Carb ice checks - How often?
Having flown on Saturday in lovely but serious icing conditions (as defined by safety sense leaflet 14A) I experienced mild carb ice in the cruise. I was checking every 5 minutes or so and leaving it hot for a good 15 seconds.
This got me thinking whether every 5 mins is enough. I tend to be a bit paranoid about carb ice and though every 5 mins overkill but saturday taught me otherwise.
What's your carb ice routine?
