Your voice is so perfect and good that even some hard topics can be easily understood and learned from your videos!!! ❤️ Thank u so much for your great videos, Waiting for more such knowledgeable videos in the Future👍👍
@@JxJAVIATION there's a difference actually, radar altimeter uses the echo principle, just like a normal radar. Radio altimeter uses FMCW, continuous wave, the principle is that rate of change of frequency is constant while flying at a constant height. Transmitted Frequency is varied between 4.2-4.4 Ghz and the reflected signal is at a different frequency than the transmitted one, and since the rate of change of frequency is constant, the difference is proportional to the time taken. Change of freq= Rate of change of freq X time taken. The frequency difference is measured and the time obtained is registered on the indicator as height. Just sharing, as a well wisher, do let me know if this doesn't sound right

Thank you so much! This is the best Comment/Compliment I have received. Made my day!
Amazing video. Love ❤️ u. Make more videos please
Thank You! I will
Many thanks, I do relly like you explaination.
Glad to hear that! Keep Watching! Cheers!!
very informative. thanks
Glad it was helpful!
Thanks indeed.
Very welcome
Very nice
Thank you and Welcome! Do check out my other videos as well!
Amazinggg
Thank you! Check out my other videos as well!
love your video 3mins full of knowledge , just quick question , why the distance= 2xheight ?
Thank you! 2xHeight because the radio waves travel towards the ground (1xH) and are reflected towards the aircraft (another H)!
Good job ❤️
Thanks :)
Niceeee
Thanks 🤗
@@JxJAVIATION i have to watch all your Videos soon. Many Thanks for the great content 👍👍👍
@@drseven1275 Please Do Watch and Share!
Very nice video and informative. What is 1410 is showing in the RA system, which is circled?
Its the RA height information from the RA computer
Please would you mind to upload a video of METARS ?
I will note it!
plus maximum distance is 2500ft
Oh yes! Thank You!
Isn't what you explained a Radar altimeter and not a radio altimeter?
I think we are referring to the same system!

error of operation in radio altimeter?
There could be a system fault or obstructions to the radio waves causing error in the readings.
