. For instance, if only the localizer window is clear, you'll know that you have captured the localizer beam and can get accurate directions right-left steering but are still either too high or too low to intercept the glideslope.

Thanks for all the tips!

 

Ironhand--look forward to any upcoming training missions for 1.1 :) (apart from excellent a-10 voiceovers already present)
