I worked for Air Logistics. They didn't have a problem with my fixed wing experience. Neither one of the regionals I worked for had problems with my sling wing time. Majors have been a different story (CAL seems to be the most friendly of all-at least for military rotary types).
I flight instructed to build my initial starch wing time. Bouncing around in cessna 152's and 172's doesn't even compare with the rotary wing experiences I have encountered. That is: From a technical standpoint, the amount of SA that is required, and the high degree of CRM and crew coordination that is required. Hand flying an ILS in a light airplane is a piece of cake compared with flying an ILS in a rotary wing aircraft.
For some reason outfits like SWA or AA seems to think that doing multiple traffic patterns in a Cessna 152 is better time than flying night time combat missions, looking through a 1.5"x1" display positioned over a single eyeball and having that as your sole source to fly the aircraft with, and in the mean time trying to not fly into your wingman or the ground while trying to shoot the bad guy and not the good guy. Oh, and if those aren't enough compound complications, did I mention this thing was a helicopter too?
OH, and for you guys who didn't get the jist of the thread; nobody here is saying that helo time should count the same as Part 121 turbojet time. But come' on, Cessna 152 time being counted as total time and not decent helo time? Maybe I could understand this if a guy was giving $20 dollar helo rides in a Bell 47 at the yearly county carnival and that is what the bulk of his helo time consisted of.
This pervasive mindset is pretty dam stupid if you ask me.
