Instrument Approaches Flashcards
What are the three types of approaches?
precision, non-precision, and approach with vertical guidance
What are some examples of an approach with vertical guidance.
lnav/vnav, lpv, lda w/ glide slope
What is an approach clearance>
authorization to descend to the mda or da while following the approach procedure
In order to descend below the da or mda, what three things must be present?
You must have the required flight visibilty, have the runway environment in sight, and be in a position where a descent to landing can be made with a normal rate and normal manuevers
Letters at the end of an approach starting with the top of the alphabet signify what?
That the inbound course is more than 30 degrees from the runway centerline (not aligned with the runway) starts with A, then works down the alphabet for more than one approach that isn’t aligned
Letters at the end of an approach starting with the bottom of the alphabet signify what?
There are two of the same approaches to a runway. They start with Z and work there way backwards
T/F Everything inside the solid line circle is to scale and stuff outside is not to scale?
True
All navaids used in the approach are shown in what view?
Plan View, with the exception being the marker beacons which transmit on 75mgHz and will only be heard almost directly above them
Approach charts show terrain using color contours and large bodies of water using ink blots in the plan view
Treu
What four instances will you not need to make a course reversal?
- NoPT (on chart)
- Procedure Turn NA (on chart)
- Radar vectors to final
- Timed approach from hold
What view will you see that a procedure turn is not authorized?
Profile View
When is atc clearance required to make a procedure turn?
- during radar vectors
2. when cleared for timed approach from a holding fix
What are CNFs?
Computer navigation fix, can be entered as GPS waypoint, shown as a “x” on the chart, and in parantheses
Minimum safe altitudes show altitude with a 1,000 foot obstacle clearance with up to four sectors and either 25 nm or 30nm from the primary navaid, but don’t gaurentee what>
navaid reception
An altitude with a bar above and below is means it is…
a maximum altitude
An altitude without any bar above or below it signifies what?
it is a recommended altitude
Do plan view altitudes have bars?
no
What is the symbol for the final approach fix on non-precision approaches?
titled maltese cross
The ILS is divided in three parts
Guidance (localizer and glideslope), range (outer middle markers / dme), visual information (approach lights)
Where is the localizer transmitting antennea?
1,000 feet beyond the departure end of the runway
The localizer transmits on how many frequencies, and what is the range?
40 frequencies between 108.1 to 111.95, exclusive for localizers
On a localizer frequency, the three letter morse identifier is preceded by what letter?
“i”
A typical VOR has a scale of 20 degrees for a full scale right or left deflection (10 degrees deflection, five dots)
true
A localizer is how many time more precise than a VOR?
4 times
