Instrument Approach Procedures - QT

Lesson Quicktakes cover the items that should be memorized from each of the wifiCFI Lessons. They do not cover all of the lesson details in-depth.


VISUAL DESCENT POINT (VDP):

Allows pilot enough time to identify runway environment and make safe/normal descent maneuvers to landing.


If you do not have runway in sight at VDP = You make the decision to execute the Missed Approach.


However, you do not begin the Missed Approach at the VDP. You must wait until reaching the Missed Approach Point.


How to Calculate VDP (if it is not depicted on chart):

HAT/300 = VDP Distance from End of Runway.


AIRCRAFT APPROACH CATEGORIES:


DA/DH VS MDA/MDH:


DA/DH EXAMPLE:


MDA/MDH EXAMPLE:


CIRCLING APPROACH EXAMPLE:


REQUIREMENTS TO DESCEND BELOW DA OR MDA:

Aircraft is in a position to descend using normal descent rates.


Flight visibility is greater than or equal to what is prescribed for approach.


Pilot must have at least one of the following in sight:

The Threshold.

The Threshold Markings.

The Threshold Lights.

The Runway.

The Runway Markings.

The Runway Lights.

The Touchdown Zone.

The Touchdown Zone Markings.

The Touchdown Zone Lights.

The Visual Glideslope Indicator.

The Runway End Identifier Lights (REILs).

The Approach Light System.


If the pilot sees only the Approach Light System, he/she may descend to 100’ above the Touchdown Zone Elevation and then must see one of the elements above.
