- What is a difference between an SDF and LDA facility?
The SDF course width is either 6° or 12° while the LDA course width is approximately 5°
The SDF course has no glide scope guidance while the LDA does
The SDF has no marker beacons while LDA has at least an OM.
The SDF course width is either 6° or 12° while the LDA course width is approximately 5°

- What is the difference between a localizer type directional aid (LDA) and the ILS localizer?
The LDA is not aligned with the runway
The LDA uses a course width of 6° or 12° while, an ILS uses 5°
The LDA signal is generated from a VOR type facility and has no glide scope
The LDA is not aligned with the runway

- Which substitution is permitted when an ILS component is in operative
A compass locator or precision radar may be substituted for the ILS outer or middle marker
ADF or VOR bearings which cross either the outer or middle marker sites may be substituted for these markers
DME when located at the localizer antenna site should be substituted for the outer or middle marker
A compass locator or precision radar may be substituted for the ILS outer or middle marker

- Which of these facilities may be substituted for an MM during an ILS IAP

A VOR/DME fix

- Which of the following conditions is required before “timeed approaches from a holding fix” may be conducted
If more than one missed approach procedure is available only one may require a course reversal
If more than one missed approach procedure is available Nantmeal require a course reversal
Direct communication between a pilot in the tower must be established prior to beginning the approach
If more than one missed approach procedure is available none may require a course reversal
Page 209
- If only one missed approach procedure is available which of the following conditions is required when conducting time approaches from a holding fix
The pilot must contact the airport control tower prior to departing the holding fix inbound
The reported ceiling and visibility minimums must be equal to or greater then the highest prescribed circling minimums for the IAP
The reported ceiling and visibility minimums must be equal to or greater than the highest prescribed straight in MDA minimums for the IAP
The reported ceiling and visibility minimums must equal to or greater than the highest prescribed circling minimums for the IAP

- When making a time to approach from a holding fix at the outer marker the pilot should adjust the
Holding pattern to start the procedure turn at the assigned time
Airspeed at the final approach fix in order to arrive at the missed approach point at the assigned time
Holding pattern to leave the final approach fix inbound at the assigned time.
Holding pattern to leave the final approach fix inbound at the assigned time

- Under which condition does ATC issue a STAR
To all pilots wherever STAR’s are available
Only if the pilot requestIna STAR in the remarks section of the flight plan
When ATC deems it appropriate unless the pilot request “no STAR”
When ATC deems it appropriate unless the pilot request no STAR
