Approach Charts & Instrument Approach Plates Flashcards
Prove that your charts are current.
Check the effective and expiration dates printed on the chart. For enroute charts and approach plates, verify the dates in the legend or the top/bottom margin. Digital charts (e.g., ForeFlight) often update automatically, but you must confirm synchronization with the current cycle.
Ref: AIM 5-1-16
What does the number on the farthest top-right corner of your approach plate stand for?
The number represents the revision number of the chart, indicating how many updates the chart has undergone since its original publication.
Ref: Instrument Flying Handbook (IFH), Chapter 5
What are the different sections of an approach plate called? (4)
Briefing Strip: Includes essential information like airport name, procedure title, and frequencies.
Plan View: Overhead depiction of the procedure with navaids, waypoints, and course lines.
Profile View: Side-view diagram showing altitudes and distances for the approach.
Minimums Section: Lists minimum altitudes for various categories and any applicable notes.
Ref: IFH, Chapter 5
When an approach procedure title contains more than one navigational system separated by a slash, what does that mean?
It indicates that the approach can be flown using either system, but not both simultaneously (e.g., “VOR/DME RWY 27” requires both VOR and DME capabilities).
Ref: AIM 5-4-5
What is the significance of a blank triangle with a white “A” or a “T” on the notes section of an approach chart?
White “A”: Indicates alternate minimums are published for the airport. Check the alternate minimums section for details.
“T”: Indicates takeoff minimums or obstacle departure procedures are published.
Ref: AIM 5-4-1
What does MSA mean?
Minimum Safe Altitude (or Minimum Sector Altitude). It is depicted on approach charts and provides 1,000 feet of obstacle clearance within a specific radius (e.g., 25 NM) from a navigation facility or waypoint.
Ref: AIM 5-4-7
What does MSA guarantee?
It guarantees obstacle clearance but does not ensure NAVAID signal reception or ATC communication coverage.
Ref: AIM 5-4-7
What does MALSR stand for?
Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights. It assists pilots in aligning with the runway during low-visibility conditions.
Ref: IFH, Chapter 6
What does MIRL and HIRL stand for?
MIRL: Medium Intensity Runway Lights.
HIRL: High Intensity Runway Lights.
These systems improve runway visibility in various weather conditions.
Ref: AIM 2-1-2
What is ARP?
Airport Reference Point. It is the geographic center of the airport’s runway configuration, used for planning and charting.
Ref: AIM Glossary
What is TDZE?
Touchdown Zone Elevation. It is the highest point in the first 3,000 feet of the landing surface. Used to calculate approach minimums.
Ref: AIM 5-4-7
What is RVR? How do you convert it to visibility?
Runway Visual Range (RVR) measures horizontal visibility along a runway. Conversion depends on lighting and specific regulations. For example, RVR 1,600 feet roughly equals 1/4 statute mile visibility.
Ref: AIM 5-4-3
What is HAT? HAA?
HAT: Height Above Touchdown, used for precision approaches.
HAA: Height Above Airport, used for circling approaches.
Ref: IFH, Chapter 5
What is the difference between DA and DH?
DA: Decision Altitude, an MSL altitude for precision approaches.
DH: Decision Height, an AGL height for older systems. Both indicate the point where a decision to land or go around is made.
Ref: IFH, Chapter 5
What is the difference between MDA and MDH?
MDA: Minimum Descent Altitude, expressed in MSL.
MDH: Minimum Descent Height, expressed in AGL.
Used for non-precision approaches.
Ref: IFH, Chapter 5
What does a Maltese Cross represent?
It marks the Final Approach Fix (FAF) for non-precision approaches.
Ref: AIM 5-4-7
What does IAF stand for?
Initial Approach Fix. It is the starting point of an instrument approach procedure.
Ref: AIM 5-4-6
When is a procedure turn not required?
Cleared for a straight-in approach.
Flying a NoPT route.
Radar vectors to final.
Holding pattern substitutes the turn.
Ref: AIM 5-4-9
Have the student pull up an arrival into airport KHYI, and ask how they would execute it.
Answer: Review the STAR (Standard Terminal Arrival Route) for KHYI. Identify transition points, altitudes, and speed restrictions. Confirm all waypoints are loaded in the FMS or GPS. Monitor ATIS/AWOS for active runways and approach procedures. Brief the approach and ensure compliance with ATC instructions. Verify crossing restrictions and maintain situational awareness using the chart.
Ref: AIM 5-4-1
What are the segments of an instrument approach?
Initial Segment: Begins at the Initial Approach Fix (IAF) and transitions to the intermediate segment.
Intermediate Segment: Begins at the Intermediate Fix (IF) and aligns the aircraft with the final approach course.
Final Segment: Begins at the Final Approach Fix (FAF) and leads to the missed approach point or landing.
Missed Approach Segment: Begins at the missed approach point (MAP) or decision altitude (DA).
Ref: AIM 5-4-5
Where does the initial segment begin?
At the Initial Approach Fix (IAF).
Ref: AIM 5-4-5
Where does the intermediate segment begin?
At the Intermediate Fix (IF) or where the aircraft is inbound and aligned with the approach course.
Ref: AIM 5-4-5
Where does the final segment begin?
At the Final Approach Fix (FAF) for non-precision approaches or at the glide slope intercept for precision approaches.
Ref: AIM 5-4-5
Where does the missed approach segment begin?
At the Missed Approach Point (MAP) for non-precision approaches or at the Decision Altitude (DA) for precision approaches.
