What is the final decision point for determining if you have the required weather for takeoff on an IFR flight plan?

• A. When you receive your IFR takeoff Clearance
• B. ATC weather briefing
• C. When you depart IFR from VFR weather
• D. When you reach the destination airport

Answer: (A)

In IFR operations, the weather you need to meet for takeoff is tied to the moment you’re cleared to depart. The final decision point is when ATC issues your IFR takeoff clearance. That clearance is the authorization to begin the departure under IFR, and the weather minima for that airport/runway must be met at the time you receive it. If the weather isn’t at or above those minimums, ATC won’t give the clearance, and you’d either wait for conditions to improve or cancel IFR and depart under VFR if possible. The other steps—checking weather briefing, departing from VFR, or reaching the destination—don’t establish the moment you’re legally able to take off under IFR.
