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

Question: 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.
