Cockpits and Systems

Unlike the AH-64A, the AH-64D replaces the analog cockpit displays and instrumentation with a number of digital multipurpose displays. These displays allow a crew to 'reconfigure' on the fly for a particular situation: combat, navigation, etc. and cull unnecessary information for a particular regime. The primary displays are the MPDs or Multi-Purpose Displays. These occupy the central area of the pilot's cockpit and the left and right edges of the gunner's cockpit. These are followed by the Up Front Display at the top of the dash. The pilot has analog standby instruments on the right side of the dash for emergency use. The various instrumentation and their position in each cockpit is described below.

IHADSS

IHADSS or Integrated Helmet And Display Sighting System is a helmet mounted display (HMD) that displays information on a single CRT monocle over the right eye. The helmet uses IR transmitters and sensors to track the pilot's head direction and position. The CRT is monochrome and can display visual data from the TADS or PNVS sensors in addition to symbology. There are four symbology modes available: Transition (default), Cruise, Hover, and Bob-up. Each mode displays different information for different flight parameters.
