What action should be taken when communication fails before a Time Effective Form D is addressed?

• A. Proceed immediately under the last clearance
• B. Request dispatcher to issue a new Form D
• C. Proceed only with a new Time Effective Form D
• D. Must not proceed nor be given permission to proceed until communication has been reestablished

Answer: (D)

When you don’t have confirmed authority, movement isn’t allowed. If communication fails before a Time Effective Form D has been issued, you must not proceed and you must wait until contact is reestablished and proper authority is confirmed. This prevents acting on outdated or unknown instructions and avoids potentially unsafe movements.

Reaching out to restore communication is essential. A prior clearance or the promise of a new Form D isn’t enough to authorize movement without verified contact, so the safe course is to hold and await reestablished communication before any proceed signal or form becomes effective.
