Ground support equipment ( GSE) is the support equipment found at an airport, usually on the apron, the servicing area by the terminal. Fig: Component of Towing Force Total Towing Force, FTOT = Wind Force + Wave force + Current force. This means that when the tow car brakes, the inertia of this force prompts the application of what is known as the ‘overrun brakes,’ which are installed to reduce the brake effort carried out by the tow car. One important difference is that normal force is a vector, while the newton is simply a unit. The calculations behind this look as follows: P (kW) = F (N) x V (metres/min) / 1020 x 60 In which P = power in kW, F = Force (line pull) in Newton, V = Line speed in metres/min, 1020 is a constant and 60 is a translation from minutes into seconds (Nm/sec). • Theoretical horizontal force between towing vehicle and trailer • The D-value can only be calculated with the permissible total weight of both truck and trailer • Calculation of the D-value (kN): The calculated D-value can be equal to or lower than the D-value of the hitch and of the towing eye.
