Abstract: An aircraft pass through various phases of flight during operations but landing phase may jeopardise flight safety, if executed inefficiently. Various factors may compromise a safe landing but wind disturbance is unpredictable and difficult to handle during the landing phase. This study provides an insight using mathematical modelling into flight handling issues of an aircraft during landing under the influence of disturbances caused by wind while considering pilot input as an important factor for the handling issues. A mathematical modelling using equation of motion for a transport aircraft has been carried out to study gust profile and its effects on aircraft flightpath during lading. The numerical analysis includes a detailed parametric study of the effect of gust frequencies and amplitudes to aircraft handling technique during approach and landing. The vertical gust disturbances have more effects on the flightpath than the disturbances caused by a horizontal gust during landing and descend.
