Whether you have extensive jet experience in a charter or corporate environment, come from a military background, or perhaps you’re a CFI headed to an airline, this course uncovers the elements specific to 121 airline flying that you may not be familiar with but definitely need to know!
Airline flying has several operational factors specific to 121 operations. Items such as Operational Control, Dispatch Releases, Amendments, and Operations Specifications (Op Specs) are just a few of the terms you will expect to hear in an airline cockpit. Content covered in this course includes:
  • Terminology

  • Alternates
  • Briefing a Jeppesen Chart

This course fills a crucial gap relating to the operating of an aircraft specifically in an airline environment. Think of an airline cockpit as a mass orchestra and you’re the conductor! Learn about each member of your orchestra, your part in the music, and how to keep tempo in your new role.

The videos simplify the 121 world well. It was not overly complicated and did not throw in unneeded information.

This course is useful not only to pilots but also to ground operations workers (Ops Agent and Ramp Agent) and to Supervisors (Above the Wing, Below the Wing, and Duty Supervisors at smaller stations)

Course Completion Review
Outstanding video product, although for a course that is completed in less than one hour, it is possibly at a somewhat high price point for the intended audience.  

I'm already a Part 121 pilot but found this to be a great review of the subjects I had to learn the hard way and/or never quite really understood well.  I see room for expansion to add other topics of interest to prospective airline pilots to this course, like what to expect in a typical AQP training footprint, how to employ CRM to abnormal/emergency procedures, etc.
