Determine the following factors about your flight: The geographic distance in miles that you will be traveling, the planned speed of the jet and the force and direction of the wind over the course of your flight. Talk to the staff and pilot, look at a map and consult weather services.
Calculate the flight time without factoring in the wind conditions. Divide the number of miles to travel by the expected speed of the jet.
Calculate the speed with the wind conditions factored in. With your map and protractor, calculate the angle at which the wind will be hitting the plane as you travel between destinations. Place the bottom of the protractor along your plane's route toward its destination and draw a line inside the protractor in the direction of the wind. This line will point toward the angle of the wind.
Calculate the cosine of the wind's angle using a calculator by hitting the "Cos" button, entering the wind angle number and hitting "=".
Multiply the number from Step 4 by your flight time answer from Step 2.
Add the total number of miles traveled from destination to destination with your answer from Step 5. This will give you the total air miles of your flight.
Divide the air miles answer from Step 6 by the flying speed of the jet, which can be obtained from the pilot. The answer will be the approximate flight time for your private jet flight.
