CRP-5: Mach number & the speed of sound

[@PedroThePortuguesePilot]

What a legend, great video. Thanks for that

[@Kev_Ridge]

You are truly a legend. Thank you so much for your videos, they are quality!!

[@gwadalondon]

Great video and explanations, mate; thanks

[@deago444]

best video seen so far for crp 5

[@Aleksej-K]

Thanks mate,good explanations :)

[@jorgepleal]

Thanks!

[@devildog1285]

Thanks!! Helped me a lot!!

Hi, can You Kindly explain why when we are flying at a constant altitude with a constant Mach, the CAS remains the same, and vice versa? Thanks!

[@Goproflying]

Saurabh Kumar as long as you are at a constant altitude the air density is assumed to be constant. As CAS if effectively based on dynamic pressure, it won't change. Only the altitude will change the airspeeds due to a difference air pressure. Temperature changes will also have a small impact.

An aircraft is flying at FL 440 with a TAS of 505 kt . OAT IS ISA - 10 C . What is its Mach number ?? Can anyone know how to make it ??

[@luistavares5620]

at FL440 EASA uses the Rule "Upper than FL360 temperature is roughly constant at -56.5)

[@slydesplaylists]

at 13 c this makes for 658.5 knots kts which is the LSS speed of sound . What is (K)38.84 derived from. Planc perhaps 6.62607004 × 10-34 m2 kg / s being the constant the mass weight redux so 20.01 (mps) would be more convenient with less mass velocity of G forces dependant on true motion of our solar massive and the atmospheric velocity for advanced design concepts in faster true speeds at lightspeed aside there coukld be a laser verion of this dial ,strobing mabye nice app can you get it anywhere I want a starforce too.

[@Goproflying]

If we start with the LSS calculation in m/s using 20.01 (still not sure of where that comes from) the value of 38.94 is simply the conversion to knots. Meters in a nm = 1,852, and seconds in an hr = 3,600. So, (20.01/1,852) x 3,600 = 38.89. Close enough

great video! 10x

[@SaurabhKumar-hr7fn]

Do you have any videos or the wind side for CRP 5?

[@Goproflying]

Saurabh Kumar my computer is currently dead and I don't have the software anywhere else. I will be doing a full series at some point on the wind side.

TY!!
