The most important speeds in aviation (aviation explained)

In aviation there is not only one speed that is important. In this video I explain the most important speeds such as: Indicated Air Speed (IAS), Calibrated Air Speed (CAS), True Air Speed (TAS), Rotation Speed ( VR), Decision Speed (V1), Climb (Safety) Speed (V2), and there dependancies to the Critical Engine Failure Speed (VEF), Lift Off Speed (VLOF), Maximum Brake Energy Speed (VMBE), Minimum Control Speed Ground (VMCG) and Minimum Control Speed Air (VMCA). I also explain the correlations and prerequisites. Enjoy the video.

Hi Salma, thank you. My general plan is to do both languages. The "professional aviation" topics, I will speak only in english.. I wish you a great day, Frank

Can you tell me the difference between the civil aviation V1 and the military refusal speed of the military aircrafts ?

[@operationgoldilocks2481]

Where can we find why V(NE) varies with altitude?

Guten Tag Kapitän Dreyer,wieviel kg/Stunde Treibstoffe verbraucht der A380 im Durchschnitt für Reiseflug?

What is optimum V1?

[@CaptainFrankDreyerA380]

There is no „optimum V1“, the V1 is a calculated speed dependent on many conditions, i.e airport elevation, rwy lenght, meteorological conditions, Take off weight/thrust performance, to name a few. For this reasons, V1 is named a decision speed
