When loading a mission you are not quite certain what the current setting of the aircraft are like flap settings, throttle, mixture etc. This is particuarly true for the landing missions where you load in and they intend to have you configured for landing but if the levers on the throttle quadrant are set different for throttle and flaps you might load in at full throttle with no flaps and have to figure out what setting they need to be in.
The request is before loading into a mission to be given a summary of the current aircraft configuration including flap setting, throttle, mixture, trim, switch settings like avionics bus etc. What would be REALLY nice is if it detected your current inputs and would alert you and hold off loading for example before it loads it stopped and said “Mission starting throttle is 60%, Controller Z axis set to 90%” and then let you set everything to match the preconfigured settings.
