Student Pilot on a R44 Astro. Im gonna be doing some cross country this week and as cold as it is, its colder in the air. What are the effects on the engine or the fuel burn for leaving the carb heat on for extended periods of time. Does it reduce power a lot in the event of needing more lift in a hurry? Could you pull carb heat a third of the way?
This is not to say that I wouldnt be doing my regular checks anyway.
