Definition
In the context of a Minimum Equipment List (MEL), operations procedures are the specific actions a flight crew must take to safely conduct a flight when a piece of equipment is inoperative. They describe what the crew must do — or avoid doing — to compensate for the missing or non-functioning item before and during the flight.
Plain English
If something on the airplane is broken but the flight is still allowed under the MEL, operations procedures are the extra steps the pilot must follow to fly safely without it. For example, avoiding flight at night, limiting altitude, or briefing passengers in a particular way.
Context Anchor
Seen in Minimum Equipment List entries, often when a pilot is deciding whether a flight can be made with a piece of equipment not working.
Derivation
“Operation” comes from words meaning work or action, and “procedure” means a set way of proceeding. Together, the phrase points to required actions for operating the airplane, not just a general description of how flying is normally done.
Why Pilots Care
Ensures the flight remains legal and within safe operating limits when equipment listed in the MEL is inoperative.
Intuition Check
Do not read operations procedures as ordinary company habits or a casual way of doing things. In the MEL context, they are required steps tied to a specific item that is not working.
Example Sentence 1
The MEL allowed the aircraft to depart with one landing light inoperative, provided the operations procedures restricting the flight to daytime were followed.
Example Sentence 2
The MEL listed operations procedures that had to be completed before dispatch with the fuel quantity indicator deferred.
