Regulation Fine Points

Ill admit it: I enjoy searching out some little-known gems in the regulations. Some, of course, are items we should know-but often dont. Others are almost so esoteric that it simply might not matter to most of us.

Key Takeaways:

Airspace, not IFR flight, dictates transponder and ADS-B Out requirements, with specific rules for various airspace classes and altitudes.
While 121.5 MHz ELTs are legal if previously installed, their satellite monitoring has ceased, and any replacement or new ELT must be a 406 MHz unit.
Pilots can technically dip below Decision Altitude (DA) during a missed approach on a precision approach, but cannot go below Minimum Descent Altitude (MDA) on a non-precision approach.
Complex aircraft are no longer required for certain commercial pilot and CFI checkrides, but 10 hours of complex training is still legally mandated for the commercial certificate.

I’ll admit it: I enjoy searching out some little-known gems in the regulations. Some, of course, are items we should know—but often don’t. Others are almost so esoteric that it simply might not matter to most of us.

Let’s poke around and see if we can teach you something. Better yet, perhaps we’ll uncover a misunderstanding you had. In the extreme case, we might even save you from a bust someday.
