Scenario 2: Under what condition is an alternate aerodrome NOT required for a planned IFR flight?

Question: Scenario 2: Under what condition is an alternate aerodrome NOT required for a planned IFR flight?

Answer options:

• If the destination has an operational control tower. ✅ If the destination weather forecast (TAF) for one hour before to one hour after ETA indicates a ceiling of at least 1,000 feet above the lowest approach minimums and visibility of 3 statute miles or 1 statute mile above the lowest approach minimums, whichever is greater.
• If the destination is equipped with a serviceable ILS system.
• If the pilot has accumulated more than 100 hours of IFR flight time.

Correct answer: If the destination weather forecast (TAF) for one hour before to one hour after ETA indicates a ceiling of at least 1,000 feet above the lowest approach minimums and visibility of 3 statute miles or 1 statute mile above the lowest approach minimums, whichever is greater.

Explanation: An alternate aerodrome is not required if the destination weather for +/- 1 hour of ETA meets or exceeds specific minimums: 1,000 feet ceiling above approach minimums and 3 SM or 1 SM above approach minimums visibility. This reflects the confidence in weather prediction for that period. The correct answer is "If the destination weather forecast (TAF) for one hour before to one hour after ETA indicates a ceiling of at least 1,000 feet above the lowest approach minimums and visibility of 3 statute miles or 1 statute mile above the lowest approach minimums, whichever is greater.". This capacity-fill scenario 2 reinforces the same competency for the inrat bank and follows the certified explanation standard.
