Hi.Have just finished reading Paul Craigs "The Killing Zone"
For those not conversant with the book,it is by an American author,who has researched G.A. accidents in the States.
Basically he states(by figures)that the majority of fatal accidents occur between having 50-350hrs flight time experience-i.e.The Killing Zone.
On the whole it is worth a read,but the point of this thread regards what he says on the chapter on weather and in particular Carb ice
Quote
"I always operate with continuoes Carb Heat on when I am flying in visible moisture or cloud,rain etc.I also operate continuoes Carb Heat when the temp and dewpoint are within 5degrees of one anotheror relative humidity is above 90%
I was always taught that Carb Heat should only be used in moderation,i.e. FREDA checks,on approach(low RPM settings)and if you had a rough running engine.
I`m sure I also read a thread here that excessive Carb Heat could be a hazzard.
Not knocking the guys experience(flight instructor),but any comments anyone?
Safe Flying,
Bob.
