The Performance Single Engine Piston class (Bonanzas, Mooneys et al.) is now working as it should. You can take the checkride at any flight club. It is a significant step up from the SEP checkride, so if you're not used to the Bonanza, it's recommended to take it out for a few free flights beforehand.
There's also a little trick if you want to repeat your attempt without repaying the checkride fee: given the airplane lands with engine out (it's part of the checkride), your flight auto-completes as soon as you stop the aircraft. You can however still restart a failed (or passed) checkride by stepping back on the flight completion screen in the Pilot Hub and clicking on Abandon.
This is not considered cheating. There'll be a higher difficulty career setting, which will close this loophole, but on the current, standard difficulty, you're allowed to do this.
The economy model was revised for a cca. +70-110% payout rate (depending on aircraft) compared to SEP, and a massive aircraft rebalancing was done too. Given that the Bonanza is standard aircraft for MSFS and there's a great free option in X-Plane, the global PSEP fleet is now Bonanza-heavy, but you'll find plenty of Mooneys, Arrows and SR22s across the world, plus a few hundred of each MSFS 2024 PSEP aircraft.
Enjoy PSEP, and if you face any issues, let me know on Discord!
