Examination of takeoff and landing


 For your independent project, create an instructional presentation. This assignment utilizes two independent examples - For the takeoff performance portion, you will utilize a generic example, while the landing portion is conducted specifically for your team's Cessna 172 project aircraft.

  1. Takeoff (completed using a generic example)
    • Utilizing Figure 10.1 (Dole et al., 2017, p. 162) explain on a selected example (not necessarily your team's selected project aircraft) how takeoff performance data in tabular and graphical form (as can be found in the flight manual/POH) can be used to determine the specific parameter:
      • Takeoff speed for a selected takeoff weight
      • Length of the takeoff roll
      • Distance required to clear a 50 ft obstacle
    • Using the same example, explain (backed by specific example data) how environmental conditions influence the takeoff distance.
  2. Landing (completed using your specific project aircraft)
  • Approach speed for a selected landing weight
  • Drag during landing
    • Total drag at touchdown (stall speed)
    • Average drag during landing roll (based on total drag at stall speed - Resources and Inputs)
  • Residual thrust
    • Residual power based on the rated power of the aircraft
    • Thrust at touchdown
    • Average thrust during the landing roll
  • Average deceleration during the landing roll
  • Length of the landing roll

Once you completed your specific landing case for your aircraft, discuss and support numerically (where appropriate) the following aspects:

  • Influence of altitude on landings
    • Influence on landing speeds
    • Influence on landing distances
  • Difference between landing roll length (as calculated above) and landing distance (as published in a POH)
  • Influence of landing conditions such as runway material and surface condition, runway slope, wind conditions
  • Influence of weight on landings
    • Influence on landing speeds
    • Influence on landing distances
  • Critical evaluation of any factors that were not considered in your example

As previously stated, you are encouraged to utilize appropriate computational software such as Excel® or MatLab®
