Night Vision Systems in AH-64D Apache

The AH-64D Apache crew has different night vision systems for night operations - DCS AH-64D Apache: PNVS - Pilot Night Vision System - how to use night vision? - Systems and Sensors - DCS AH-64 Apache Guide

The AH-64D Apache crew has different night vision systems for night operations:

  1. PNVS (Pilot Night Vision System) - the main night vision system for the pilot with an infrared camera;
  2. TADS - the target acquisition system for the copilot / gunner with an infrared camera;
  3. NVG Goggles - standard night vision goggles mounted on the helmet;
  4. Flashlight - a handy flashlight in the cockpit.

PNVS - Pilot Night Vision System

AN / AAQ-11 Modernized Pilot Night Vision Sensor (M-PNVS) is the main system used by the pilot to see at night with the FLIR infrared camera. The camera is mounted on the helicopter's nose and projects its image onto pilot's IHADSS helmet display. It follows the pilot's line of sight in the following range: 20 degrees up, 45 degrees down, 90 degrees to the right and 90 degrees to the left at a speed of 120 degrees per second. Comparing to standard night vision goggles, it displays all the IHADSS flight data and infrared spectrum of "hot" targets in "Black Hot" or "White Hot" polarization. It also allows to adjust the image in terms of brightness, contrast and saturation levels. Thanks to image adjustments, the PNVS can be useful also during the day. However, the PNVS does not show tracers of Anti-Aircraft Artillery fire.

TADS - Target Acquisition Designation Sight

AN / ASQ-170 Modernized Target Acquisition Designation Sight (M-TADS) is a targeting system with an infrared FLIR camera. It is intended mainly for the copilot / gunner, who uses it in all lighting conditions for target designation, and also for terrain observation at night.

In special cases, the pilot can switch the camera view from PNVS to TADS, changing the source device - then the CPG receives the image from the PNVS. However, the TADS camera moves two times slower than the PNVS, at 60 degrees per second, so there is always a delay when looking around. The pilot cannot use TADS for target acquisition and designation - he can only observe the terrain.

Night Vision Goggles

Both crew members wear the AN / AVS-6 Aviator Night Vision Goggles - standard night vision goggles that allows to see at night - DCS AH-64D Apache: PNVS - Pilot Night Vision System - how to use night vision? - Systems and Sensors - DCS AH-64 Apache Guide

Both crew members wear the AN / AVS-6 Aviator Night Vision Goggles - standard night vision goggles that allows to see at night. The standard NVG can not be used simultaneously with the IHADSS monocle, so in this case you will not see any flight parameters or target designation. For this reason, their usefulness is severely limited and generally only advisable for a crew member who is not currently piloting the aircraft and not searching for targets, or if safe flight is possible in VFR conditions. The NVG allow crew members to see Anti-Aircraft Artillery tracer fire.
