I lke screen recorder very much especially the tower views.
However the sound of the approaching or departing plane is tempered (apparantly that is to simulate the noise tempering glass in the tower)
But I also use the tower views as a spotter's view (looking up the gps coordinates in google earth and "create" a "tower", 5ft AGL the height of my eyes when I stand up straight ), 1x zoom).
Of course it would be nicer to hear the full sound level (as in spot view), of course increasing or decreasing when it approaches or gets farther away
Then a lookaround view wouldn't be bad either, you can move the tower view angle, but it keeps aimed at your plane.
Now for VATSIM and IVAO Newbies (like me, who are just parked to observe, listen and learn) it would be nice to have a look-around view in tower mode.
This shouldn't be to difficult I think, since this only needs to be a 360 degree circle and the possibility to adjust your viewpoint vertically (in degrees, not linear)
About the tower sound level, isn't there a possibilty in fs9.cfg, so I can tweak the volume?
