How do you determine your best climbing speed?
You can determine the speed for best angle of climb (VX) by drawing a tangent on the “Climb Rate v Airspeed” graph from the origin of the climb rate to the climb rate curve. Climbing at this speed will yield the greatest height gain per distance traveled.
How do you find vertical descent speed?
Vertical speed (ft/min) = Descent rate (%) x Ground speed (knots)
- Ground speed in some aircraft is not known because the wind is not known.
- Ground speed can change during descent if this speed is not maintained constant.
How to calculate minimum rate of climb for departure?
After obtaining the aircraft’s rate of climb and ground speed from the AFM we can calculate the required minimum rate of climb for the departure. To make our calculations easier there is a rate of climb table in the terminal procedures publication. The table normally begins with the standard climb gradient of 200 feet per nautical mile.
Which is true about the rate of climb?
For training purposes we considered the thrust as a constant. As you can see in the picture Rate of climb ( R/c) = TAS ( True air speed) * c, which is the same as R/c= TAS * (T-D)/W which is equal to R/c= (Pa-Pr)/W. Rate of climb will be the greatest when the relation Pa – Pr is the greatest.
What is the rate of climb per nautical mile?
The result will be the required rate of climb in feet per minute. If a climb gradient of 200 ft per nautical mile is required and our ground speed in the climb is 90 knots we will need a rate of climb of 300 feet per minute.
How to calculate the climb gradient on a plane?
After reviewing the aircraft flight manual we determine our rate of climb for today’s conditions is 850 feet per minute. Next we determine our ground speed is 70 knots. Referencing the climb gradient table we will need to interpolate. Notice the largest number we must interpolate between is 400 feet per minute.
