Do you fly in RVSM airspace? Or do you manage aircraft that fly in RVSM airspace? Do you fly air tours under § 91.147?
If your answer to any of the above-questions is “yes”, then you should be familiar with letters of authorization (“LOAs”). But do you understand who actually needs to apply for and be issued an LOA?
