Top of Descent problem

Recommended Posts

Hey everyone,

 

I am now having a problem with my T/D not showing up anywhere, and the aircraft will not descend in VNAV. It used to work just fine when I would enter my STAR before takeoff. (I was being lazy.) What happens now is I will set up the flight plan with a SID and then program the FMC to fly direct to the destination airport. When about 400 nm out or so, I will enter a STAR. LNAV will disengage due to a discontinuity, and I will go into the LEGS page and correct any discontinuity. However even after that, the PROG page will only show E/D distance, and never show T/D. VNAV will also not show the T/D, and T/D never shows up on the EFIS. Also, after entering the STAR, the descent profile indicator will show up on the EFIS. (This never shows up until the descent begins normally.) Doh! Any advice? Thanks.

apart from the SID; the STAR and arrival airport you need an entry in the RTE section....just one waypoint will do, even if not accurate

Pschlute,

 

Thanks for the prompt reply. If im flying to an airport without a STAR but rather only a transition, what should I enter into the RTE page?
