LA Co Medical Helicopters
The last information I had was that LACOSO primary Puma ran out of Brackett Field in La Verne. They share quarters with LACOFD's east FireHawk (Blackhawk). My understanding valley floor calls go first to LACOFD, San Gabriel Mountain/LA National Forest to LACOSO.
My understanding that LACOSO staffs a second Puma at Long Beach as staff allows/special events. One spare.
LACOFD staffs a north helicopter and west helicopter (both FireHawks) on top of the east aircraft. The west helicopter moves back to Pacoima in the evening as it is subject to fog.
I thought LACOFD has four FireHawks with a fifth on order.
LA City FD runs at least one AW-139 out of Van Nuys. This is the same type of helicopter Maryland State Police is transition to. I have been told half a dozen stories about possible staffing of a second AW-139 for medical calls, so I am not clear what LA City FD is doing. FAA lists LA City FD with four AW-139s.
Each agency will handle others calls if aircraft is down, on call, multiple calls and so on. I understand they will call Ventura County Fire/SO's helicopter or San Bernardino County SO on occasion prior to calling Mercy Air.
My understanding Catalina Island calls go to the closest available public aircraft.
I am told the AW-139 for its size is produces little noise in-flight. Keeps complaints from the Hollywood Hills down.
