Latonlite,
With no WR selected on there is no time delay....On take off once either throttle goes above 53 degrees the PWS detection is ON. I think you may be confused with the 12 second thing. If WR is not selected on before takeoff then all sweeps of the dish are detecting WS. If WR is selected on before takeoff see below:
Takeoff WR selected on with throttles >53 degrees:
Sweep 1 left to right: Capt WR for the first 3 second period.
Sweep 2 right to left: Both PWS for the next 3 second period.
Sweep 3 left to right: F/O WR for the next 3 second period.
Sweep 4 right to left: Both PWS for the next 3 second period.
And then so on. The most time delay you could have is 3 seconds.
As for the birds..................
