Abstract

Wing in ground effect theory has been found and researched as along as since the 1920s. Known as WIG, it is a natural phenomenon where the lift-to-drag ratio effects the take-off and landings of an aircraft. WIG happens when the ground clearance, particularly when the distance between the aircraft and the ground is less than one wingspan, this phenomenon will occur due to the compression of airflow beneath the aircraft. National Transport Safety Board (NTSB) recorded the accident cases that happens around the world, and numerous cases have been found to be happened either during landing or take-off phase. The aim of this project is to study WIG and the principles behind it, and to determine whether this effect has a role to play in the chosen accident cases, particularly the cases during landing and take-off. Case studies on all the chosen accidents cases that will be obtained from NTSB official website will be studied in details and computational approach will be performed to identify the relationship between WIG and the accidents. Simulation on the parameter and data obtained from the accident report and from the manufacturer reference list will be ran and comparison is to be made between these two data. The expected output from this project and research is that the accident cases do not involve or, the WIG has not play any role in the cases, and the accident cases just happened due to inaccurate action taken by the responding pilot.
