SU 6 Holding and Instrument Approaches Flashcards
What conditions are necessary before ATC can authorize a visual approach?
You must have the airport in sight or a preceding aircraft to be followed, and be able to proceed to the aircraft in VFR conditions
What are the main differences between a visual approach and a contact approach?
The pilot must request a contact approach; the pilot may be assigned a visual approach and higher weather minimums must exist
A contact approach is an approach procedure that may be used
in lieu of conducting a SIAP
You arrive at your destination airport on an IFR flight plan. Which is a prerequisite condition for the performance of a contact approach?
Clear of clouds and at least 1 SM flight visibility
Flying clear of clouds on an instrument flight plan, what are the requirements for a contact approach to an airport that has an approved IAP?
The pilot must request the approach, have at least 1 mile visibility, and be reasonably sure of remaining clear of clouds
When is radar service terminated during a visual approach?
Automatically when ATC instructs the pilot to contact the tower
When may you obtain a contact approach?
ATC will assign a contact approach only upon request if the reported visibility is at least
What are the main differences between the SDF and the localizer of an ILS?
The SDF course may not be aligned with the runway and the course may be wider
How wide is an SDF course?
Either 6 degrees or 12 degrees
A precision Runway Monitor (PRM) approach requires
simultaneously monitoring two frequencies
Precision Runway Monitoring (PRM) is
a RADAR system for monitoring approaches to closely spaced parallel runways
If the RVR equipment is inoperative for an IAP that requires a visibility of 2,400 RVR, how should the pilot expect the visibility requirement to be reported in lieu of the published RVR?
As a ground visibility of 1/2 SM
If the RVR is not reported, what meteorological value should you substitute for 2400 RVR?
A ground visibility of 1/2 SM
(Refer to Figure 178 on page 233 and Legend 21 below.) You have been cleared for the Straight-in Localizer approach for runway 13L at DAL. Prior to reaching the final approach fix. ATC advises you the RVR is not available and that the visibility is 1/2SM You may
convert the RVR to statue miles and continue the approach
What does the Runway Visual Range (RVR) value, depicted on certain straight-in IAP Charts, represent?
The horizontal distance a pilot should see when looking down the runway from a moving aircraft
The RVR minimums for takeoff or landing are published in an IAP, but RVR is inoperative and cannot be reported for the runway at the time. Which of the following would apply?
RVR minimums which are specified in the procedure should be converted and applied as ground visibility
RVR minimums for landing are prescribed in an IAP, but RVR is inoperative and cannot be reported for the intended runway at the time. Which of the following would be an operational consideration
RVR minimums which are specified in the procedures should be converted and applied as ground visibility
(Refer to Figure 187 on page 235.) When conducting a missed approach from the RNAV (GPS) X RWY 28L approach at PDX, what is the minimum safe altitude (MSA while maneuvering?
5,800 feet MSL
(refer to Figure 233 below.) The missed approach point for the DUC RNAV (GPS) RWY 17 (LNAV/VNAV) procedure is
1,903 MSL
(Refer to Figure 249 below.) At what point would a pilot execute the missed approach for the LNAV approach at LBF?
RW 30 waypoint for the LNAV
If an early missed approach is initiated before reaching the MAP, the following procedure should be used unless otherwise cleared by ATC
Proceed to the missed approach point at or above the MDA or DH before executing a turning maneuver
If the pilot loses visual reference while circling to land from an instrument approach and ATC radar service is not available, the missed approach action should be to
make a climbing turn toward the landing runway and continue the turn until established on the missed approach course
Which of the following statements is true regarding parallel ILS approaches
Parallel ILS approaches provide aircraft minimum of 1 1/2 miles radar separation between successive aircraft on the adjacent localizer course
If an ILS components are operating and the required visual references are not established, the missed approach should be initiated upon
arrival at the DH on the glide slope
If during an ILS approach in IFR conditions, the approach lights are not visible upon arrival at the DH, the pilot is
required to immediately execute the missed approach procedure
How does pilot determine if DME is available on an ILS/LOC
IAP indicate DME/TACAN channel in LOC frequency box
(Refer to Figure 61 below.) Determine your position relative to the glide slop and localizer course
Above the glide slope and right of the localizer course
(Refer to Figure 140 below, and Figure 139 on page 241.) Which displacement from the localizer and glideslope at the 1.9 NM is indicated?
710 feet to the right of the localizer centerline and 140 feet above the glideslope
(Refer to figure 139 on page 241 and figure 141 on page 241.) Which displacement from the localizer centerline and glideslope at the 1,300-foot point from the runway is indicated?
21 feet above the glideslope and approximately 320 feet to the left of the runway centerline
(Refer to figure 139 on page 241 and figure 141 on page 241.) Which displacement from the localizer and glideslope at the outer marker is indicated?
1,550 feet to the left of the localizer centerline and 210 feet below the glideslope
(Refer to Figures 140, 141, and 142 below.) Which displacement from the localizer centerline and glideslope indicates you are high and to the left of ILS course?
Figure 141
(Refer to Figures 140, 141, and 142 below.) Which displacement from the localizer centerline and glide slope indicates you are low and to the left of the ILS course?
Figure 142
(Refer to Figures 140, 141, and 142 below.) Which displacement from the localizer centerline and glideslope indicates you are high and to the fight of the ILS course?
Figure 140
Which pilot action is appropriate if more than one component of an ILS is unusable
Use the highest minimum required by any single component that is unusable
Which substitution is appropriate during an ILS approach?
LOC minimums should be substituted for ILS minimums whenever the glide slope becomes inoperative
A pilot is making an ILS approach and is past the OM to a runway which has a VASI. What action is appropriate if an electronic glide slope malfunction occurs and the pilot has the VASI in sight?
The pilot may continue the approach and use the VASI glide slope in place of the electronic glide slope
Immediately after passing the final approach in IFR conditions, the glide slope warning flag appears. The pilot is
permitted to continue the approach and descend to the localizer MDA
When installed with the ILS and specified in the approach procedures, DME may be used
in lieu of the OM
When passing through an abrupt wind shear which involves a shift from a tailwind to a headwind, what power management would normally be required to maintain a constant indicated airspeed and ILS glide slope?
Lower than normal power initially, followed by a further decrease as the wind shear is encountered, then an increase
The rate of descent on the glide slope depends on
ground speed
The rate of descent required to stay on the ILS glide slope
must be decreased if the ground speed is decreased
