Definition
The maximum distance an aircraft can fly on a given fuel load, measured from takeoff to fuel exhaustion, without regard to reserves required for safe arrival, holding, or diversion to an alternate.
Plain English
The farthest an aircraft could possibly fly before it runs out of fuel, with nothing held back for safety margins.
Context Anchor
Seen in aircraft performance, flight planning, and fuel planning discussions.
Derivation
From Latin totus, meaning whole or entire. Total range is the whole distance the aircraft can cover, before any fuel is set aside for reserves.
Why Pilots Care
Determines whether a planned route can be completed safely with required fuel reserves, directly affecting go/no-go decisions and alternate airport selection.
Intuition Check
Do not read “total range” as the distance you should plan to fly. It means the full possible distance under assumed conditions; safe planning normally keeps fuel in reserve.
Example Sentence 1
The aircraft's total range was listed as 800 nautical miles, but with required reserves the pilot planned for no more than 650.
Example Sentence 2
After adding the required fuel reserve the pilot recalculated the total range and chose a closer alternate.
