Press the PROC key to display the Procedures page.With “Activate?” highlighted press ENT to activatethe approach.Flying the LPV Approach1. Within 31 NM of KSLE, the 400W Series unit switchesfrom en route mode to terminal mode and the CDIscale transitions from 2.0 to 1.0 NM, full scale deflec-tion.2. As you approach the IAF (GLORR), a waypoint mes-sage (“LT TO 314° x S”) appears on the bottom of thescreen.3. As the distance (DIST) to the IAF approaches zero, themessage is replaced by a turn advisory that countsdown 10 seconds prior to the turn.4. As you approach the FAF (LOTKE), the 400W Seriesunit will begin to automatically rescale in an angularfashion. This will allow the LPV approach to be flownin an identical fashion to a standard ILS. At 2.0 NMfrom the FAF, CDI scaling is tightened from 1.0 tothe angular full scale deflection (typically the angularfull-scale deflection is 2.0°, but will be as defined forthe approach.5. Sixty seconds prior to reaching the FAF (LOTKE), theunit will check the required Horizontal Alarm Limit(HAL) and Vertical Alarm Limit (VAL) to ensure theGPS position integrity is within limits to complete theLPV precision approach. In the event the HAL or VALlimits are exceeded, the approach will be downgradedto a non-precision approach indicated by “LNAV”on the moving map, a message that the approachis downgraded (“Approach downgraded - Use LNAVminima”), and the glideslope indicator will be flagged.You may continue the approach using LNAV non-pre-cision minimums if there are LNAV minimums for thisapproach. In the rare event the GPS integrity cannotmeet the non-precision HAL limits, the unit will senda message to the pilot to abort the approach (“AbortApproach - Loss of Navigation”). The unit will revertto terminal limits to support navigation to the missedapproach when the message is acknowledged. \6. Capture the glideslope as you would an ILSglideslope.7. As you cross LOTKE, the destination sequences to theMAP (“RW31”, the runway threshold). With the needleon the external CDI (or HSI) centered, fly toward theMAP, observing the altitude minimums dictated by theapproach plate.8. When viewing the Map Page, you’ll note that the finalcourse segment is displayed in magenta (the active legLPV Approach
