Here you go OBIO, best way I know if you do not have Active Camera is the Fly-By Module. Drop the .dll module and .ini configuration file in the FS9 > Modules folder. After you have chosen a flight and loaded it, click Alt and go to Add-ons and scroll to the Fly-BY Module and activate it, then scroll it again and set up the configuration. The Fly-By module will work any time you go to the Tower View.
