Cruise, Lesson 8
 
Small aircraft in flight

The information in this video was accurate as of the original publication date.

Audience: Educators and Students
Grades: 9-12


This NASA video segment explores how Newton's laws can be used to assess an airplane's cruise performance. By watching an instructor at NASA's National Test Pilot School, viewers learn how an aircraft's cruise performance is evaluated and how this performance can be maximized. Viewers also learn how to rearrange the lift and drag equations to find the ratio of the coefficient of lift to the coefficient of drag that will provide maximum performance. Using a graph of these coefficients, the instructor demonstrates how to solve for the maximum endurance speed of the plane and then tests the calculation in an airplane.
