Eventually you are going to have to know things like when the GPS
switches
from "ARMED" to "APPROACH" modes and what the channel number is for on
WAAS
approaches.

What's the channel number for on WAAS approaches? Thanks.

From AIM 1-1-20 (d) "Flying Procedures With WAAS"

6. A new method has been added for selecting the final approach segment of
an instrument approach. Along with the current method used by most receivers
using menus where the pilot selects the airport, the runway, the specific
approach procedure and finally the IAF, there is also a channel number
selection method. The pilot enters a unique 5-digit number provided on the
approach chart, and the receiver recalls the matching final approach segment
from the aircraft database. A list of information including the available
IAFs is displayed and the pilot selects the appropriate IAF. The pilot
should confirm that the correct final approach segment was loaded by cross
checking the Approach ID, which is also provided on the approach chart.
