Is Vy a function of Pressure Altitude Only?
Preface:
This question is about Vy in KIAS - not Rate of Climb. I understand that ROC is a function of pressure altitude and temperature (density altitude)
This question is regarding knots INDICATED ...

Why doesn't pitching up above vx result in a better angle of climb
Like technically, you could pitch up higher. I have drawn a (greatly exaggerated) picture to show what I mean.

Under what conditions can the maximum angle of climb be achieved for jet and propeller aircraft?
I know that the maximum angle of climb is reached at maximum specific excess thrust (S.E.T.) for jet airplanes, or minimum drag or maximum $\frac{L}{D}$.
Is this true, and if yes, is this valid also ...

What's the minimum climb gradient when the MEA changes without an MCA?
If the MEA changes at a navaid, fix, or waypoint along an airway, and there is no MCA, you can begin the climb to the new MEA at the fix. I was wondering what minimum climb gradient is assumed by the ...

For a fixed density altitude, how does climb performance depend on pressure altitude?
Below is the climb performance from the 1978 Cessna 152 POH, which I've plotted as climb rate versus density altitude. It shows that higher pressure altitude gives decreased performance even when the ...

Are these IFR Pattern colors following a standard?
I recently came across a series of IFR practice patterns such as the example below that use red for descent and blue for climbs.
Are these colors standard in the IFR world or was it just made up for ...

Climb angle relationship to excess thrust
In the PHAK, Chapter 5 Aerodynamics, the following statement is made regarding forces in a climb:
The thrust required for a stabilized climb equals drag plus a percentage of weight dependent on the ...

Does lift equal weight in a climb?
This subject keeps coming up in the discussions and questions such as this one, which asks if lift equals weight in level flight. Good answers there, pointing out that upwards force has many sources. ...

How can I control the flight path angle (or the ROC) with throttle in Simulink?
I need to implement an autopilot for my 3DoF (longitudinal motion) aircraft model in Simulink. My model is nonlinear, but linearizing it in Simulink hasn’t been an issue.
I’m trying to develop a ...

How does changes in Power vary the aerodynamic forces on an aircraft?
When we make changes to the Thrust by adding or removing power. In what way does it affect the other forces? As Power controls Rate of Climb or Descent of an aircraft, How is it acting on the other ...

Why does the climb angle of 737-800 peak shortly after take-off before reducing again?
I am doing a report on 737-800 and I have questions about its climb angle performance;
I am plotting a climb angle VS altitude graph for the aircraft, why does the climb angle take off at an angle and ...

Steepest climb a wingsuit pilot can achieve?
There was a question yesterday about landing in a wingsuit; the main issue is, of course, the high speed, both vertically and horizontally. One way to reduce speed is flaring; another would be to gain ...

How is Vx speed and Vy affected when climbing?
If my speed for best angle of climb is 60 and rate is 79, if I kept a 500 fpm climb to my cruise altitude of let’s say 4500, would those speed change?
The flights are being done on separate occasions.
