Final answer:
The FAA gives an airman a chance for an informal conference before proceeding with certificate revocation, allowing them to present their case and potentially resolve the issue without further legal actions.
Step-by-step explanation:
When the Federal Aviation Administration (FAA) seeks to revoke an airman certificate, due process is observed by providing the certificate holder an opportunity for an informal conference. This procedure allows the airman in question to discuss and dispute any allegations or findings before any formal action is taken. The purpose of the informal conference is to ensure that airmen have a chance to be heard and to present any relevant evidence or information that might influence the FAA's decision. It also offers a possibility for the issue to be resolved without the need for further legal proceedings.
