Missing something obvious with VNAV

[brammy]

Hi all,

In my test flight yesterday I noticed the TOD never showed up, and the flight plan page didn't have the constraints.

I've tried looking in the manual for the step I missed but can't figure it out.

The FMS performance computations (including the T/C and T/D points) are reliant on all mandatory fields being completed on the INIT A and INIT B pages, plus a valid flight plan being entered on the F-PLN pages.

On your next flight, it'll be worth double-checking that all fields on those pages which have square boxes have data entered, and that should feed the FMS all the data it needs for the T/C and T/D points.

Hope that helps.
