Some of you guys/gals should read the safety sence leaflets and have a good look through the AIP/AIC. Here is just one quote:
'Most of the time snow, which is already
frozen, will not stick to an aircraft, but
occasionally wet snow with a high
moisture content will stick. Treat it like ice.'
This is not to mention a whole host of reasons why flying an aircraft that is not certified to fly in known icing conditions into such conditions is nuts. how about engine icing, stall warner icing, landing gear icing, windscreen freezing, etc, etc.
how can you tell when flying into a shower (cu, tcu or cb) whether the snow will be frozen/moist/sleet or not, when the conditions under such a cloud may be turbulent, with updraughts/downdraughts, pressure changes, temperature changes etc. remember super cooled water droplets?
In answer to FFF's question - if it is not certified to be flown into known icing but you do anyway it is not legal. it is also not safe.
