The weather cancelled my plans to fly a cross-country to Iowa City and Peoria this afternoon. Instead I had a simulator lesson that introduced partial panel approaches (which involves failing two of the main instruments). I have never felt so defeated by a machine. I don’t know if it was the simulator, or me, or both, but I couldn’t hold altidues or headings at all. I didn’t think partial panel flying was going to be so hard. I understand it but I just can’t do it in the simulator. I gave up after 45 minutes and decided I’ll come back to this next time. I vented my frustration by throwing snowballs, and my instructor and I had a good laugh.
