In the Alternate profile I plan, what are the two endpoints called?

• A. IAF to IAF
• B. IAF to FAF
• C. FAF to FAF
• D. IFR to IFR

Answer: (A)

The key idea is how an alternate planning profile is defined. In instrument flight planning, an alternate profile is drawn from one fix that starts the approach path to another fix that continues it, using fixes that mark entry points into the approach. Those entry points are the initial approach fixes. So the two endpoints you use for an alternate profile are IAF to IAF. FAFs define the start of the final approach segment, which isn’t what you’re configuring when you’re outlining an alternate entry path, and IFR to IFR isn’t a specific pair of fixes.
