What is the best angle of climb airspeed?
What is the best angle of climb airspeed?
Vx
An aircraft climbs because of excess thrust or excess power. Vx is your best angle of climb speed, and Vy is your best rate of climb speed.
What is true of the best rate of climb speed?
Best Rate-of-Climb:
- Best rate of climb, or Vy, maximizes velocity to obtain the greatest gain in altitude over a given period of time.
- Vy is normally used during climb, after all obstacles have been cleared.
- It is the point where the largest power is available.
- Occurs above L/Dmax for a jet.
- Occurs at L/Dmax for a prop.
What determines best rate of climb?
The sum of these two drag forces creates the aircraft’s total drag curve and is equal to the aircraft’s power required curve. The difference between power required and power available is excess power. The true airspeed that gives the maximum amount of excess power is an aircraft’s best rate of climb speed.
What is VX and VY in aviation?
VX and VY are arguably the two most important V speeds in all of aviation. VX is the best angle of climb and VY is the best rate of climb. In most cases, VY is used because it gets the plane to altitude the fastest. But if you need to climb more steeply, then VX is the best airspeed to use.
What is best angle climb speed on A320 21?
I have read about common climb rates for an A320. It is said that the initial climb rate for an A320 is between 15-20° and it differs depending on the weight and also the altitude….
- Usually you aim for climb speeds, the rates vary with air density and other factors.
- If I’m not mistaken, 15-20° is a climb angle.
What is the best rate of climb speed in a Cessna 172?

When would a pilot use the best angle of climb speed?
Best Angle of Climb speed (Vx) gets you the greatest altitude per unit of ground distance (feet per mile). When you’ve got a FAA-Standard 50-foot-tree at the departure end of the runway you’ll aim for the best angle of climb to ensure you don’t wind up in the tree.
What does the angle of climb depend on?
This relationship means that, for a given weight of the airplane, the angle of climb depends on the difference between thrust and drag, or the excess thrust (Fig. 17-56). Of course, when the excess thrust is zero, the inclination of the flightpath is zero and the airplane will be in steady, level flight.
What four main factors determine climb performance?
The climb performance of an aircraft is influenced by factors like: the amount of applied power, type of propeller, airspeed, drag in the form of flaps or landing gear and weight.
What happens to the speed for VX and VY with increasing altitude?
If Vy is measured as a true airspeed, it increases approximately 1% for every thousand feet increase in altitude. That’s right! If you measure Vy in terms of TAS it will increase, not decrease with altitude. Therefore, if Vy is 82 knots (TAS) at sea level, it must be approximately 90 knots (TAS) at 10,000 feet.
