How to calculate the real Ground Speed from True Air Speed?
In most of the formulas I've found online GS = TAS + Vw, i.e. true air speed plus wind.
However, on the simulator, GS changes drastically if I dive or climb which is obvious because I'm covering 0 ...

How to calculate Equivalent Airspeed immediately from Calibrated Airspeed?
I want to calculate each step like IAS -> CAS -> EAS -> TAS
as a chain. Each chain step should depend on the previous step.
IAS is clear. This is a function of pressures. With the Bernoulli equation, ...

Why is it safe flying in a tailwind when taking off is not? [duplicate]
If taking off in q tailwind is unsafe (due to loss of lift from reduced air speed), then why is it safe flying in tailwind, such as in jet stream?

What should be the minimum time spent in cruise (for e.g. a B737)?
Having a short sector to fly, it would not be convenient to climb all the way up to the best cruise altitude, since the time in climb would burn more fuel than that necessary for a flight at lower ...

Ground Speed vs True Airspeed from Departure Point to Destination - time interval
Looking at navigation theory right now and I'm stuck in the understanding of TAS and GS. How does GS determine the time interval it takes for an aircraft to fly from the DP to the DEST, if TAS ...

How does a jetstream boost an aircraft's speed? [duplicate]
Jetstreams are streams of high-moving west-to-east winds (200mph to 300mph, source) which most pilots are trained to use to cut down on their fuel costs (source). In the same linked article, it ...
