Recently was faced with FZ DZ and the company has standard policy of no departures in FZ RA. De-Iced using Kilfrost type 4 with 100% mix and this allows a departure in FZ DZ with a HOT of 40 minutes. Another question, can you land in FZ RA, most operators stipulate TO only as a No-Go? I'm not trying to be smart I honestly don't know and personally avoid freezing rain at all cost. I saw it at Anchorage once and it stuck to the wipers like super glue so you can imagine what it's doing to the wings. Great care needs to be taken in deciding the difference between DZ and RA, if you need the wipers don't go. 'Blind P' you say your operator allowed landing in freezing rain subject to braking conditions, I assume 'Good' was required?
