Hello Anotherwanabee,
Thank you for your information on the SIM session. I will do the SIM on the Seneca in few days in HAM. I really imagine that this is very basic flying (turns, climbs, descents, ILS, holdings, G/A...) and it seems the examiner is relax so I'm not so worried.
Can you please just tell us what the SIM looks like: do you have to know procedures (i don't know the seneca) and all the configurations (RPM and mixture for example)? Have you had any experience on this A/C? You confirm the charts provided are Jeppesen and not LIDO as on the A320 SIM? Did you choose the airport where you operated?
Regarding the 2-month period before you can attend the CQ, don't be afraid, i passed the DLR in 2017, and 9 months after I was invited to continue the process with the SIM.. I just that they cannot hire 200 pilots in 2 months, rather it is diluted on several months/years, that's why they don't need you immediately.
Good luck !
