(10,000 – 20,000) x 600
VS = ----------------------------------------------
20 x 60
Complete the equation to find the correct Vertical Speed (VS) value to be
entered.
-6,000,000
VS = --------------------------------
12000
VS = -5000
The correct Vertical Speed variable is -5000 fpm.
Table 2-5 lists random TCAS Scenarios that will result in proper intruder
convergence resulting in an RA and/or TA on the TCAS display.
