Question 1

Wind Display Description

Accessing the Winds Points Table

Answer 1

The CAATS Winds Display function provides the controller with the ability to view the forecast winds for any location on the CSiT display at several altitudes.
The altitudes available for display in CSiT are from 5000 feet to FL510. Up to 24 different altitudes are available for display and are adaptable on a consolidation basis.

To access to the CAATS winds table:
* click-and-hold the MB3 button on any unoccupied area of the radar screen.
* select ‘Winds’ from the popup menu.

Question 2

TOP OF DESCENT CALCULATION

Answer 2

Use three times the aircraft altitude plus or minus 1/3 of the wind to determine an approximate TOD point. (e.g., Aircraft at FL400 with a 90knot tailwind would begin descent at (FL)40 * 3 = 120 + 30(1/3 of wind) = 150 NMS from destination.
