Answers so you can check yourself: 1900Z: Alternate required 2058Z: Alternate required 0930Z: Alternate required 1402Z: Alternate required 1501Z: No alternate required Check out my other videos especially the ones about how instruments and navigational aids work. I also have help videos for passing the instrument pilot knowledge exam Visit my website at www.theaviationvault.com to learn much more about aircraft dispatchers, airlines, and dispatch history!
