In your Cougar profile use this statement:
USE MTYPE A5
In Aces High click on SETUP on the clipboard then JOYSTICK then SELECT JOYSTICK and select your mouse axis for view pitch and view yaw (see attached image). Then when you press F8 you get pan mode on the Cougar's mousestick. Some players calibrate their mousestick in Aces High but I have not and it works just fine. Of course if you want to make use of the T1 button then program something like this:
Rem
Rem Pressing button 1 enables the pan view and holds down the right mouse button to enable the view to be panned
Rem with the mousestick on the throttle. Pressing button T1 again releases the right mouse button and returns the
Rem view to the default snap view system.
Rem
BTN T1 /T /P View_Mode_Pan /R KD (MOUSE_RB)
/T /P Default_View /R KU (MOUSE_RB)
When you use this code pressing button T1 will switch you between snap mode and pan mode. Aces High requires the pressing and holding down of the right mouse button to pan with the mouse so I programmed my T1 so that I press it once to engage mouseview and it simulates the holding down of the right mouse button until I press T1 again which releases the right mouse button and engages snap view mode. This is done using the KU (Key Up) and KD (Key Down) commands.
