It seems all tower views are the same height.
Apparently true, being some arbitrary height above a reference elevation or height. Even at (default) airports that have a 'tower viewpoint' defined, as their heights are most often set at 0.0m agl.
Is there a way to raise the tower views so they are more realistic?
As mentioned, you could edit the 'tower viewpoint' definition for each airport, using the Afcad like programs, ADE or Flight1's AFX.......or:
Try an edit I 'stumbled onto' in the 'Cameras.cfg' file to allow moving the towers 'eyepoint'.
The 'working' Cameras.cfg file is in the same folder as your fsx.cfg file (in XP....\Documents and Settings\
\Application Data\Microsoft\FSX\....). Note:
