Definition
A category of aircraft performance data showing how the airplane behaves during the cruise phase of flight, including expected true airspeed, fuel consumption, and the distance the airplane can travel for a given fuel load at various power settings, altitudes, and atmospheric conditions.
Plain English
Information that tells you how fast the airplane will fly, how much fuel it will burn, and how far it can go during the level part of a flight.
Context Anchor
Seen in aircraft performance charts when planning the cruise part of a flight, choosing an altitude, estimating fuel needed, or deciding whether a fuel stop is required.
Derivation
Cruise' comes from the Dutch 'kruisen,' meaning to cross or move steadily. 'Range' comes from Old French 'range,' meaning a row or line, and later the distance something can travel. Together they describe steady-state flying and how far that flying can take you.
Why Pilots Care
Directly affects fuel planning, altitude selection, and whether a flight can be completed without refueling.
Grounding Statement
This is the planning information that connects airplane speed, fuel burn, and travel distance during the main level part of the flight.
Intuition Check
Do not read “performance” as a general judgment that the airplane is good or bad. Here it means specific expected numbers: speed, fuel use, time, and distance under stated conditions.
Example Sentence 1
Before the cross-country flight, the pilot reviewed the cruise and range performance charts to select the altitude and power setting that would give the best fuel economy.
Example Sentence 2
By adjusting power settings according to cruise and range performance charts, the pilot extended the aircraft’s distance on the available fuel.
