The nit is with one of the parts of the answer to Question 11. As the answer to question 3 says, our minimum descent altitude for this approach is 1100 feet, but thats MSL. (Basic minimum for the LOC-7 approach is 1000 MSL, to which we added the required 100 feet for remote altimeter.) As the chart says, that 1000 MSL translates into 611 feet above the touchdown zone elevation of 389 feet, so 1100 MSL is 711 feet above TDZE (and 703 feet above airport elevation).

Key Takeaways:

The article clarifies the distinction between AGL and MSL in aviation measurements, correcting a previous quiz answer regarding weather minimums and identifying the Everglades crash aircraft as an L1011, not a DC10.
It confirms that IFR currency rules have not changed; the "six months current, followed by a six-month grace period with a safety pilot" rule remains in effect, dispelling persistent rumors.
A pilot shares a strategy for efficiently maintaining IFR currency by planning a specific round-robin flight route to practice multiple approaches in a concentrated period.

Is that AGL or MSL?

OK, I’m going to pick one tiny nit about the April 2019, Killer Quiz. Anywho … good quiz, and—oh boy, what a Charlie-Foxtrot this pilot has gotten him/herself into.
