How do you confirm OFP number if no ACARS?

• A. Both pilots listen to clearance and confirm route
• B. Dispatch confirms by radio
• C. Ground crew updates the log
• D. The captain signs it

Answer: (A)

Without ACARS, the crew must rely on voice communication to verify flight details. The safest way to confirm the OFP number is for both pilots to listen to the ATC clearance and cross-check the route together. This shared audible confirmation ensures that the same OFP and route are understood by the entire cockpit, reducing the chance of misalignment between the planned flight plan and what ATC has cleared.

Dispatch confirming by radio isn’t as effective in this moment because it doesn’t guarantee both pilots heard and agreed on the exact clearance in real time. Ground crew updating the log happens on the ground and isn’t a cockpit verification method during flight. The captain signing it doesn’t provide the live confirmation of the in-flight clearance or OFP routing.
