Piper ARCHER III - Page 223

NORMAL PROCEDURES
3. At 30 nm from the airport:
a. Verify automatic annunciation of APR ARM.
b. Note automatic dbar scaling change from ± 5.0 nm to
±1.0 nm over the next 30 seconds.
c. Update the KLN 89B altimeter baro setting as required.
d. Internally the KLN 89B will transition from en route to
terminal integrity monitoring.
4. Select NAV 4 page to fly the approach procedure.
a. If receiving radar vectors, or need to fly a procedure turn
or holding pattern, fly in OBS until inbound to the FAF.
NOTE
OBS navigation is TO-FROM (like a VOR)
without waypoint sequencing.
b. NoPT routes including DME arc’s are flown in LEG.
LEG
is mandatory from the FAF to the MAP.
NOTE
Select HDG mode for DME arc intercepts. NAV
or APR coupled DME arc intercepts can result in
excessive overshoots (aggravated by high ground
speeds and/or intercepts from inside the arc).
WARNING
Flying final outbound from an off airport vortac
on an overlay approach; beware of the DME
distance increasing on final approach, and the
GPS distance-to waypoint decreasing, and not
matching the numbers on the approach plate!
5. At or before 2 nm from the FAF inbound:
a. Select the F
AF as the active waypoint, if not
accomplished already.
b. Select LEG oper
ation.
