GTA III's flight*.dat map
Vice City's flight*.dat map

The flight*.dat files controls the movements of NPC flying vehicles in GTA III and Vice City. These files are located in the .\data\paths folder in the GTA III and Vice City directories. The following files control these flying vehicles:

GTA III Vice City
flight.dat Airtrain
flight2.dat DeadDodo
flight3.dat DeadDodo used in "S.A.M." Police Maverick
flight4.dat DeadDodo used in "A Drop In The Ocean"

These flying vehicles are not solid so you cannot collide into them and there are no drivers in them. DeadDodos can be destroyed by shooting a rocket through the plane. In an early GTA III commercial, the Airtrain is seen being destroyed by the rocket. This feature can be enabled through Silent's "Destroyable Airtrain" mod.

Format

GTA III Vice City Type Description
Section 1: Number of path nodes
A integer The number of lines that are to be read from the file.
Section 2: Path nodes
A,B,C float[3] X, Y, Z coordinates, each line linked to create a path

For flight.dat in GTA III, if the point is below the ground, the game internally replaces the z-coordinate with the ground z at that point. In Vice City, the game internally replaces any z-coordinate below 14.0 with 14.0. This is primarily used to determine the landing and takeoff points and allow aircraft to taxi on the surface.
