Hi,
take care about the different regulations regarding icing in FAA and EASA regions.
Incomplete listing:
NOT Known Icing (as far as I know)
TKS:different Beech Bonanzas, Socatas and some Cessnas
Boots: Silver Eagle P210 with Allison, C337
Known Icing:
- Some Mooneys with TKS ( Known Icing when factory equipped, not so if aftermarket)
- Piper Malibu/Mirage(/Meridian/Jetprop)
- Cirrus SR22
I would strongly suggest to take a close look at performance in icing conditions. The the de-icing and anti-icing equipment in _every_ plane is not a solution to stay in ice but to sustain the options of climbing/descending/manoeuvering out of the ice...
Keep in mind that especially piston equipped airplanes are not famous for there climbing ability in the flight levels with ice on the unprotected areas... Additionally there's usually not a lot of redundancy in these systems.
Kind regards,
Peter
