The double RMI needle now provides information from the KLN
900, but the NACWS display continues to indicate DME from the
selected TACAN or VOR/DME.
Brief the approach. If required determine step-down altitudes using the profile view
on the approach plate.
The GPS always displays distance to the active waypoint, which
is different than the DME distance from the navaid on the
instrument approach procedure. Pilots must exercise extreme
caution to preclude either a dangerously early or late descent on
final. DO NOT confuse GPS distance with DME.
Verify APR ARM is annunciated within 30 NM of the airfield.
The CDI scale factor will smoothly change for + 5.0NM to + 1.0
NM full deflection at this time. The CDI scale is in NM not
Press ALT to verify the altimeter setting in the KLN 900.
Select OBS mode prior to IAF if IAF/FAF are co-located OR after if IAF/FAF are not
The pilot must be familiar with the OBS/LEG function to determine
the appropriate position to select either function. Step g will be
correct for most approaches, but the pilot must ensure the correct
OBS/LEG function will be selected depending upon the IAF/FAF
At IAF perform 6 Ts.
At the end of the 2-minute outbound timing, execute the 45/180, course reversal.
Ensure the procedure turn is completed more then 3 NM from
