thank you glider12000 , moving further another question :-) to the picture attached
those two circles based on CYQX and BIKF showing you - what ? they are also marked ex. CYQX/740/120
ETOPS entry and exit points you mentioned ex.ETP-1 EET 2:05 ? what does that mean
There are also time CYQX 18:16/20:42 and BIKF 18:59/21:22 also question what are those times
Thank you for any answers I know that everything is on internet but sometimes having an quick answer for 2-3 specific questions bright your mind enough to understand the topic than reading tons of theory lectures
