My trusty little C172H has been flying for 45+ years now with me flogging it for the last 10 or so, and I must report it is a right bitch with carby ice, to the extent that I personally instruct anyone that fly's it on the NEED for carby heat in any situation that the engine is under 1500 rpm, having done this for the last 45 years she manages to stay airbourne with her lumpy TCM six cylinder donk rattling away. Well done to the pilot for managing to survive this accident and may you continue to persue your dream.
cheers
A172
