Instruments (starting at IN109-IN205, 217)* Flashcards
What is a low altitude instrument approach?
Low altitude instrument approaches transition aircraft from the low- altitude environment to a point where the runway can be visually acquired and a safe landing executed
What do low altitude instrument approaches provide?
terrain clearance, separation from other IFR aircraft, and guide the aircraft to a published Final Approach Fix(FAF)
What are the 3 categories of low altitude instrument approach procedures?
Precision approaches, Approaches with Vertical Guidance (APV), and Non-precision approaches
What are the 5 segments to an instrument approach procedure?
Arrival, Initial, Intermediate, Final, Missed Approach
What are the two ways an instrument procedure can be flown? Why would a pilot fly each one?
“full procedure” approach or with ATC assistance via radar vectors
-Full procedure approaches may be requested by the pilot but are most often used in areas without radar coverage. A full procedure approach also provides the pilot with a means of completing an instrument approach in the event of a communication failure
What is a precision approach?
an instrument approach based on a navigation system that provides COURSE and GLIDEPATH deviation information meeting the precision standards of ICAO
What is an approach with vertical guidance?
an instrument approach based on a navigation system that is not required to meet the precision approach standards of ICAO Annex 10, but provides course and glidepath deviation information
What is a non-precision approach?
an instrument approach based on a navigation system which provides course deviation information but no glidepath deviation information
What are the two types of course reversal procedures?
Procedure turn and Racetrack (Holding In Lieu of Procedure Turn)
What is a terminal routing?
Terminal routes, which originate at the IAF, are depicted with course, minimum altitude, and distance to the initial fix.
Essentially, these routes accomplish the same thing as feeder routes but originate at an IAF, whereas feeder routes terminate at an IAF
If you are using a terminal routing and are cleared for the approach, are you considered established on the approach?
Yes, you may descend to the published terminal routing altitude
What is RNAV operations?
RANDOM NAVIGATION (RNAV) is “point to point” navigation where you do not need to go from ground station (like a VOR or TACAN) to ground station, but you go in a straight lines. The Global Positioning System (GPS) is a form of RNAV
As a conservative technique, when can you consider yourself in the terminal area?
if you are within 30 NM of the destination, below Class A airspace, or are using a published procedure for navigation (IAP/STAR/SID, etc.).
If RAIM outages are predicted for more than __ minutes along the route of flight, the flight must rely on other approved equipment
5 minutes
What is the T-6A maneuvering speed?
120-150 KIAS
When executing any low altitude approach procedure, you are expected to slow to maneuvering speed for your aircraft prior to reaching the IAF
If you are using a terminal routing and are cleared for the approach, you are considered established on the approach. (T/F)
a. True
If using GPS in the terminal area, pilots should not comply with ATC instructions to proceed direct to a point. (T/F)
b. False
TAA area lateral boundaries are identified by magnetic courses _____ the IF (IAF).
a. TO
b. FROM
c. abeam
d. parallel to
a. TO
What airspeed do you maintain prior to configuring when flying a low altitude approach in the T-6A?
b. 120-150 KIAS
Low altitude approaches enable the aircraft to transition from instrument flight conditions to a visual landing while providing
a. terrain clearance and separation from other IFR aircraft.
b. terrain clearance only.
c. separation from all aircraft.
d. separation from VFR aircraft.
a. terrain clearance and separation from other IFR aircraft.
When a TAA is published, it replaces the __________ for the approach procedure.
a. MEA
b. MSA
c. MRA
d. MOCA
b. MSA (minimum safe altitude)
The minimum altitude on this approach you may descend to prior to the FAF is?
b. 2900 feet
What altitude can you descend to if you are using a feeder facility and are cleared for the approach?
a. You can descend to the altitude depicted on the feeder route.
b. You can descend to the IAF crossing altitude 10 NM from the IAF.
c. You can descend to the IAF altitude when halfway between the feeder fix and IAF.
d. You can descend only to the IAF altitude when crossing the IAF.
a. You can descend to the altitude depicted on the feeder route.
What is the “Radar Pattern?” Why is it used?
Operating in the radar pattern simply implies that you are assigned vectors (headings), altitudes, and other essential information from a ground-based controller. The radar pattern is used to vector aircraft to the final approach segment of both non-radar approaches (ILS, VOR, LOC) and radar approaches (ASR or PAR)
