Heh ;) I don't mind top or bottom replies but sticking them in
the middle throws me a bit.
Anyway... I can't find any problems here - cvs a day or two old
- I tried just calling fgfs with no params, to get the C-172,
and could scroll backwards and forwards through the views ok.
Cycled forward to chase w/o yaw, cycled backwards from it - no
problems.
Then tried both the A-10s, because you mention that they had no
chase view w/o view and had no problems there either, including
the chase view w/o yaw.
Do you get a 'Drop View' with the A-10s? The Drop view should be
the 'last' view on the A-10s, before you end up back in the
Cockpit and should come after the chase view w/o yaw. Do you
get both the chase view w/o yaw and drop view on the A-10s?

Lee, thank you for your interest and suggestions...
Sorry, I tend to put the answer right by the question, less chance of
forgetting to answer something... 8-(
There is NO chase view on my A10s -- cockpit view, helicopter view,
chase view above, chase view, tower view, tower view look from, drop
view and then back to cockpit view -- NO chase view w/o yaw. I am
using latest cvs.
Calling flightgear with no --aircraft param, I see the problem: the
views are --
cockpit view, helicopter view, chase view above, chase view, tower
view, tower view look from, chase view wo yaw, THEN helicopter view
(again, note NOT cockpit view), but if I reverse from the 2nd
helicopter view, I DO get cockpit view as I would have expected, then
backing up again, the screen is labled chase view wo yaw, but is
really just cockpit view. Except for the first time, there is NO
cockpit view moving forward with 'v', moving backward, I see cockpit
view where it belongs, but 'V' stops working with a screen labelled
chase view wo yaw, but that looks like cockpit view.
Using --aircraft=Citation-II, I get the following views:
cockpit view, helicopter view, chase view above, chase view, tower
view, tower view look from, chase view wo yaw, THEN helicopter view
(again, note NOT cockpit view), but if I reverse from the 2nd
helicopter view, I DO get cockpit view as I would have expected, then
backing up again, the screen is labled chase view wo yaw, but is
really just cockpit view. Except for the first time, there is NO
cockpit view moving forward with 'v', moving backward, I see cockpit
view where it belongs, but 'V' stops working with a screen labelled
chase view wo yaw, but that looks like cockpit view.
In other words, going forward with 'v', the views are:
CV, HV, CVA, CV, TV, TVLF, CVWOY, HV, CVA, CV, TV, TVLF, CVWOY, HV,
CVA, CV, etc.
going back with 'V' on a broken aircraft here, I'd get:
CVA, HV, CVWOY (stuck at this point and 'V' doesn't work anymore
until I move forward with 'v' first)
The a-10s don't have CVWOY, cycling backwards or forwards, I get:
CV, HV, CVA, CV, TV, TVLF, DV, CV, HV, CVA, CV, TV, TVLF, DV, CV, HV,
CVA, CV, etc.
So, the broken aircraft have chase view wo yaw instead of drop view
and don't display the 2nd or more cockpit views going forward (after
CVWOY and before helicopter view) with 'v', but will display cockpit
view with 'V' (backwards), but 'V' stops working when you get to the
CVWAY view, until you move forward with 'v' again first.
I'm now even more confused than when I started! 8-)
Hope this helps,
Thanks! Ima
