AMC1 ACNS.E.TAWS.080 Pop-up mode

ED Decision 2013/031/R

For dual displays installations, when an automatic pop-up mode is provided, the pop-up function should be inhibited if terrain is already presented on at least one display.

If TAWS and the Predictive Windshear System share the same display and an automatic pop-up function is employed, the display priorities indicated in Table 4 are recommended:

 

Priority

Description

Highest

Terrain Awareness Warning

Predictive Windshear Warning

Terrain Awareness Caution

Predictive Windshear Caution

Normal Terrain Display

Lowest

Weather Radar Display

                                                         TABLE 4: Alert display priorities

 

If the TAWS system provides alerting for obstacle threats, the priority for warning and cautions should be the same as those for terrain.
