What is the difference between Best Rate of Climb and Maximum Rate of Climb?

Is there a difference between Best Rate of Climb and Maximum Rate of Climb? From my research, best rate of climb trades ground distance for altitude (i.e. steeper climb, more altitude per unit time)...

Does an accelerating airplane also start climbing?

Assume that an airplane is flying level. If I understood correctly in this situations there are four forces acting on it: weight, thrust, drag and lift. Lift depends on air density, airspeed, wing ...

How does climb-rate vary with density/pressure altitude?

I'm seeking to write a little web or phone app which can help me choose the best cruising altitude based upon winds aloft. I know Garmin Pilot (and probably Foreflight) have a cruising altitude ...

In a jet, are Vy and Vx achieved at a constant AOA at all altitudes?

In terms of IAS, Vx (best climb angle speed) increases with altitude, and Vy (best climb rate speed) decreases with altitude, until they meet at the plane's absolute ceiling. http://cospilot.com/...

How to find total climbing time based on Rate of Climb?

I am unsure on how to solve this problem. The only clue i have is to integrate ROC to find time. A jet aircraft has the capacity to fly at an absolute altitude ceiling of 11000 m, and a rate of ...

Is it possible to determine the approximate climb rate of an aircraft knowing its top speed, engine power and weight?

Is it possible to determine the initial climb rate of a craft with a few key pieces of data such as top speed, engine power and weight? For example the XB-42 was an experimental bomber design from ...

Does climbing or descending affect the rate of turn?

In the past, I used to have this idea that if all other factors remain constant, then climbing increases the rate of turn while descending decreases it. This idea was most likely planted into my mind ...

Is there an aerodynamic force that would keep this experimental WW2 era prop from flying as fast as an early jet?

The XB-42 was an experimental bomber developed during WW2. Its twin engines delivered a combined 3,800 HP and top speed of 410 mph at 23,440 ft. It's an amazing aircraft. But if an enormous ...

Why does Vx have a relationship with thrust but Vy has a relationship with power?

https://www.boldmethod.com/learn-to-fly/performance/vx-vy-altitude-and-where-they-meet/ After I watch this article, now I understand the relationship between altitude and the rate of climbs. But I ...

How to determine climb performance for various flight speeds?

I have the following climb performance chart: and I need to evaluate the maximum rate of climb in different flight conditions. The problem is, this chart is valid only for 85KIAS. Is there a way to ...

Can briefly explain the principle behind the inversion on this power required curve?

I’ve noticed on several graphs in the “Advanced Pilot’s Flight Manual”, that power available is lower for any given speed at 10,000 feet as compared to sea level flight. The power required curves ...
