The ones in the plane. Fuel system, electrical, etc.


the dpe can ask about any system he wants you just have to prepare for them all. IIRC on my oral we discussed pitot static and flaps




Ones that pertained to the aircraft I was flying. We were asked about G1000 stuff with pitot static and gyros, electrical we were just asked what’s on a certain bus and voltages of battery/alternator. Just have a good general understanding of how they work! And read the ACS!


Easy… https://www.youtube.com/watch?v=VcZe8\_RZO8c


wow I didn't get asked about the flux capacitor until CPL


This isn’t a sarcastic answer I promise. Check out the ACS (Preflight Preparation-> operation of systems)! It’s one of the most under utilized resources when studying for check IMO. It’s insane the number of students that came to me without ever cracking it open. If you can reasonably explain how all of those work you’ll be fine. If you’re asking what we personally got asked I’m pretty sure mine was fuel/oil/hydraulic, engine, flight controls (tied in with some aerodynamics), and environmentals. But that was a long time ago.


Thank you for your advice, I'm taking a look at the acs now!


Ask people who have used the same DPE what systems they discussed. You'll need to know them all, but maybe you spend more time on the ones that are often brought up.


I transitioned glider to ASEL, so my DPE did touch a bit on engine systems, but not a ton. However, does not really matter my experience or anyone elses.....Just know all the systems in the aircraft you'll be using, because that's what he can ask you.


More or less all of them. The first system question I ever got during a checkride was for my sport ticket and it was something like 'for every fluid in the airplane, tell me what it is, where it is, what it does and how to know if you've got enough'.


Big ones are engine, electrical and fuel, but you might also get instruments depending on your airplane/DPE


Asked engine questions, asked about the fuel system (c-152), and pitot-static questions.
