Flashcards in 240/AIM Deck (36):
What does the L stand for in the L class VOR?
What does the H stand for in the H class VOR?
How many degrees off course are you when you have full scale deflection on a VOR approach?
At least 10 degrees
How many degrees off course are you when you have full scale deflection on an ILS approach?
At least 2.5 degrees
What are the classes of NDB's and what distances are associated with them?
L = 15nm
MH = 25nm
H = 50nm
HH = 75nm
What does category A,B,C etc mean on an approach?
-Its determined by the aircraft speed, and usually changes the weather minimums.
If I am 60nm from a VOR how wide is each radial?
What are the speeds associated with category's A,B,C,etc?
A: 1-90 kts
B: 91-120 kts
C: 121-140 kts
D: 141-165 kts
E: 166 kts+
Are category speeds determined by airspeed or ground speed?
If circling to land using category A approach minimums how large is the obstacle clearance area?
When do you start a turn on a departure procedure?
400 feet above departure end of the runway
What is a precision approach?
A standard instrument approach procedure that has a glideslope/glidepath.
What is an example of a precision approach?
ILS & PAR
What is the difference between an ILS and a PAR?
On an ILS, the instruments provide the pilot with the elevation and azimuth information, where on the PAR the final ATC controller provides the information to the pilot.
What is a non precision approach?
A standard instrument approach procedure in which no electronic glideslope is provided.
What is an example of a non precision approach?
VOR, NDB, LOC, ASR, LDA, SDF (everything but an ILS or PAR)
What is a Final Approach Fix (FAF)?
The fix from which the final approach to an airport is executed. (start of approach)
What is the final approach fix for an ILS/PAR approach?
What is the FAF for a non precision approach?
Maltese cross (x) symbol on government charts
What is the final approach point (FAP)?
The point (on a non precision approach) where the procedure turn is completed and the descent may start.
What is a missed approach point?
A point prescribed in each instrument approach procedure (IAP) at which a missed approach procedure shall be executed if the required visual reference does not exist.
What is the missed approach point for an ILS/PAR approach?
On glideslope at decision height.
How do you know that you are at the missed approach point on a PAR?
Final ATC controller will announce "at decision height."
What is the missed approach point for a non precision approach?
As published on each IAP. (Usually a NAVAID station passage or an elapsed time)
On a precision approach, what is the lowest altitude allowed, called?
Decision height (DH)
On a non precision approach what is the lowest altitude allowed called?
Minimum descent altitude (MDA)
How would you depart an airport that does not have a departure procedure published?
As directed by the Alternate Takeoff Minimums or, if none are published, climb to 400' HAA before turning.
What is the difference between an ADF and an NDB?
ADF is in the aircraft (receiver) and the NDB is on the ground (transmitter).
At a pilot control lighting airport how do you get medium intensity lighting?
5 clicks within 5 seconds
How long will the lights stay on after a pilot uses pilot controlled lighting?
What is an ILS critical area?
An area (designated by taxiway markings) that surface vehicles or aircraft operating on the ground, could cause disturbances to the ILS localizer and glide slope courses.
When is an ILS critical area active?
Control tower active and 800' ceiling, 2 miles visibility.
What are the main differences between a contact approach and a visual approach?
-Contact approach: At the pilots request with 1 mile visibility and clear of clouds.
-Visual approach: Pilot must have airport or preceding aircraft in sight and proceed VMC.
What three things are required to initiate an approach? (COW)
-Cleared for the approach
-Within the "remain within" distance
How does an area forecast differ from a terminal forecast?
An area WX is reported in MSL & Terminal WX is reported in AGL.
