The Hawk T1 is equipped with a front and rear cockpit, and both cockpits are fully-functional and configured just like the real aircraft. The front cockpit is used for solo flight and the rear cockpit is used by a flight instructor or passenger (for example ground crew). The rear pilot can be toggled on/off using the 'Rear Pilot' option on the EFB tablet.
Cockpit camera presets allow you to quickly jump between the two cockpits. From the MSFS camera window, select Cockpit > Pilot and then select either PILOT (front cockpit) or COPILOT (rear cockpit).
The camera can also be moved between front and rear cockpits by triggering the TOGGLE TAIL HOOK control assignment.
