    A 91.155 puzzle

    Here is an interesting analysis that came up in my college 141 class. 91.155d requires 3 miles ground (or 3 miles flight viz in lieu of) viz to takeoff land or enter the pattern(only) at an airport for which the surface area is designated. (What is conspicuously absent is flight through the...

    Ah, the mag vs true wind raises its ugly head again

    “ If you read it it’s true, if you hear it it’s magnetic”. Remember that? Add the different sources to the mix and no wonder students get mixed up. ASOS is usually configured to true. The ASOS usually gets transmitted to the system directly and the METAR (you read a METAR) reflects the true...

    Takeoff minimums, are you sure?

    we know that standard TO mims are 1 or 1/2 vis with expected climb gradient of 200 fpnm and a diverse turn no lower than 400 agl. Let’s take another example. Fort Worth Borland. STD/w min climb of 512’ per NM to 1300. Question: what happens at 1300? Careful how you answer. Look at the...

    61.57c approaches

    This is a simple question.... Must the approaches used to comply with 61.57c IFR currency be in actual or simulated IFR conditions....or...may they be done in VMC conditions? I’m interested in what you guys think and why you think that. In other words, whatever you think, what is your...

    I have several questions relating to a research project for a class I'm teaching in college. They are all directly or indirectly related to IFR departures. I will probably asks these if two or three different posts. My goal is to clarify as precisely as possible the distinction between...

    Is a medical necessary for this?

    A prospective student asked end me an interesting question... Must he have a medical for me to give him a flight review or an IPC? My thought is that I would be PIC in the IPC anyway so that doesn't require him to have one, and I would simply act as PIC for the review as well so, again, he...
