runway. Assigned altitudes must be maintained until established on a published
segment of the approach. Required altitudes at waypoints outside the FAWP or
stepdown fixes must also be considered.
14.2.3.2.5 Flying point to point on the approach does not assure compliance with
the published procedure. The proper RAIM sensitivity will not be available and
the CDI sensitivity will not automatically change to +0.3 NM. Manually setting
CDI sensitivity does not automatically change the RAIM sensitivity on some
receivers.
14.2.3.2.6. Loss of final approach guidance on an RNAV or GPS approach
procedure is annunciated in a variety of ways depending on your particular
avionics installation. In some aircraft the CDI will center when the “GPS
Integrity” light illuminates and can give the illusion that you are on course.
Insure you are thoroughly familiar with failure annunciations for your aircraft and
discontinue the approach immediately if course guidance is suspect.
14.2.3.3. Final Approach
14.2.3.3.1. Descent to MDA or DA. Do not descend to MDA, DA, or step down
fix altitude until passing the FAF.
14.2.3.3.2. Vertical Navigation. Unless circling from the approach, VNAV
guidance should be followed if provided by aircraft avionics and certified for
use IAW AFI 11-202 Volume 3, General Flight Rules. VNAV guidance may be
used to LNAV minimums; however, the aircraft must level off prior to MDA if
the runway environment is not in sight. Due to the temperature and pressure
altitude effects, USAF crews shall not use VNAV guidance below published
MDA or DA.
14.2.3.3.3. Step Down Fixes. USAF pilots must comply with all stepdown fixes
depicted on the IAP. VNAV guidance should provide clearance from all step
down fix altitudes, however, crews must monitor altitude at all step down fixes to
ensure compliance.
14.2.3.3.4. Runway Environment. Do not descend below MDA/DA unless
sufficient visual reference with the runway environment has been established and
the aircraft is in position to execute a safe landing.
14.2.3.3.4.1. Missed Approach. To execute a missed approach, activate the
missed approach after crossing the MAWP. GPS missed approach
procedures require pilot action to sequence from the MAWP to the missed
approach procedure. If the missed approach is not activated, the GPS receiver
will display an extension of the inbound final approach course, and displayed
distance will increase from the MAWP. Do not activate the missed approach
prior to the MAWP. Once the missed approach is activated, CDI sensitivity is
set to 1NM. Missed approach routings in which the first track is via a course
rather than direct to the next waypoint require additional action from the pilot
to set the course (consult your flight manual). Do not turn off of the final
approach course prior to the MAWP.
