  • Page 33: Exercise 4: Creating A Report

    Exercise 4: Creating a Report In this exercise, you create a report based on observed data for a specific airplane’s power-off glide performance at several speeds. You then plot the data, perform a statistics regression, and estimate the speed that will produce the minimum sink rate for the plane.

  • Page 34: Entering The Data

    Entering the data TIP: The tabs at the bottom of the editor let you switch quickly among list editing, matrix editing, and spreadsheet operations. Airspeeds (L1) Sink Rates (L2) 30 mph 600 ft./min. 40 mph 550 ft./min. 50 mph 700 ft./min. 60 mph 875 ft./min.
