Definition
A regulatory and operational expression covering every segment of a flight from preflight planning through engine shutdown, including taxi, takeoff, climb, cruise, descent, approach, landing, and post-landing rollout. When a rule, procedure, or piece of equipment is described as applying to all phases of flight, it applies continuously across every one of these segments without exception.
Plain English
Every part of a flight, from getting ready on the ground to shutting down at the gate. If something is required for all phases of flight, it has to be in place the whole time, not just in the air.
Context Anchor
Seen in electronic flight bag guidance when describing whether a device, mount, display, or procedure may be used throughout the flight operation.
Why Pilots Care
Regulatory and equipment requirements often apply across the full flight rather than isolated segments, affecting what tools and procedures may be used.
Intuition Check
Do not read “flight” here as only the cruise portion or only the time airborne. In this phrase, it covers the full operation from ground movement before takeoff through ground movement after landing.
Example Sentence 1
The EFB is approved for use in all phases of flight, so the pilot can reference charts during taxi as well as in cruise.
Example Sentence 2
Preflight planning must consider performance data needed for all phases of flight, not just cruise.
