Departure, Arrival,Approach Procedures Flashcards
What is STAR’s and what is the purpose of it?
- Standard Terminal Arrival Routes
- It’s an ATC coded IFR route for certain airports to simplify clearance delivery
How do you know if the localizer is a front course localizer?
- It will have a shaded right side on the localizer symbol on the chart
What would you use UNICOM frequency for?
To find out from the FBO where to get fuel, parking, taxi etc.
What gives you lateral and vertical guidance on a precision approach?
Lateral: Localizer
Vertical: Glideslope
When would you decide to go missed on an ILS precision approach?
- Decide to go missed at DA
- You can descend below decision altitude as you execute missed approach
When would you decide to go missed on a localizer with no vertical guidance, non-precision approach?
- Decide to go missed at any time
- You cannot descend below MDA
- Must hold MDA until you reach missed approach point MAP
What are the four legs of a hold?
- An inbound leg towards the holding fix
- An outbound leg
- 2 turns
The FARs require that all turns in the hold use the smallest bank angle out of these three options:
- 3° per second (standard rate turn)
- 30° bank angle
- 25° bank angle when using a flight director system for landing
For published holding procedures, ATC only needs to include the following in the clearance:
- The holding fix
- The direction of the holding pattern relative to the fix (N, S, E, W)
- EFC Time (Expected further clearance)
For non-published holds, ATC must include:
- The direction of the holding pattern from the fix
- The holding fix
- The radial, course, airway, route on which to hold
- The leg length in miles (if DME or RNAV) or minutes otherwise
- The direction of turns, if left, otherwise right turns are standard
- EFC time
Holding speed restriction 6,000’ and below?
200 kts
Holding speed 6,001’ - 14,000’?
230 KTS
Holding speed 14,001’ and above?
265 KTS
Holding speeds for Air Force Fields?
310 KTS
Holding speed for Navy fields?
230 KTS
Unless published or instructed otherwise by ATC, the inbound leg timing is:
- 1 minute below 14,000’ MSL
and - 1.5 minutes at 14,001’ MSL and above
The inbound timing begins when:
Established wings-level on the inbound turn and ends at the fix
If you’re inbound leg is short or longer than 1 minute, how would you adjust to make it 1 minute?
- You would adjust the outbound leg to accommodate the off timing of the inbound leg
- The outbound leg begins when the aircraft passes abeam or over the holding fix
What may be given in place of timed turns?
- Leg lengths may be given instead of time
How do you compensate for wind during holdings?
- Find the correction angle required to stay on the inbound course
- Multiply that by 3 for the outbound leg
- Do not compensate for wind during turns, as the massive correction on the outbound leg is to compensate for the standard rate to turn back on course
What are the 5 T’s for remembering the actions over and abeam the holding fix?
- Turn: Turn the aircraft to follow the desired entry technique
- Time: Note the time over the holding fix. Start the timer (when turning outbound) when wings are level or when abeam the fix
- Twist: Set the OBS to inbound course
- Throttle: Adjust power to maintain holding speed
- Talk: Advise ATC of time & altitude at which the aircraft reached the holding fix
(6th “T” think ahead)
What are questions to ask yourself when it comes to holds?
- How long can I stay in the hold w/ the available fuel?
- What is my alternate plan if ATC does not release me by that time?
- What is the current weather and availability of other airports in the area if I have to divert?
What must you do when you tune into the localizer before using it for guidance?
- IDENT the localizer, listening for the morse code to verify the localizer is working
The localizer provides_________ when on an ILS approach.
Lateral guidance
How are localizer’s and VOR’s different from each other?
- Localizer only supports a single specific direction
- VOR facilitate navigation on any bearing around the station from 0º to 360º
- Turning the OBS knob does not affect the CDI displacement (still a good idea to set the inbound course of the published approach
Localizer frequencies only use these frequencies:
Odd tenths (i.e. 108.1, 110.7 MHz)
Localizer width range between what degrees?
- 3º to 6º
- Typically 5º (2.5º full deflection to each side)
- Depends on the runway length to ensure 700’ course width at the runway threshold
How high does the coverage of the localizer go?
- Covers altitude up to 4,500’
- 35º to each side of the centerline up to 10NM
- 10º to each side of the centerline up to 18 NM
Describe how the localizer works.
- The localizer antenna modulates 2 signals on the single VHF. One at 90Hz and the other at 150Hz
- In a narrow pattern, these signals are emitted to each side, left and right, of the localizer centerline
- The aircraft receives the 90Hz signal more intensely when it is further to the left of the signal, and receives the 150Hz more when to the right of the center of the signal
- The CDI displays which direction to move in order to center the CDI
What indicates position for FAF intercept, and how far out can it be picked up?
-(OM) Outer Marker beacon can be picked up 4-7 miles out from runway threshold
- Outer Marker indicates the position for glide slope intercept
- Shown as blue
What indicates where the Glide Slope meets DH?
- (MM) Middle Marker beacon indicates where glide slope meets DH
- Approximately 3,500’ from runway
- Usually 200’ above touchdown zone elevation
How many ILS categories are there, and what are they called?
- There are 5 ILS categories
- CAT I
- CAT II
- CAT IIIa
- CAT IIIb
- CAT IIIc
What is minimum visibility and DH of a CAT I ILS?
Vis: 2,400’ or 1,800’
DH: 200’ AGL?
What is minimum visibility and DH of a CAT II ILS?
Vis: 1,200’
DH: 100’
