Excessive Attitude
The excessive attitude format is used in the following conditions:
.
Roll is greater than 65° or less than .65°
.
Pitch is greater than 29° or less than .20°
The excessive attitude format is kept until the Roll is between ±63° and the Pitch is between 28° and .18°.
To enable the pilot to focus on the essential parameters for the excessive attitude recovery, some parameters (for example, navigation information) are removed to provide a decluttered display.
When an excessive attitude occurs, a sphere is included in the center of the FPV. The sphere has 3 positions according to Pitch angle:
.
One third illuminated when Pitch is greater than 5°
.
One half illuminated when Pitch is between ±5°
.
Two thirds illuminated when Pitch is lower than .5°.
When excessive attitude occurs, chevrons are displayed each 10° from 30° to 80° and from .20° to .80° on the pitch tape, and a roll command is displayed around the FPV. The roll command indicates the direction to roll the aircraft to return to wings level.

ENHANCED VISION SYSTEM (EVS) (IF INSTALLED)
General
The EVS consists of cockpit controls, a Head.Up Display (HUD) System, an Infrared Sensor System (ISS) and FMS CDU. The ISS consists of an Infrared Sensor Unit (ISU) and an Infrared Window (IRW).
The EVS imagery can significantly improve the pilot’s capability to detect approach lights and visual references of the runway environment that may not otherwise be visible under poor visibility conditions. The EVS also provides enhanced situational awareness during night operations.
The EVS enable descent and operation below decision altitude (DA) based on the pilot’s observation of the EVS image.
EVS Overview
The EVS is composed of two sub systems,
1. The Head.Up Display (HUD) System, which is comprised of the following units:
.
Head.Up Display Computer (HUD Computer)
.
Computer Mounting Tray
.
Optical Projector Unit (OPU)
.
Combiner Optical Unit (COU)
.
Mounting Tray (MTR)
.
Sun Visor
.
Cockpit Controls
2. The Infrared Sensor System (ISS), which is comprised of the following units:
