The sheriff's aircraft have a green and gold color scheme, with a lime green and yellow stripe. They also have a Sikorsky UH-3H Sea King and a Eurocopter AS332 Super Puma that are suitable for rescue use.

The LA County sheriff has more than a dozen helicopters, mostly Eurocopter AS350s. Their helicopters have a distinctive look and sound due to their lack of tail rotor blades. The Burbank and Glendale police have a joint Air Support unit that flies 3 MD520 helicopters, which often fly over the northeastern parts of LA, like Eagle Rock. Most of LAPD's aircraft are based out of the Hooper Heliport. LAPD uses two different paint schemes: A two-tone, dark blue and silver, or a newer scheme reflecting the traditional black and white patrol car. Most of LAPD's choppers are Eurocopter AS350s but there are also a few Bell 206 models in the fleet.

LAPD alone has almost 20 helicopters, making its Air Support Division the largest municipal airborne law enforcement operation in the world, and there are almost always at least two, and sometimes three, police helicopters on patrol at any given time. The Eurocopter AS350 is the most popular model among police agencies, with the occasional Bell 206 and MD500 showing up as well. Most, but not all, of the police helicopters in the area have a registration number that ends with 'PD' or 'LA'. The city's large size, bad traffic and sometimes rough terrain make helicopters a practical way to get around the city quickly for public safety, news and medical personnel.
