Chapter 15 - Approach Flashcards
What are the two ways to fly an instrument approach?
Full Procedure or via Radar Vectors
When are you allowed to descend below MDA or DA?
When sufficient visual reference with the runway environment has been established and the aircraft is in a position to execute a safe landing
When are you allowed to descend below 100 ft above the threshold elevation or touchdown zone elevation when using the approach lights as a reference?
The red termination bars or red side row bars are visible and identifiable
When operating with a speed restriction and you recieve clearance to fly an approach, when are you allowed to adjust your speed?
Approach clearances cancel any previously assigned airspeed adjustments. You are expected to make our own airspeed adjustments to complete the approach unless the adjustments are restated.
Where should speed adjustments not be assigned?
Inside the FAF or a point 5 miles from the runway, whichever is close to the runway
As a pilot, are you allowed to deny a speed adjustment? If so, why?
Yes, if the minimum safe airspeed for any operation is greater than the speed adjustment
What is the range of speeds for the initial approach segment for a Cat B aircraft?
120 to 180
What is the range of speeds for the final approach segment for a Cat B aircraft?
85 to 130
What is the max speed for a reversal/racetrack procedure for a Cat B aircraft? ICAO
140
Where do you find information regarding radar approaches?
front of the Terminal Procedures Pub
What is a non-radar approach?
An approach that does not require radar vectoring or radar services on final approach and may or may not provide vertical glideslope guidance
On the plan view of an approach, when are concentric rings used?
When all procedural and terminal route information cannot be depicted to scale
What distance ring is shown when necessary? What does the ring signify?
10NM on low altitude approaches and a 20NM ring on high altitude approaches.
Everything within the ring is shown to scale
What type of obstacle clearance does the ESA provide?
1000 ft obstacle clearance, 2000 ft obstacle clearance in mountainous areas, within 100 nm of the facility
What type of obstacle clearance does the Minimum Sector Altitude provide?
1000 ft obstacle clearance within 25 NM
Does an approach without a FAF still have a VDA?
No
What is TCH?
Threshold Crossing Height, it is the point where the VDA crosses above the threshold
What is a typical TCH?
Between 30 and 50 ft unless required by larger type aircraft
Are all obstructions depicted on the airfield diagram?
No, check NOTAMS, enroute supplement, etc
What is field elevation?
The highest point on any usable landing surface
What is touchdown zone elevation?
The highest point in the first 3000ft of the landing surface
