Terrain Avoidance

[+SupGen 79]

Is there a Terrain Avoidance, Terrain Following, TA, TF, or whatever radar mode in Avionics70 or is it just GM (Ground Mapping)?

[+EricJ 4,245]

GM only

[+SupGen 79]

Ok, thought so, thanks.

i think only available in the avionics60.dll

 

you'd think the stock SF2NA A-6 TRAM would have it, but it's main ini dosen't even LIST an avoinics dll, let alone an avinoics .ini (the stock ones!

The tweeks/mods somebody did (don't even remember if it was me or not!), has it listed in the avionics ini. The 'ground clarence' height is easily adjusted in the avi ini

Terrain following in older aircrafts was pretty much a automated business/multi-crew task

 

I dont remember right now if the early nap-of-the earth flight machines (B-47, B-52 late models, etc) had full terrain following capacity, but in the F-111 and B-1B, terrain following is performed by the aircraft... so, to emulate some sort of terrain following (in night or adverse weather) just planning a very low altitude route and turn on the autopilot (the full one) and you can use the terrain avoidance standard mode as a "monitoring" feedbacks as happens in most cases with those machines, the last requisite is to tweak the aircraft's INI minimum AI level of flight (200 300 or 600 ft) so the autopilot will flight the machine close to the ground/sea.

 

I never tried this before, but seeing low altitude AI flights, shows that the result is a kind of "soft ride" mode in most cases, but the AI isn't smart enough and sometime it crash into very high peaks. Well, I think that for avoid this, you must monitoring all flight with the terrain avoidance scope to override the AI for that type of "malfuntion", as in the real life.

 

Is matter to experiment a little bit and do some testing to obtain a usable pseudo-TF mode.

Thanks much to everyone who answered. Seems like TERRAIN_AVOIDANCE is only availabla in Avionics60, as EricJ and Wrench said. Reason I asked is I just started fooling around with the SF1 version of the Mirage2000N, (the one by Amokfloo by way of fougamagister) I kinda like the dual cockpit thing. I converted it for SF2 and the only problem was that the radar didn't work. At all. Now I seem to remember reading somewhere, some time ago, that the problem was somehow due to the dual pit. (I searched for this topic yesterday, but couldn't find it so maybe I'm wrong about this). In any case, this wasn't the problem at all; in the main .ini the aircraft was using Avionics70, meanwhile the Avionics .ini used the Avionics60 statements; i.e. GROUND_MAP and TERRAIN_AVOIDANCE rather than GM. Once this was corrected the radar works fine. I think because all of the info I can find says the Antilope5 was strictly a terrain following radar I'm going to use the Avionics60.dll and see how that works out. Now the other thing, aside from the fact that you can move from the front cockpit to the rear one and vice versa is this, and this is in reference to another thread I think I remember , is the aircraft has a grey "GreenTVFilter" which seems to work. In that thread, I think IanH was responding to a question on that subject and the upshot was that it wouldn't work. What's in a name? Anyway, thanks for the help and Oh yeah, does anyone else think this kind of pit would be kinda cool for F-4s, F-14s, F-15Es, and other twin cockpit planes? I haven't messed with this one enough to discover any major drawbacks so if anyone has thoughts/experience on this, feel free to post.

 

Whoops: One more question; is TEWS only available in Avionics70?

yes, 70 only

[+SupGen 79]

I dunno, I seem to be getting a TEWS display in both Avionics60 and 70. The first two pics are Avionics60, the second two are Avionics70.

COOL!!

never noticed!

[+SupGen 79]

Yeah, sometimws I find stuff out because I don't know enough to "know" it won't work! So, Wrench what do you you think about the dual cockpit thing, in general?

Thats a good memory you've got there SupGen! I was after an IR look to the TV display (grey/white only) but the best we could come up with is the same as the 2000N you posted here where there is a grey filter over a colour display.

[+SupGen 79]

Ah, so I did remember something, anyway. Thanks, IanH!
