AA.VII.F.S10
SkillApply adjustments to the published decision altitude (DA)/decision height (DH) and visibility criteria for the aircraft approach category, as appropriate, for factors that include Notices to Air Missions (NOTAMs), inoperative aircraft or navigation equipment, inoperative visual aids associated with the landing environment, etc.

- Chapter 4: Approaches › Final Approach Segment
Final Approach Segment The final approach segment for an approach with vertical guidance or a precision approach begins where the glideslope/glidepath intercepts the minimum glideslope/ glidepath intercept altitude shown on the approach chart. If ATC authorizes a lower intercept altitude ... final approach segment begins upon glideslope/glidepath interception at that altitude. For a non-precision approach, the final approach segment begins either at a designated FAF, which is depicted as a cross on the profile view, or at the point where…
- Chapter 4: Approaches › Aircraft Approach Categories
Note: Helicopter pilots may use the Category A line of minimums provided the helicopter is operated at Category A airspeeds. An airplane is certified in only one approach category, and although a faster approach may require higher category minimums ... used, an airplane cannot be flown to the minimums of a slower approach category. The certified approach category is permanent and independent of the changing conditions of day-to-day operations. From a TERPS viewpoint, the importance of a pilot…
- Chapter 4: Approaches › NDB Approach
Additionally, the final approach course and the extended runway centerline angle of convergence cannot exceed 30° for straight-in approaches. This type of NDB approach is afforded a minimum of 350 feet obstacle clearance. When a FAF is established ... approach, the approach design criteria changes. It also takes into account whether or not the NDB is located on or off the airport. Additionally, this type of approach can be made both moving toward or away from the NDB facility…
- Chapter 4: Approaches › Minimum Descent Altitude (MDA), Decision Altitude (DA), And Decision Height (DH)
Minimum Descent Altitude (MDA), Decision Altitude (DA), And Decision Height (DH) MDA—the lowest altitude, expressed in feet MSL, to which descent is authorized on final approach or during circle-to land maneuvering in execution of a standard instrument approach ... procedure (SIAP) where no electronic glideslope is provided. DA—a specified altitude in the precision approach at which a missed approach must be initiated if the required visual reference to continue the approach has not been established. DH—with respect…
- Chapter 4: Approaches › Visual Approaches
Visual and Contact Approaches To expedite traffic, ATC may clear pilots for a visual approach in lieu of the published approach procedure if flight conditions permit. Requesting a contact approach may be advantageous since it requires less time than ... published IAP and provides separation from IFR and special visual flight rules (SVFR) traffic. A contact or visual approach may be used in lieu of conducting a SIAP, and both allow the flight to continue as an IFR flight…
