How to - Change Weather Radar (WXR) / Terrain Awareness and Warning System (TAWS) Modes via the Surveillance (SURV) MFD Page

SYSTEM OVERVIEW

The Surveillance (SURV) system consists of the following system that perform surveillance functions:

• Traffic Collision Avoidance System (TCAS)
• Automatic Dependent Surveillance - Broadcast - Traffic (ADS-B Traffic)
• Transponder (XPDR)
• Weather Radar (WXR) system
• Terrain Awareness and Warning System (TAWS)

This FAQ will cover the WXR and TAWS features of the SURV system. For TCAS, ADS-B Traffic and XPDR systems, see: 

SURV - CONTROLS AND INDICATORS

The SURV system functions can be controlled via

1. SURV Panel on the Pedestal
2. SURV Page on the on the MFD

1. SURV Panel on the Pedestal

For the purpose of this guide, we are only interested in the WXR SYSTEMS and G/S Mode pushbutton of this panel.

• G/S Mode Pushbutton: Toggles the GPWS (Mode 5) function which monitors for excessive descent below the glide slope. A white OFF light is on when this is switched off.
• WXR SYS1 / 2 Pushbuttons: Toggles the primary SURV system responsible for interpreting Weather Radar Antennae data.

• WXR/PWS toggle: Toggles the Weather Radar (WXR) and Predictive Windshear System (PWS) between AUTO and OFF. When set to OFF, the respective system display, warnings and audio alerts are disabled.
• TURB toggle: Toggles the Turbulence Detection (TURB) system between AUTO and OFF.
• MODE toggle:  Toggles the radar function between Weather display (WX) and ground mapping (MAP).*
• GAIN toggle: Toggles between AUTO or Manual (MAN) gain control for the WXR.*
• ELEVN/TILT Option List: Toggles between AUTO or Manual (MAN) control of elevation (ELEVN) mode or WXR tilt (TILT)*
  * = Not available in sim currently due to limitations of the sim weather API.
