i was searching for another thing and accidentally i found the track elevation (the one that i was supposed to land), but now i searched again and couldn't find.where can i see the landind altitude (or track elevation)?

You can check the charts of the ariport OR you can go to the legs page, and check your altitude at the runway threshold point (that point is usually called RWxy) and subtract 50ft from that, because your height above the threshold is approximately 50ft
