I'm not even training to be a pilot but I enjoy his teaching method, simple and effective and he makes it clear that you need to understand what PA is. Cheers from California Dan
I spent a whole week trying to figure out and understand the Pressure altitude calculation, but no good results, and finally, I finally found your page after long search and I was amazed the way you explain it. you explained it in a very simple easy way. thank you so much.
I'm so grateful to you for this very clear explanation. It has indeed made me see the relevance and application of the figures gotten as the answers. It's not enough to get the answer right. The explanation and application of it is the ultimate. Thank you once again for an excellent job.
Great video.. your teaching style is so direct and was super effective for me. Hit home when you said you will kill people if you don't understand stuff like this, really kept the lights on for entire video. If you are not willing to draw picture stop watching this and wasting our time - brilliant
One of the best explanation ever! The misconception I had is that PA is somehow used to plan your actual altitude, however it is just used for performance calculations - that's it! The key point is that aircrafts are tested at 29.92" pressure and all their performance numbers are based on 29.92" pressure.
Sir first of all a big thanks to you for explaining it in so simple and straightway to the proper understanding! Would like you to continue like this ❤❤❤
I so happy in the Pressure Altitude session, Any chance to have a training session on flight planning for PPL including the wind corrections, true and magnetic heading, using the manual flight computer ?
Density is simply the looser oxygen monocular as in binding as the temperature rises such as high humidity areas in which the lift and engine cooling by air flow is affected in a way that engine running at above normal temperature and lift over the wings is impaired means I as pilot either have to change altitude to lower Density altitude if midair or possibly wait for better condition to fly .....I'm student pilot
I don't understand the concept for flying from low pressure to high and not changing the QNH, why the plane will gain height if you fly at a stay at the same set altitude and vice versa high to low. Hope this makes sense. I thought this video was brilliant. Thanks John.
24:19 Nope. ISA temperature deviation is 0.65 K for every 100m. Recalculating it to feets, gives exactly 1.9812 K / 1000 ft. In ICAO model, as far I know, they rounded it to 1.98.
Hi Junuss, just a quick question.. in your video between 33 and 34min you say ppl level must round the QNH of from 27.7 ft to 30 ft. So the question is if we do use 27.7ft and not 30ft then will the answer be wrong in a exam? I have to add, this is a great explanation
Hi Frik, for PPL exams you can use 30ft instead of 27.7ft yes. In CPL or ATP they want you to use 27.7ft. Let me know if you have any discrepancies in your questions if you use 30 instead of 27.7?
29.92 is a little easier because we know that .92 is 920' Its just a matter of moving the decimal for thousandth, hundredth, tenth. In the first example if you use 30.42-29.92 = .5 That is 500' :) Gotta make a few examples on your own and play with it for 15min and it will click
Hello sir. If you ever find this can you please comment back. I need your help with the application to an aviation school and the funding programs, I've been passing your name for almost a year now so I just thought I should give if a go and ask you for help. People around me can't help with anything because they don't know or understand half of what I'm telling them. And seeing that you helping out with PPL exam studies I take it you would understand my passion/ obsession if you might. I just don't know who or where to turn to. I really hope you get this, thank you
Simple. If the pressure altitude is lower than 29.92 (add), if its lower than 29.92 (subtract). EX: Field elevation is 5000', and the pressure altimeter is 29.82. Subtract 29.92- 29.82= .10. Multiply x 1000 = 100 feet difference in field elevation. Take 5000' field elevation and subtract 100' = 4900' is your pressure altitude. Another ex: Field elevation is 4000', pressure altimeter is 29.99. Subtract 29.99-29.92 = .07. Multiply .07 x 1000 = 70' feet difference in field elevation. Take the field elevation of 4000 + 70' = 4070 pressure altitude. No drawings needed. That's too complicated..
