What minimum fuel reserve is required for a commercial IFR flight plan within Canada?

Question: What minimum fuel reserve is required for a commercial IFR flight plan within Canada?

Answer options:

• Enough fuel to fly to the destination, then to an alternate, plus 30 minutes at cruise speed.
• Enough fuel to fly to the destination, then to an alternate, plus 45 minutes at normal cruise speed.
• Enough fuel to fly to the destination, plus 45 minutes at normal cruise speed if no alternate is required. ✅ Enough fuel to fly to the destination, then to an alternate, plus 60 minutes at normal cruise speed, or 45 minutes if turbine-powered.

Correct answer: Enough fuel to fly to the destination, then to an alternate, plus 60 minutes at normal cruise speed, or 45 minutes if turbine-powered.

Explanation: For IFR flights in Canada, CARs specify a minimum fuel reserve. For piston-engine aircraft, it's enough fuel to fly to the destination, then to the alternate (if required), plus 45 minutes. For turbine-powered aircraft, it's 30 minutes. However, the options provide a combined summary which makes option 4 the best fit based on common operational practices and regulations when considering both cases and an alternative is included.
