Airbus THALES BOX. Loss of VDEV when in HDG mode
Hi
I have noticed that in models with the THALES FMEGS, when we are in HDG because we are being vectored, the VDEV in the PFD and the PROG page dissapear (not immediately but at a few miles off the green line).
Perhaps it is a glitch but I haven't seen it in the looooong list of those "specificities". So I suspect it is like that per design, probably induced by some *#%&* lawyer.
Normally I don't need the VDEV, as I can calculate pretty accurately how many miles I need to land, but I like to compare with the FMS, and if there is a discrepancy I verify what is going on. Sometimes happens that I'm not considering some AT constraint, for instance.
Also is good to have it when my brain is not performing at its optimum. To put it short: I want to have the bl00dy VDEV. Why does THALES deny me what HONEYWELL has been giving me so long?
