Definition
The phase of flight that occurs after cruise but before the aircraft begins its descent toward the destination airport, during which the pilot prepares for arrival by reviewing weather, briefing the approach, setting up navigation and communication equipment, and planning the descent profile.
Plain English
The period right before you start coming down from cruise altitude, when you get everything ready for the arrival and landing.
Context Anchor
Seen in risk-management and cockpit workflow discussions, especially when a pilot pauses before descent to review the situation and plan the next phase of flight.
Derivation
Built from the prefix 'pre-' (Latin, meaning 'before') and 'descent' (from Latin 'descendere,' to climb down). So 'predescent' literally means 'before the going down' — the time just before you start your descent.
Why Pilots Care
Allows review of aircraft configuration, weather, navigation, and personal readiness before descent begins, lowering workload and risk during a busy phase.
Intuition Check
Predescent does not mean the airplane is already descending. It means the time or check before the descent begins.
Example Sentence 1
During the predescent phase, the pilot pulled up the destination ATIS, briefed the approach, and ran the descent checklist.
Example Sentence 2
As part of the predescent checks, the approach was loaded and weather was confirmed.
