The Air Ambulance shares the same helicopter design as the Armadillo (barring a different livery), thus being based on the Bell 412. Like the Armadillo, the Air Ambulance is a relatively large helicopter that nevertheless possesses relatively good speed, with moderately steep pitches that help increase its acceleration at the expense of losing altitude faster. During the creation of Vice City, The Air Ambulance was going to be made as the Coastgard Maverick but was cut after the alpha version.
The Air Ambulance can be used to activate Air Rescue side missions, the airborne equivalent of the Ambulance's Paramedic side mission. Completion of the side mission will boast the player's maximum health.
Both sides of the Air Ambulance's nose bear cursively written text. Due to the poor quality of its texture, the words are somewhat hard to identify.
"VCS - 911" is also written on both sides of the helicopter at the turbine engines. 911 is clearly referring to the main emergency number in the United States, but the "VCS" abbreviation, whether coincidental or not, is also a short form for GTA Vice City Stories' title.
Although the Air Ambulance does have non-driver seats, they are inaccessable (same goes for the Armadillo). So it is really only a one man vehicle.
