180 Challenger Fuel burn
It looks like the book shows 9-10 gph for burn for cruise. I don't have fuel flow yet but plan on getting one. What numbers do you use for flight planning which would include start, taxi, and climb to a typical 5000-8000 ft cruise? What do you see in climb? Do you have a first hour number? and then a second hour number? Do you use something like 12-13 per hour for a 2 hour trip?
