Not just the press making a meal out of the 146 APU - CAA AD002-03-01 came out this year, and Honeywell were swamped with U/S Aircon packs; so much so, that they've upped their Power by the Hour fee!!
As to the de-ice fluid, it runs down the fin when you de-ice, and what's at the base of the fin??? APU Intake!!!!!!!!!!! Takes about 30 secs to vapourise the water/alcohol mix, leaving a funny boozy smell on the flight deck......bit like when the crew are on board
There's a simple Mod out that introduces a little gutter above the intake - works quite well, apparently, so our mob are going to give it a try. Watch this space!
