FAA Instrument Rating Airplane (IRA)Regulations and CurrencyMedium

An airport a pilot wants to use as an alternate has only a published nonprecision approach procedure — no precision approach is available. No special alternate minimums are listed on the chart. What are the standard alternate minimums that apply for filing this airport as an alternate?

  1. A600-foot ceiling and 2 statute miles visibility
  2. B800-foot ceiling and 2 statute miles visibility
  3. C400-foot ceiling and 1 statute mile visibility
  4. D1,000-foot ceiling and 1 statute mile visibility
Show answer & explanation

Correct answer: B. 800-foot ceiling and 2 statute miles visibility

Standard alternate minimums are 600-2 for airports with a precision approach and 800-2 for airports with only a nonprecision approach. Since this airport has only a nonprecision approach, 800-2 applies.

Why the other options are wrong

  • A. Incorrect — 600-2 applies only when a precision approach is published.
  • C. Incorrect — far below standard alternate minimums.
  • D. Incorrect — not a standard alternate minimum value.

Standard Alternate Minimums

Default alternate weather minimums are 600-2 for airports with a precision approach and 800-2 for airports with only a nonprecision approach, unless the chart specifies otherwise.

  • 600-2 = precision approach available
  • 800-2 = nonprecision approach only
  • Charted 'NA' or specific alternate minima override the standard

Memory trick: 6 for precision, 8 for none — remember 600/800 by the approach type.
