All big EFIS planes that have an inertial reference system seem to have this kind of wind vector, the key is breakdown into two components that are parallel and perpendicular to the plane's trajectory: crosswind and head-/tailwind components.

I recall that in the Boeing FMC's last PROG page. (737, 747 and 777, and I imagine others as well) there is a breakdown for the head-/tailwind and crosswind components.



I haven't seen it in the Airbus MCDU, but like Boeings 'buses have a wind vector on the ND as well, as do the F100/F70s.

The MD-11 is the only plane I've seen which has a gauge similar to what the guy at the top describes.

In the upper left corner of the ND you can see it, two perpendicular arrows with the respective indications for the values in knots below the TAS/GS readouts. As you can see it displays a 4-knot headwind.
