Flight Time Formula:
| From: | To: |
Aviation flight time refers to the duration required for an aircraft to travel from one point to another, calculated based on the great circle distance between points and the aircraft's cruise speed. This calculation is essential for flight planning, fuel management, and scheduling.
The calculator uses the flight time formula:
Where:
Explanation: This formula provides the basic flight time calculation without accounting for factors like wind, taxi time, or air traffic control delays.
Details: Accurate flight time calculation is crucial for flight planning, fuel requirements estimation, crew scheduling, and ensuring compliance with aviation regulations and safety standards.
Tips: Enter the great circle distance in nautical miles and cruise speed in knots. Both values must be positive numbers. The result will be displayed in hours.
Q1: What is a great circle distance?
A: Great circle distance is the shortest distance between two points on the surface of a sphere, following the curvature of the Earth.
Q2: Why use nautical miles and knots in aviation?
A: Nautical miles and knots are standard units in aviation because they relate directly to navigation and the Earth's coordinates (1 nautical mile = 1 minute of latitude).
Q3: Does this calculation account for wind?
A: No, this is a basic calculation. For actual flight planning, wind components (headwind/tailwind) must be considered to calculate ground speed.
Q4: What factors can affect actual flight time?
A: Wind conditions, air traffic control routing, altitude changes, taxi time, and weather deviations can all affect actual flight time.
Q5: How accurate is this calculation for flight planning?
A: This provides a baseline estimate. Professional flight planning includes additional factors like climb/descent time, alternate routes, and fuel reserves.
