Foreword System Sec 1 PFD Sec 2 MFD Sec 3 Features Avoidance Hazard Sec 4 The horizon line is part of the pitch scale. Above and below the horizon line, major pitch marks and numeric labels are shown for every 10º, up to 80º. Minor pitch marks are shown for intervening 5º increments, up to 25º below and 45º above the horizon line. Between 20º below to 20º above the horizon line, minor pitch marks occur every 2.5º. Major tick marks at 30º and 60º and minor tick marks at 10º, 20º, and 45º are shown to the left and right of the zero. Angle of bank is indicated by the position of the pointer on the roll scale. The Slip/Skid Indicator is the bar beneath the roll pointer. The indicator moves with the roll pointer and moves laterally away from the pointer to indicate lateral acceleration. Slip/skid is indicated by the location of the bar relative to the pointer. One bar displacement (as shown below) is equal to one ball displacement on a traditional Slip/Skid Indicator. Roll Pointer Roll Scale Zero Slip/Skid Indicator Figure 2-10 Slip/Skid Indication The standby mechanical Attitude Indicator in your aircraft is either a Ground Pointer or a Roll Pointer configuration. The GDU 620 Attitude Indicator has been configured in either a Ground Pointer or a Roll Pointer configuration to match the configuration of your aircraft's standby Attitude Indicator. Ground/ Sky Pointer mode is configured during installation and can not be changed by the pilot. In an aircraft with an Attitude Indicator that has a Ground Pointer, the pointer above the Roll Scale shifts with the roll or bank angle of the aircraft to keep the Roll Scale Zero Pointer pointing towards the ground.
