Lesson 21

Question 1

SIAPs are designed to:

Answer 1

• provide an IFR descent from an en route environment to a point where a safe landing can be made
• guide aircraft through IFR conditions to a point where the runway environment can be seen

Question 2

How often are SIAPs published?

Answer 2

every 56 days

Question 3

SIAP charts provide the method to descend and land safely in _________ conditions.

Answer 3

low visibility

Question 4

Name the 4 segments of an instrument approach.

Answer 4

• Initial
• Intermediate
• Final
• Missed

Question 5

Standard Instrument approach procedures must begin ________.

Answer 5

at an initial approach fix (IAF), or final approach fix (FAF) if there is not an IAF.

Question 6

Initial Approach Segment

Answer 6

b/t initial approach fix and intermediate approach fix or the point where the aircraft is established on the intermediate course or final approach course

Question 7

Intermediate Approach Segment

Answer 7

the segment between the intermediate fix or point and the final approach fix

Question 8

Final Approach Segment

Answer 8

segment b/t the final approach fix or point and the runway, airport, or missed approach point

Question 9

Missed Approach Segment

Answer 9

segment b/t the missed approach point or the point of arrival at decision height and the missed approach fix at the prescribed altitude

Question 10

Missed Approach Segment

Answer 10

segment b/t the missed approach point or the point of arrival at decision height and the missed approach fix at the prescribed altitude

Question 11

IAPs are classified as either _____ or _____.

Answer 11

precision; non-precision

Question 12

What approach provides both lateral and vertical guidance with a ground based support infrastructure?

Answer 12

precision approaches

Question 13

What approach provides lateral course guidance only?

Answer 13

non-precision approaches

Question 14

Name the 2 types of Precision Approaches:

Answer 14

PAR / ILS

Question 15

Name the types of Non-Precision Approaches:

Answer 15

• RNAV (GPS)
• LOC
• VOR
• VOR/DME
• TACAN
• NDB
• ASR

Question 16

What are the primary components of the ILS System?

Answer 16

• localizer (lateral guidance)
• glideslope (vertical guidance)
• marker beacons (provide range info along the appch path)
• approach lights (assist w/ transition from instrument to visual)

Question 17

T/F: An aircraft must be in instrument flight conditions to execute an IAP.

Answer 17

False

Question 18

An approach is termed “non-precision” because it ______.

Answer 18

provides lateral guidance only

Question 19

The purpose of an ______ is to portray the aeronautical data which is required to execute SIAPs to airports.

Answer 19

SIAP Chart

Question 20

The 6 sections of the IAP are:

Answer 20

• margin info
• pilot briefing information
• plan view
• airport diagram
• profile view
• minimums section

Question 21

Minimum Safe Altitude (MSA)

Answer 21

emergency altitude to be used within 25 NM of the NAVAID upon which the approach is predicated; ensures 1,000 ft obstruction clearance, but does not ensure NAVAID freq reception

Question 22

Terminal Arrival Area (TAA)

Answer 22

for use by aircraft equipped with advanced nav such as a Flight Management System or Global Positioning System; replaces the MSA and provides minimum altitudes with standard obstacle clearance depending upon the direction from which the aircraft is arriving

Question 23

Decision Altitude (DA)

Answer 23

altitude at which a decision must be made during a precision approach to either continue the approach or execute a missed approach

Question 24

Minimum Descent Altitude (MDA)

Answer 24

lowest altitude to which descent is authorized on final approach where no electronic glide slope is provided (non precision approach)

Question 25

What does the lightning bolt depict?

Answer 25

Final Approach Fix (FAF) when flown as a full ILS approach with glide slope

Question 26

What does the maltese cross depict?

Answer 26

Final Approach Fix (FAF) when flown as a localizer approach (when the glide slope is inoperative) (non precision approach)

Question 27

What does the maltese cross depict?

Answer 27

Final Approach Fix (FAF) when flown as a localizer approach (when the glide slope is inoperative) (non precision approach)

Question 28

Height Above Touchdown Zone (HAT)

Answer 28

height of the decision height or minimum descent altitude about the highest runway elevation in the touchdown zone (first 3000 ft of the runway)

Question 29

Height Above Airport (HAA)

Answer 29

height of minimum descent altitude above the published airport elevation

Question 30

In a radar environment, to vector an aircraft for a visual approach the ceiling at the airport of intended landing must be ________ above the minimum vectoring altitude and the visibility is 3 miles or greater.

Answer 30

500 ft

Question 31

Contact Approach

Answer 31

approach wherein an aircraft on an IFR flight plan having an atc authorization, operating clear of clouds with at least 1sm flight visibility and a reasonable expectation of continuing to the destination airport in those conditions, may deviate from the instrument approach procedure and proceed to the destination airport by visual reference to the surface
