The Relationship Between MEL, DDG, and CDL in Airline Operations Part 1

Описание: The Master Minimum Equipment List (MEL), Dispatch Deviation Guide (DDG), and Configuration Deviation List (CDL) are three critical tools that determine whether an aircraft is legally and safely dispatched when something isn’t working or installed.

In this video, we break down how MEL, DDG, and CDL work together in real airline operations, explaining:

What each document is responsible for

How the DDG supports MEL performance penalties

When the CDL applies to missing or damaged aircraft components

How maintenance, dispatch, and flight crews use these tools collaboratively

Common misconceptions and real-world dispatch decision examples

Whether you’re maintenance, flight crew, dispatch, or a student in a GenFam course, this video clarifies how dispatch deviations are evaluated and why an aircraft can still operate safely—even with deferred items.

If you’ve ever asked “Can we legally go?”, this video explains exactly how that decision is made.
