Definition
Aircraft-specific written procedures completed during the cruise phase and prior to and during descent, used to configure the aircraft, verify systems, and prepare crew and passengers for the transition from level flight to approach and landing.
Plain English
Step-by-step lists the pilot works through while at cruising altitude and on the way down, making sure the aircraft and crew are ready for the descent and the approach that follows.
Context Anchor
Seen in instrument flight and high-performance aircraft procedures, especially before leaving cruise altitude and while preparing for the arrival.
Why Pilots Care
Following them reduces the risk of configuration errors or missed steps during phases of flight with increasing workload.
Intuition Check
Do not read “cruise” here as relaxing or sightseeing; it means the normal level part of flight between climb and descent. Do not read “descent” as simply pointing the nose down; it means a planned, controlled move to a lower altitude.
Example Sentence 1
After leveling off at FL350, the captain called for the cruise checklist and confirmed pressurization, fuel balance, and engine parameters were normal.
Example Sentence 2
High-performance aircraft demand careful attention to cruise and descent checklists to manage speed and altitude precisely.
