Under MC-3, what is allowed?

• A. All operations normal
• B. You can service but not board pax
• C. No service or pax until cleared
• D. Flight cancelled

Answer: (C)

MC-3 puts the operation on hold until explicit clearance is received. The idea is safety first: when MC-3 is active, you don’t load passengers or run in-flight or gate service until the appropriate authority has reviewed the situation and granted clearance. This prevents moving forward with potential issues that could affect safety or compliance.

So, the correct approach is to stop all service and passenger movement and wait for clearance before resuming. Operating normally would skip the needed safety check, and allowing service without boarding would still expose people to an unresolved issue. Cancellation isn’t automatically required by MC-3; clearance can allow a resumption if the issue is resolved.
