thanks again, I do put the star in the FMC, but everytime I try a vnav descent something goes wrong, one time I forgot to adjust the alt hold button from cruise height, and another couple times the vnav would not change the speeds according to the fmc.
Any advice , I want to fly my trip I took a bout 6 weeks ago from Toronto to Liberia , costa Rica. I is a 5 hour flight and was in a nightmare A319( 6'3" and 275lbs and my knees were jammed into the seat). Its about a 5 hour flight. What do you do when doing long flights. I don't want to leave in case the flight goes crazy or miss top of descent.
