IN208 Flashcards
(38 cards)
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
