FarmVille Biplane Flight Cost Formula

This week the FarmVille Biplane was introduced. The Biplane can be purchased for 30,000 coins and will instantly fertilize your entire crop with Insta-Grow. While the first flight is free, additional flights will cost varying rates of farm cash depending on how much time is remaining until your crops are ready to harvest.

There is no set price as it dependent on several factors including what crop you are growing, the time remaining, and how many plots you have.

FarmVille Freak Ingeborg hypothesizes that there is a formula used to calculate the cost of Biplane flights. Here is her thoughtful explanation described below. Thank you for sharing with us FVFreak Ingeborg.
