As we know Annual Reports are scarce and inconsistent in the information given ... but the 2015 version gives a grand total of 340 people directly involved [such as the Strategic Board members, maintenance organisation, PCC would be significant extras].
The numbers from that report state 180 TFOs and 87 pilots.
The 'compact' and less informative 2018 report gives the overall staff numbers as 332. Current Police Officer payscales are going to be variable but an example is given at

A lot has happened since the last report from NPAS and it has been promised for months now. I suspect that they may never appear.
