Definition. Used correctly, rules of thumb (sometimes know as “heuristics") can assist significantly in pilot decision making and understanding. A rule of thumb is a principle with broad application that is not intended to be strictly accurate or reliable for every situation.
11 kwi 2023 · Distance, Speed, and Time. One of the most fundamental aviation math formulas is the Distance, Speed, and Time formula (DST). It is used to calculate the time taken to travel a certain distance at a specific speed. The formula is: Time = Distance / Speed.
The CAFE Foundation was begun more than 30 years ago to evaluate a broad array of aircraft technologies, and it came up with its own mathematical formula to judge aircraft efficiency. (Speed times 2.25/Fuel Flow times Payload)
Students calculate the distance between coordinates and use the speed formula to determine time, distance, or speed. Through this lesson, students are introduced to the concept of Advanced Air Mobility, or AAM, and air metro services.
Formula: Ground Speed (GS) (knots) ÷ 60 * Climb Gradient (Feet Per Mile) Example: Ground Speed = 75 knots; Climb Gradient Required = 200 feet per mile; Calculate: 75 ÷ 60 * 200 = 280 feet per minute climb rate required
Time, Distance, and Speed Calculations: Utilizing a simple formula (Distance = Time x Ground Speed may be utilized; Therefore, if you have any two, you can calculate the other; Time Calculations: If you need to travel 10 NM, and you have a ground speed of 100 knots, how long will it take? 10 NM = Time (hours) x 100; 10/100 = Time; Time = 0.1
To determine how long it will take to get somewhere, distance/time/velocity calculations are simple, and the engine performance is chiefly a function of the vehicle speed.
