Others on another thread have shared binding 'Take control of character" and using that to enter a non-24 airplane. This works with a few FF/LL like the MU-2, V35B, and T207. And it should work with any 3rd party add ons that are 24 compatible but not 24 feature ready, i.e., walk arounds. Now I can start cold and dark, hit a key, get in and start up as in 2020. Thanks to anyone who called out this binding above or elsewhere, a real find if one flies such aircraft!
