What equations and constants did they use to build the E6B flight computer?

Don't bother with E6B-slider variant. I used it for my PPL theory. But later I discovered that the E6B-Circular is much better in any way. I then used the asa2fly.com/circular-e6b-flight-computer for ...

How does maximum speed vary with altitude?

Let's apply general (...and simple) knowledge from ATPL: There is a relationship among TAS-MN-CAS The graph above can be used as a handy guide to the relationships between the speed references. Of ...

How does maximum speed vary with altitude?

From sea level to Ionospheres, it first increases because air drag decreases with altitude, until at a certain altitude the maximum velocity starts to decrease because engine performance decreases.

Airspeed change in wind shear

Let's consider a simple example: you fly at a true airspeed (TAS) of 100 kt with a tailwind (TW) of 20 kt. This would result in a ground speed (GS) of  \text{GS} = \text{TAS} + \text{TW} = 100 \, \...

TAS from POH or e6b

Using the POH with a fixed power setting is more correct, and as a student, you should absolutely do it that way. The POH is where you get your fuel burn per hour. That, combined with GS and ETE per ...
