The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tandem cockpit for a two-man crew. The Apache was developed for the United States Army to replace the AH-1 Cobra, and introduced to service in April 1986.
Initially the rotors are stationary, use the B key or triggger setting 2 to start or stop the rotors. The helicopter will lift and hover above the track, using the H key or trigger setting 1 – use the H key again to lower the helicopter. The maximum hover height is 15 metres, and may be varied in the config file, default setting 10 metres.
The helicopter is loaded with Hydra missiles in the two pods and the larger Hellfire missiles on the racks. These are all animated and cannot be changed by the user. There is also an operating M230 chain gun. The gun has a random animation when the helicopter is running.
The V key fires the missiles: first press pickles off six hydra, second press fires two Hellfire from the right rack, third press fires two Hellfire from the left rack, and the fourth press fires the chain gun. Subsequent presses recycles the sequence.
