It’s a GROL that’s all you need to know. There is no special GROL for AIRMEN, or Mariners, or radio Technicians, they are all the same!

How to Obtain a License

Submit FCC Form 605 along with the appropriate Proof of Passing Certificates (for the requisite written examination elements). Use the FCC Form 605 and the FCC Form 159 (fee processing form) to replace a lost, stolen, or mutilated license.
