Approach Procedures
Operations
approach, it is necessary to add one so that the equipment can do these
TSO required tasks. This equipment-required FAF is called a sensor
FAF and it is always located on the final approach course prior to the
MAP. If there is already a named waypoint which can be used, it
becomes the sensor FAF. If not, a sensor FAF waypoint is created. In
the Wenatchee approach example, this waypoint is named FF285.
FF285 is the sensor FAF and the inbound course for the approach is
285°. FF285 appears on the Jeppesen approach procedure chart, but
not on the National Ocean Service (NOS) approach procedure chart
for this approach.
This is especially important to understand when a procedure turn or
course reversal is required. If you are inbound from the CASHS
intersection, a procedure turn is required. You must execute this
procedure turn on your Apollo NMS relative to FF285, the TSO C129a
FAF, not relative to the EAT VOR as depicted on the NOS chart as it is
necessary to cross this sensor FAF waypoint inbound in order for the
Apollo NMS to go approach active (approach active annunciator lit)
and allow you to complete the approach. This is clearly depicted on the
Jeppesen approach procedure chart.
