THE ENG WAS STARTED & RUN TO 1500 RPM WITH NO PROBLEMS NOTED, EXCEPT THAT IT COULD NOT BE OPERATED AT A HIGHER RPM DUE TO A BENT PROP. THE TEMP & DEW POINT WERE 78 & 77 DEG, RESPECTIVELY. ACCORDING TO ICING PROBABILITY CHARTS, SERIOUS CARB ICING CONDITION WOULD HAVE EXISTED AT IDLE POWER. HOWEVER,THE CFI STATED THAT THEY HAD USED CARB HEAT ON THE DOWNWIND OF EACH PATTERN, THEN PLACED IT IN COLD FOR EACH TAKEOFF.
