Intro

Most of the oral was one long IFR cross-country, and the flight didn’t go as briefed.

• This is a review of my Instrument Rating checkride: the questions the DPE asked and how the flight actually went.
• Most of the oral was built around an IFR cross-country scenario. The DPE opened my ForeFlight briefing and went through it item by item, from NOTAMs to approach charts.
• For a keyword review of the oral topics, see my Instrument Rating Checkride Oral Cheat Sheet. For my PPL checkride, see My Private Pilot Checkride: Oral and Flight Review.

Intro

• There’s a lot to study for your IR checkride oral, and trying to review everything can be inefficient when you’re short on time.
• So, I’ve summarized and simplified the essential knowledge into a very simple format.
• This isn’t a detailed, in-depth explanation of each topic.
• It’s meant for quick review when you want to rapidly go over everything you’ve studied, especially in the week leading up to your exam.
• For what the DPE actually asked on my checkride, see My Instrument Rating Checkride: Oral and Flight Review.
