Gulfstream and Honeywell were first to develop SVS for a transport category jet, and Garmin first to bring the technology to piston airplanes, turboprops and light jets. And to me, SVS is the game changer. The debate is over. With SVS and its almost magical ability to orient a pilot to his surroundings and the destination runway, as well as traffic tracked by the traffic warning system, IFR flying is so very close to VFR. The flight path guidance with the terrain around you moving at the appropriate speed gives the same clues to attitude, airspeed and altitude one gets when flying in the clear. Yes, you still need to read the numbers, or observe the bugs you set, to stay on the assigned altitude or heading, but the orientation is delivered at a glance. With SVS a new instrument pilot will need to learn IFR procedures, but actual control of the airplane in the clouds or under the hood should be a snap compared to any previous display.
