A few years ago I tried to write a sim scenario to end up flapless and slatless and couldn't come up with something sensible...
I don't know, the kids these days....
Slatless ferry, then flap asymmetry. I found the approach quite interesting, getting the speed stabilised was quite hard as it was quite easy to overcontrol the thrust needed.
But for real fun, try a total hydraulic failure in the sim. No speedbrakes, no flaps, no slats, no TPI, free-fall the landing gear, no nosewheel steering and only accumulator brakes. That's why they recommend the longest runway you can find - you've probably only got London Airport or Frankfurt to choose from!
I found the TPI wasn't as much of an issue with a total hydraulic failure in the K3 sim as I thought it would be - there wasn't much out of trim force at the recommended approach speed if the TPI had frozen at the cruise setting.
