Top of Descent calculation (PDF).

Be aware that not every airport in the world has a 3° glide slope (I´m not talking about steep descent). So check the slope´s degree on the approch charts for the runway you want to use.

Speaking of glideslopes, has the one on EGLC been fixed?


This is very helpful! Thanks!

No problem. Can you please check if the slope for LCY was changed to the original 5,5° please?

Ok, should I check using the landing aid?

Check it the way you want. I´d personally do it without the landing aid. Just tell me if the descent rate needed to stay on the slope is off -1400ft/m. Or something different to the descent rate used on 3° glide slopes.

Ok, since I have also have an Android device, I’ll check :)

Any runway?

09 and 27 have the same degree for the approach. So the one you prefer.

I can’t clearly make out the degree :/

Just tell me the descent rate needed to stay on the slope. If its of 700ish, its still of 3°, if its over 1200ish, it’s been corrected.

Would the speed of my aircraft depend on it?

So I took pics

Still a 3* :/ -700 VS, and aimed right for the threshold
