Approach (2 of 2)

The position of Microbursts and Windshears are displayed using representative symbols (a shear sign and a spiral with a down arrow) on the lateral and vertical deviation graphs. The symbols are displayed in magenta.

The speed graph plots two parameters: aircraft speed (red) and a reference speed (Vref) (green).

The following data readouts and buttons are displayed in the plot toolbar area (directly below the Page Navigation Toolbar):

• Elevation
• Rwy Cond
• Gusting To
• C/L Dev
  This is the current deviation distance in dots from the active runway centre line. It is always calculated, irrespective of the aircraft's position.
• G/S Dev
  This is the current deviation distance in dots from the active runway glideslope beam centreline (or virtual glideslope if non-GS equipped). It is always calculated, irrespective of aircraft position.
• Max C/L Dev
  This is the maximum localiser deviation from the active runway. It is always calculated, irrespective of the aircraft's position.
• Max G/S Dev
  This is the maximum glideslope deviation from the active runway. It is always calculated, irrespective of the aircraft's position.
• TCH
  This is the height at which the aircraft crosses the runway threshold as it flies down the ILS glideslope.
• T/D Dist
  This is the point to point distance from the aircraft to the active runway touchdown zone. This touchdown zone is represented on most runways as 2 large white blocks either side of the runway centreline, approximately 1000ft from the runway threshold.
