Types of IAP’s

Question 1

What are Precision Approaches?

Answer 1

-Meets ICAO Annex 10 requirements
-Has vertical and lateral guidance
-Has a DA

Question 2

Types of Precision Approaches?

Answer 2

-Precision approach radar (PAR)
-Instrument landing system (ILS)
-GBAS landing system (GLS)
-Ground controlled approach (GCA)
-Microwave landing system

Question 3

What are APVs?

Answer 3

-Approach with vertical and lateral guidance
-Not a precision approach
-Doesn’t get data from ground sources (Does not mean ICAO Annex 10)
-Has a DA

Question 4

Type of APVs?

Answer 4

-LNAV/VNAV (Requies WAAS)
-LPV (WAAS GPS) (more precise, tapers down as you get closer)
-LDA+ Glide Slope

Question 5

What are Non-precision approaches?

Answer 5

-Have lateral guidance only
-Have an MDA

Question 6

Types of Non-precision approaches?

Answer 6

-Localizer
-Localizer Type Directional Aid (LDA)
-Simplified Directional Facility (SDF)
-LNAV (most basic)
-LP (tapers off, like an LPV just no vertical)
-VOR (use radial to fly an approach)
-NDB Approach
-Approach Surveillance Radar (only lateral guidance)

Question 7

What are the different categories for approaches and their speeds?

Answer 7

-Category A: Speed 90 knots or less. (Us)
-Category B: Between 91 and 120 knots.
-Category C: Between 121 and 140 knots.
-Category D: Between 141 knots and 165 knots.
-Category E: Speed 166 knots or more.

Question 8

Difference between Localizer Type Directional Aid (LDA) and a Simplified Directional Facility (SDF)

Answer 8

-Localizer Type Directional Aid (LDA) are not aligned with the runway but are more accurate
-Simplified Directional Facility (SDF) 6-12 degrees wide and are less accurate

Question 9

What’s the Final Approach Fix (FAF) on a precision approach?

Answer 9

Lightning bolt

Question 10

What’s the Final Approach Fix (FAF) on a non-precision approach?

Answer 10

Maltese cross

Question 10

What’s the Final Approach Fix (FAF) on an APV approach?

Answer 10

Lightning bolt

Question 10

Difference between Approach Surveillance Radar (ASR) and Precision approach radar (PAR)

Answer 10

-ASR are non-precision approaches with no vertical guidance and an MDA.
-PAR are a precision approach with a DA
-Minimums can be found in the TPP

Question 11

DA vs DH vs MDA

Answer 11

-DA uses MSL (must go around once you hit DA)
DH- Uses AGL (must go around once you hit DH)
MDA- Uses MSL (can contiunte on until MAP)

Question 11

What are Step Down Fixes?

Answer 11

-Step-down fixes on an approach help you safely descend on an approach and remain stable
