B777 Pws
The AMM states :
PWS inhibits new windshear cautions during takeoff and
approach if both these conditions exist:
* Airspeed more than 80 knots
* Less than 400 feet radio altitude.
The use of the word "new" is baffling me a little every time I read this section.
Example 1 : If a PWS "MONITOR RADAR DISPLAY" alert is issued at say, 70 knots and the PIC elects to continue as per NNM, and then a new windshear EVENT occurs in a different location of the caution area at 90 knots, will a PWS " MONITOR RADAR DISPLAY " OCCURR ?
Example 2 : At 90 knots a windshear event occurs, will an PWS caution alert be issued ?
