IN208 Flashcards
What is the optimal approach length (FAF to MAP)?
optimal 5, max 10 nm
How many precision approaches?
2 - PAR and ILS
What does the localizer provide?
Course guidance to the runway centerline
Where is the LOC antenna located in relation to the runway?
The opposite end of the landing runway
To what distance is the LOC signal accurate and usable?
18 nm from the LOC antenna
What does the lateral deviation bar and scale on the EADI provide?
A visual depiction of your lateral location relative to the localizer
What is the width of the LOC signal?
3-6 degrees depending on the runway length
What is the normal approach angle on an ILS approach?
2.5-3.0 degrees
What does the glideslope scale and pointer show on your EADI?
Your vertical position relative to the glideslope
Where is the Outer Marker located?
At the final approach fix, or glideslope intercept point (Cyan OM indication on EADI)
Where is the Middle Marker located?
The decision altitude point on the approach (amber MM indication on the EADI)
Where is the Inner Marker located?
Between the MM and the end of the runway (white IM indication on EADI)
What would be a good idea to have when flying an approach?
A backup approach if NAVAID/AC fail ex if flying an ILS, have the LOC approach as backup
Can you be forced to transition to a LOC approach if flying the ILS approach?
Yes - you MAY NOT descend below LOC minimums if exceeding 2 dots above- (full scale deflection) OR 1 dot below glideslope (half-scale deflection)! If you are below MDA and exceeds above mentioned = go-around!
May you recapture the ILS if above LOC MDA, but has exceeded the 2 dots above/1 dot below glideslope?
Yes
When do you start your timing?
If timing is applicable, start timing when passing the FAF (for the LOC backup approach)
Do you chase the needles during an ILS approach?
No - 2 degrees pitch changes and 5 degrees target headings
How do you calculate VDP?
height of the MDA (Height Above Touchdownzone)/glideslope-angle*100
What descend rate should you use at a non-precision approach?
800-1000 fpm until MDA prior to calculated VDP
What needs to be done prior to the FAF (6 Ts)?
Time for the approach/backup approach
Turn the A/C to intercept final approach course
Throttle (PCL) set to establish descent
Twist in final approach course on EHSI
Track final approach course inbound
Talk (report FAF if instructed to by ATC and call gear down if not previously accomplished)
At what page in the GPS do you find GPS approaches?
Airport P-8 (must be loaded prior to 2 nm from the IAF, or the GPS will not go into approach mode)
Precision approaches are distinguished from nonprecision approaches by the addition of ______ information.
Glideslope
The glideslope helps maintain the proper approach angle, which is normally between ______.
2.5 and 3°
On an ILS approach with a 3° glideslope, TAS of 110 knots and a 20 knot headwind, a descent rate of about ______ fpm should be established on the VSI.
450
For many nonprecision approaches, you will need to establish a descent rate of about ______ to reach MDA prior to VDP.
800 to 1000 fpm
If the runway is not in sight when you reach VDP, you must execute a missed approach.
FALSE, continue to the MAP, and then if rwy not in sight execute a missed approach
Selecting ______ on the EHSI during a GPS approach will display the IAF(s), FAF, and MAP along with the course lines connecting them.
MAP mode
In the approach active mode, the active leg of a GPS approach is indicated on the EHSI by a ______ between waypoints.
green line
A localizer transmitter will provide course guidance and glideslope information for an approach.
FALSE, it will only provide course guidance
Which marker beacon is normally located at the FAF or glideslope intercept point?
Outer marker (OM)
In a VOR approach in which the VOR station serves as the FAF, the approach course will be ______.
outbound on the designated radial
On the GPS display, a waypoint identifier followed by a lower case “m” designates ______.
the missed approach point
An ILS is flown down to a point where you must either establish visual reference with the runway and continue to landing, or execute a missed approach. This point is called the ______.
decision altitude (DA)
On a localizer backcourse approach, you must set ______ in the EHSI.
the published front course in the course selector window
In most VOR approaches, you will use either ______ to indicate arrival at the FAF.
DME or station passage
To calculate VDP, you should divide the height of the MDA above the touchdown zone (HAT) by the desired approach angle times ______.
100
DME HOLD will not display on the EHSI when ______ is selected as the primary nav sensor.
GPS
During ILS final approach, control inputs should be minimized to prevent over controlling. You should limit pitch adjustments to 2° or less and heading corrections to ______or less.
5°
