Which acronym stands for 'minimum crossing altitude'?

• A. MDA
• B. MEA
• C. MCA
• D. MOCA

Answer: (C)

The concept being tested is how altitude constraints on instrument procedures are named. Minimum crossing altitude is the altitude you must be at when you pass a specified fix on a procedure, ensuring obstacle clearance right at that point as you move from one segment to the next. Among the options, the acronym that stands for this is MCA. The other terms refer to different altitude concepts: minimum descent altitude is the lowest altitude for descent on a non-precision approach; minimum en route altitude and minimum obstacle clearance altitude relate to enroute segments and provide obstacle clearance along routes, not the crossing point. So MCA is the one that represents minimum crossing altitude.
