Works out at about 2.6% of the total LAPD budget. In terms over arrests made, that wouldn't without the helicopter, safe conduct of pursuits, negative searches of crime scenes(which are a positive result, saving fruitless man hours of patrols on the ground) it has to be good value for the money.
As a comparison, the UK budget for 15 helicopters and 4 FW was $36.4M for 2022/23, and the cost per flying hour was about $3200.
