time to point of no return = (O H) E H + × E = safe endurance / H = groundspeed home / O = GS out the greatest distance to PNR/PSR is obtained in still air conditions. ETP (equal time point) or CP (critical point) = for quickest way home determination. distance to CP = (O H) D H + × D = total track distance / H = groundspeed home / O = GS out
6 maj 2024 · You may calculate the time of flight of a projectile using the formula: t = 2 × V₀ × sin(α) / g. where: t – Time of flight; V₀ – Initial velocity; α – Angle of launch; and; g – Gravitational acceleration.
Time of Flight. The time of flight of a projectile motion is the time from when the object is projected to the time it reaches the surface. As we discussed previously, \(\mathrm{T}\) depends on the initial velocity magnitude and the angle of the projectile:
Flight planning is the process in which a pilot prepares for an upcoming flight. While often associated with completing a navigation log for a cross-country, flight planning is a process that must be conducted even for local flights in the traffic pattern. It is a descriptive process therefore involving more than one type of navigation.
When a constant value of gravity is to be used (e.g., in a simulation), the value at 45° latitude is taken as the standard value of gravity (actually defined to be 9.80665 m/s2). Our simplified “flat-Earth” equations of motion will use a g vector that has only a down component, and is measured at the Earth’s surface.
24 wrz 2014 · Time between 2 points at a given ground speed (leg time) This is a common operation that needs to be done to fill out a Nav log or during a diversion in the air. Typically, time is though of in seconds, minutes, and hours rather than percentage of hours (1:20 rather than 1.33 hours).
It is calculated as follows: .117*distance – .0255*westmiles+ .00144*westmiles*(90-latitude of midpoint)^2 – .0000146*westmiles*(90-latitude of midpoint)^2 + 43.2. In this formula, latitude of midpoint is the latitude at the midpoint of the journey (using a great circle route) and westmiles is the number of miles traveled westbound.
