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.
