Hello,
I apologize if this has been answered previously, but I could not locate a similar issue here. On p29 of Tutorial #2:
Next we’ll enter the enroute portion of the route.
Press LSK 6R to go to back to the RTE page 1.
Press NEXT PAGE to get to RTE page 2, where we enter
airways.
Enter the first airway, UZ738 into the VIA column at LSK 2L.
My FMC states INVALID ENTRY each time I try the step in the last bullet.
Can someone please let me know what I need to do?
Thanks in advance.
