Definition
The combined settings of an airplane during cruise flight — typically flaps and landing gear retracted, engine power set for cruise, and the airplane trimmed for steady, level flight at a chosen airspeed and altitude.
Plain English
How the airplane is set up when it is flying along normally between climb and descent — clean, trimmed, and at a steady cruise power setting.
Context Anchor
Used when learning and practicing straight-and-level flight in the normal cruising part of a flight.
Derivation
Cruise comes from the Dutch kruisen, meaning 'to cross,' originally used for ships sailing back and forth across an area. In aviation it came to mean the steady, level portion of a flight. Configuration comes from the Latin configurare, 'to shape together' — referring to how the airplane's parts (flaps, gear, power) are set up.
Why Pilots Care
Each configuration has its own performance numbers — speeds, fuel burn, handling. Knowing the airplane is in a cruise configuration tells the pilot which part of the POH applies and what the airplane should be doing.
Intuition Check
Do not read “configuration” as just the airplane’s general appearance. Here it means the actual flight setup: flap position, gear position if applicable, power setting, and control adjustment for cruise flight.
Example Sentence 1
After leveling off at 6,500 feet, the pilot reduced power, retracted the flaps, and trimmed the airplane into a cruise configuration.
Example Sentence 2
The airplane flew hands-off once trimmed for the proper cruise configurations at the target airspeed.
