Airro Refuel LearJet
Read full descriptionHide full description
Handy tool for refueling a LearJet35 aircraft. The required fuel distribution is calculated based on the input values lbs or liters. The cumulative fuel amount is calculated to verify that the amount corresponds with the fuel truck gauge. The values of the fuel stages are graphically shown. I build this tool to quickly make the calculations and show the fueler in an easy way how to refuel this airplane.
