Average Acceleration Calculator

In flight mechanics, “average acceleration” denotes the average rate of change of an aircraft’s velocity over a specified time period. It serves as a crucial parameter in analyzing the dynamics of aircraft motion during different flight phases, such as takeoff, climb, or descent. This acceleration is computed by dividing the change in velocity by the corresponding time interval. Understanding average acceleration is essential for assessing aircraft performance and maneuverability, and the forces acting upon it throughout flight operations. It directly impacts factors like takeoff distance, climb rate, and overall flight efficiency. The formula to calculate average acceleration is as follows:

Where:

  • g is the gravity in m/s2.
  • W is the weight in N.
  • Tavg is the Average Thrust in N,
  • Davg Average Drag force in N.
  • Lavg is the Lift Force in N.
  • μr is the rolling friction coefficient.
