The description of the 5 May 05 crash of an Apache described "during a training mission with a form of NVGs called forward-looking infrared." NVGs are Night Vision Goggles. They are worn in front of the eyes (lightweight) and magnify available starlight, moonlight, etc. Forward-Looking Infrared (FLIR) is a night vision device that is relatively large and works by discriminating the difference in temperature (IR energy) between objects. FLIR does not require any light. FLIR is only limited by its own "minimum resolvable temperature" and the display device used. Apache helicopters have two FLIR turrets mounted on the nose of the helicopter. The top one is the Pilot's Night Vision System (PNVS) used normally by the backseat pilot to fly the aircraft. The Target Acquisition and Targeting System (TADS) includes a FLIR with magnification capability used normally by the copilot-gunner to engage targets or to fly the aircraft. Both FLIRs move independant of one another and when used for pilotage, they are slaved to the motion of the pilots' helmets and the FLIR video is displayed on a combiner lens in front of their right eye. Collectively, NVGs and FLIR systems are refered to as NVDs (Night Vision Devices). While a FLIR system alone is sometimes refered to as an NVS (Night Vision System). Currently, however, there is no such thing as a FLIR "goggle." More info available at : www.hometown.aol.com/ah64info

Paul,
I recall the TADS being the Target Acquisition and Designation System (or Sight). Has the name changed for the Longbow? I was a Apache IP/IE in the 90's, but left the Army in 98.

As usual the IP is correct.

Just a clarification - The acft crashed during daylight/twilight hours. NOT a night mission, NOT on system, NOT on goggles, in VFR-albeit hazy weather.
