Figure 3-12. Inserting published instrument procedures into a flight route. Check the Waypoints Check the Distances On the flight planning page, compare the sequence of  waypoints with that prescribed by his or her clearance. Are  any waypoints missing? Did you mistakenly include any extra  waypoints in the route? Did you misspell any waypoints?  Did the computer mistakenly include any extra waypoints  in the route? On the flight planning page, you can see that the computer  has calculated the distances between the waypoints in the  route. These distances can be checked against the en route  charts. A common error is to misspell the name of a waypoint  and, thus, mistakenly enter a waypoint not appropriate to  the planned route (e.g., KHEE versus KHEF). Checking the  waypoint distances for unusual numbers is a good way to  spot these errors. 3-10 C RING MSG FPL PROC NRST OBS GPS COM  C V PWR VOL/ SQ PUSH VOL/ ID PUSH C RING MSG FPL PROC NRST OBS GPS COM  C V PWR VOL/ SQ PUSH VOL/ ID PUSH C RING MSG FPL PROC NRST OBS GPS COM  C V PWR VOL/ SQ PUSH VOL/ ID PUSH C RING MSG FPL PROC NRST OBS GPS COM  C V PWR VOL/ SQ PUSH VOL/ ID PUSH C RING MSG FPL PROC NRST OBS GPS COM  C V PWR VOL/ SQ PUSH VOL/ ID PUSH PROC PROCEDURES VLOC 116.00 114.10 COM 123. 850 125.100 Activate Vector-To-Final?
