or do the IFR written exam questions really have much to do with real IFR flying?
I am going to go out on a limb and say YES..the IFR system is more than just flying in clouds, its as much about knowing what things like MEA,MOCA,MCA,DME,ADF,RCO,ETE,ADM,CRM,ARTCC,OROCA,ADIZ,TCAN,VORTAC,ASOS,AWOS,HIWAS are and how and when to use them. The sections on instruments couldn't be more connected to actual IFR flying (crosscheck, interpret, control) and you should be able to answer those without even having to stop and think.
Trying not to lecture here but when I took my Written Exam a few months ago after spending 6-8 months studying I thought the same thing. But when it came time to take the exam (after consistently getting +90% on the sportys exams) I noticed that all the pieces were coming together about the IFR system. It was actually an eye opener and still is.
So now I can go back and answer the questions not because of memory, but because I know the concepts behind them (most of the time). This may save your butt when it comes to digesting things like the weather charts or how to read winds aloft charts. Sure you can memorize the answers, but why? When you are flying and planning you wont see boxes with ABCD choices on the windshield, you will have to know how to process and apply it, to answer your OWN question.
Believe me, I know its ALOT of information to digest, but when you walk into the exam room knowing why things are the way they are there will be no worries of not passing. The biggest reason for the exam is to test your general knowledge of all the subjects the FAA feels are needed to fly safety in the IFR system.
Also now when I get in planes with an ADF or DME I know what it is and how it is used in the system instead of saying "whats that thing for" or "I will never own a plane with that in it so why do I need to learn about it".
