How a Machmeter Work

This video explains the principle of operation of the Machmeter, both analog (fed by the pitot-static system) and digital (fed by the air data computer). And it also highlights the importance of the MACH number when operating at high altitudes.

Thank you so much for your videos. They’re helping me a lot for my dgca papers

[@yashprasadh9492]

Airline paper 💀💀

[@АннаКонстантиновна-с3ч]

Just the best explanation I have met while studying for ATPL EXAMS

[@robertnowaczyk5847]

The most appealing and reasonable explanation of Mach and Machmeter I have ever come across. Thank you.

[@prasantha1452]

Thank you so much sir.. You are doing such a great thing.. Nowadays I'm preparing for my exams by watching ur videos only...

[@RohitKumar-sv5xx]

Amazing...ur contents cover all the topics in a very simple manner and easy to understand through pictorial representation and animations ...thanks alot sir

At 4:10 it is implied that Mmo must be lower than Mcrit by a "safety margin". Most jet transport aircraft are transonic. Mmo is greater than Mcrit for most jet transport aircraft. At 7:50 the correct definition of dynamic pressure is given. At 10:50 it is stated: "Total = Static + Dynamic". This equation applies only to incompressible flow and is approximately correct at low speeds. At the high speeds where a Mach meter is needed the airflow is considered compressible and at such speeds total pressure is significantly greater than the sum of static pressure and dynamic pressure. The equation at 10:50 is therefore incorrect in the context of the Mach meter.

[@muhammadjanjua]

Great sir ,what is the top of descend and bottom of ascend ?

[@phoonjzc]

6:46 why is the MMO red line equation is y= -x and not y = x ?

[@yiweizhang65]

8:50 The LSS is proportional to the **square root** of the ratio of Static Pressure over Density (Ps / ρ).

[@yiweizhang65]

Still very clear and well organized explaination to help understanding how MACH is measured.

[@kyleeames8229]

I’m surprised that the instrument uses pitot-static connections. I always imagined it worked by measuring the speed of sound in free air by pinging a forward mounted microphone with an aft mounted ultrasonic transducer.

[@jcc801]

8:54 there is a mistake. On the left side, the first formula should be ρ is proportional to Ps and proportional to1/T. But you can't say ρ is proportional to Ps/T. Because the first formula and the second are inconsistent. First formula shows that T is inversely proportional to Ps, but in second formula, T is proportional to Ps. Just doesn't make sense.

How does the aneroid maintain a constant 29.92 inHg inside and still have any interaction with the pressure outside of it?

[@jumb0j0ck]

It doesn’t. Although there’s a lot of good material here, there’s the occasional glitch. An aneroid capsule is calibrated to 29.92” Hg, but inside the capsule is normally a lower pressure than 29.92”, sometimes even a vacuum.
