What is the difference between best rate of climb and best angle of climb in an aircraft?
Best rate of climb speed, also known as Vy, is the speed which allows the best gain in altitude over a given time. You fly this airspeed when you want to gain altitude fast but you don't have any obstacle you need to avoid.
Best angle of climb, also known as Vx, is the speed which allows best ramp climb performance. You gain the most altitude in the minimum distance. Usually this airspeed corresponds to 1,2 times the stall speed and we fly it when we need to clear obstacles.
Vx is always bigger or, at the minimum, equal to Vy.

What is the difference between best angle of climb and best rate of climb in an aircraft?
Best angle of Climb (Vx) : Climbing at Vx allows an aircraft to maximize the altitude gain per unit ground distance. That is, Vx allows a pilot to maximize his/her/their climb while sacrificing the least amount of ground distance. Usually used for Short Field takeoffs to clear obstacles.Best rate of Climb (Vy) : Climbing at Vy allows an aircraft to maximize the altitude gain per unit time. That is, Vy, allows a pilot to maximize his/her/their climb while sacrificing the least amount of time. Usually used to get to altitude in the shortest amount of time.
Why is angle of climb speed lower than rate of climb speed?
Not so easy to awnser in short....It is difficult to understand the relation between Vx & Vy (Vx = best angle and Vy = best rate of climb), without first understanding the effect of drag on an aircraft. If you look at the relation of total drag/power available relelative to velocity, you can determine different kinds of velocities such as Vx and Vy.To achieve the highest angle of climb (highest nose position above horizon) for a propellor driven aircraft, you need the highest amount of power available of your engine. The highest power availability occurs at a speed which is lower than your minimal drag speed (Vmd), which would be your best glide speed or best rate of climb. At point Vx you have the most excess thrust availablewhich is the single factor enabling an aircraft to climb.Note that Vx is a lower speed than Vy, your best rate of climb! Considering this, an aircraft reaches an height faster with the best rate of climb, while Vx has a higher nose attitude! Practicle use would be, to avoid an obsticle you could use Vx, and climb at shorter ground distances etc. Note that the use of flaps increase your Induced drag because the increase of lift, thus changing the total drag (reduces drag speeds) curve and changing the whole Vx/Vy speed spectrum... :)
What is the rate of climb and rate of descent of a passenger airplane?
Depending on the aircraft but most jets and passenger aircraft have a safe climb speed of anywhere between 1800 and 3000 feet per minute. A safe and sensible descent rate for the same aircraft may be between 800 and 2000 feet per minute.
What effect will a elevon have to a aircraft?
An elevon makes the aircraft climb or dive.
How does wind effect angle of climb Vx?
Wind can affect the angle of climb at Vx by increasing or decreasing the groundspeed at which Vx occurs. A headwind will result in a higher angle of climb due to the reduced groundspeed, while a tailwind will result in a lower angle of climb due to the increased groundspeed. Pilots need to adjust their pitch attitude and power settings to maintain the desired angle of climb speed in varying wind conditions.
