WMUSIGPI said:I do know that the citation 500 series couldn't use type 4 because of the slow Vr speeds and therefor could not take off in any type of freezing rain legally at my old charter company. (not to say others didn't do it)
Flightinfo has long since ceased to be a source of valid flight/aeronautical info.
Someone will make an issue of you flying a 1900, that you might be with GIA, might be paying for a job that someone else could be doing for a salary, which are all valid points.
Okay don’t crucify me on this one. I am just asking because, I, unlike some pilots, am not super be1900 pilot guy. I can swallow my ego and ask a question to those who have more experience and knowledge.
I know the FAA will not alloy any AC to operate in “severe icing” thus the FAA has qualified “freezing rain” as severe icing. That is understood but why do I see hold over times for light freezing rain. At my company we are not allowed to operate in -FZRA, when asked why not the answer I get is no plane is authorized. Well why do I see a hold over time for it on the FAA published hold over times. I have no problem not flying in this crap, but I am just curious if any airline has the ability to operate in –FZRA. Just a question on the procedures if allowed. I am just trying to learn something I am not trying to fly in this weather or think we should just looking for some answers
t8 thanks for the insight,
I am very familar with our ops/om1 taught it for 4 years, there is nothing on operating in -fzra. just fzra and standard icing conditions.
the one thing we dont have is the threshold temp requriement. that sounds like some data we should research. thank you for your imput
Thats kind of interesting. I flew the King Air series and the 1900 and always used freezing OAT plus 5 degrees (ram air temp...you know, she's so fast) in visable mositure. Eventually went to a straight 10 degrees C as a threshold icing temp. I'm surprised this isn't addressed in your FOM, especially after the inflight icing upsets of the Eagle ATR-72 (Roselawn?) in the 1990's and Comair's Detriot crash in 1997, all icing related crashes.
I'd do a little more digging. I'm pretty sure there is a threshold temp somewhere.
