Exercise 6.5: Instrument Approaches 1. When first selecting an approach, what is the default option that appears when the PROC Key is pressed? "Select Approach" is the first option displayed when the PROC Key is pressed. 2. What is the difference in how the HSI presents data between selecting Vectors-to-Final or an Initial Approach Fix during an instrument approach? When Vectors-to-Final is selected, the HSI sets the inbound approach course automatically and it can be intercepted in the same way it would when getting vectors to a ground-based NAVAID. When the full approach is selected, the system provides guidance to the Initial Approach Fix. 3. Describe the CDI scaling that occurs when flying a GPS approach, according to the AIM. • When transitioning to within 30 nm of the destination, the CDI gradually scales down from 2.0 nm to 1.0 nm full-scale deflection. • When within 2 nm of the FAF, the CDI gradually scales down to 0.3 nm (556 meter) full-scale deflection for LNAV and LNAV/VNAV approach mode, to 40 meters for LPV. • Also adds vertical integrity monitoring, for LNAV/VNAV and LPV approaches vertical error to 50 meters. • On the missed approach, the scaling changes to 0.3 nm when the first leg of the missed approach is a track to fix leg aligned within 3° of the inbound course until the turn initiation point for the first waypoint in the missed approach procedure, at which time it will change to 1.0 nm sensitivity. 4. When navigating using the GPS, if an ILS, LOC, or VOR approach is selected, where is the frequency for the primary approach navigational aid automatically placed? The primary approach NAVAID frequency is placed in the active frequency field of NAV1. 5. When flying an ILS approach, where do the Glideslope Indicator and Marker Beacon Annunciation appear on the PFD? The Glideslope Indicator appears to the left of the Altimeter and the Marker Beacon Annunciation appears above the Glideslope Indicator. 6. Can GPS be used to fly a VOR approach? Yes, but only if the title of the approach plate is "VOR or GPS". 7. Does GPS provide guidance data to the autopilot to allow it to fly a coupled holding pattern? Yes, GPS guidance is provided to the autopilot for flying holding patterns. 8. Can GPS be used in lieu of DME when flying a DME arc associated with a VOR, LOC, or ILS approach procedure? Yes, provided the arc procedure is depicted in the database. 24 GIFD Pilot's Training Guide 190-00368-05 Rev. B
