Can you depart or land with a missing temperature report?

Can you depart or land with a missing temperature report?

• A. In the US you may depart or arrive with a missing temperature report if RTMA is used
• B. You may depart or arrive with a missing temperature report in any country
• C. You may not depart with a missing temperature report under any circumstances
• D. You may land with missing temperature in the US if not RTMA

Answer: (A)

Missing temperature data can stall performance calculations, since temperature affects density altitude and engine/aircraft performance. In the United States, there is a specific exception: if Real-Time Mesoscale Analysis (RTMA) data is being used, you may depart or arrive with a missing temperature report because RTMA provides the temperature information needed for those calculations. This is a country-specific allowance—outside the US, a missing temperature report isn’t permitted. So the correct understanding is that you may depart or land with a missing temperature report in the US if RTMA is used, rather than universally or under other conditions.
