What's the green thing on the nose of this G-V?

A handful of G's have it at my airport and they're the only ones that get in when it's all crapped up. (we get swamp fog) Aside from the freight guys that is... I've been holding short and barely seen landing lights go by so it must work pretty darn good.

GVFlyer will be along soon to scold you.

What can I say? I haven't experienced the difficulties with the EVS system that AA717Driver has...

It has saved my bacon more than once.

It's a pretty neat system.

Enhanced Vision System (EVS) capability is provided by the standard G550 Kollsman FLIR camera. The cryogenically-cooled FLIR camera operates in the 1.3 to 4.9 micron wavelength using a sensor with approximately 320 H x 240 V pixel resolution. The EVS generates a RS-170 video signal which is up-converted to an RS-343 video signal for the Flight Dynamics HUD through a scan converter.

The 1.3 micron range is in the wavelength frequency of runway lights while the longer wavelenghts penetrate clouds and fog. The wavelenght spectrum used by Gulfstream is much more capable in penetrating obscurations than the 8-12 micron band used by competitors.

Keep in mind that this is all transitional technology. There is an ongoing Gulfstream/NASA project that will culminate in the use of milimeter wave radar and synthetic vision on Gulfstream aircraft.

Aw, shucks...

One of the more difficult parts of developing this system was coming up with a raster generated FLIR image to meaningfully combine with the stroke generated HUD symbology on the combiner glass.

What you see on the HUD is green, jus' like in the movies. The EVS display which you can select on the two 14.1 inch Planeview DU-1310 MFDs (so you don't scare your co-pilot because he can't see what you're seeing in the HUD) is like a finely detailed Ansel Adams black & white photograph.

NASA had been going it alone using a Boeing 757 for synthetic vision development until one of their project pilots was invited to address the Aviation Manager's and Pilots seminar at Gulfstream Workshop in June 2001. When he saw how far along Gulfstream was on this technology he went home to Langley AFB and suggested that NASA join up with the "Big G". Since that alliance was formed the joint test article has been a GV.

GV,
Great info on the EVS, now I have to send my app. to MIT so I can understand it.

Here's an article on a pilot test of that GV, if anyone's interested.
