Digital operations manuals provider AviationManuals has published its revised complimentary guide to understanding Minimum Equipment List (MEL) requirements.

“An MEL is the best and most widely accepted way to determine the conditions under which a flight can be commenced with inoperative equipment,” says CEO Mark Baier. “This complimentary MEL guide helps flight departments understand where and when an MEL is required and why they should consider getting one.”

The MEL Guide describes: differences between a Master Minimum Equipment List (MMEL) for aircraft types and a custom MEL for an operation's actual aircraft; requirements for operators based on state of registry and area of operation; and value of a Nonessential Equipment and Furnishings (NEF) programme.

AviationManuals supports a client base that operates over 4,500 aircraft worldwide, including 62 Fortune 100 company flight departments. Based in the Washington, DC area, the company provides digital operations manuals with update services, as well as SMS software and iPad apps for fixed-wing, rotary-wing, drone operators, and FBOs worldwide.
