Stabilized Approach
Definition: A stabilized approach is one in which the pilot establishes and
maintains a constant angle glidepath towards a predetermined point on the
landing runway. It is based on the pilot’s judgment of certain visual cues, and
depends on a constant final descent airspeed and configuration (FAA-H-8083-
3B, p. 8-9).
The stabilized approach corridor is required during visual and instrument
approaches in ATP aircraft. The aircraft must be stabilized by:
•
1,000' AGL for an ILS approach.
•
Descending from MDA for a non-precision approach.
•
500' AGL for a visual approach.
General Conditions for a Stabilized Approach
•
Constant angle glidepath.
•
Aircraft in landing configuration.
(flaps set, trim set)
•
Engine must be steady at the proper approach power setting.
•
Proper descent angle and rate of descent must be established and
maintained. All available landing aids (ILS, VASI, PAPI, etc.) must be
used. Non-precision approaches may require a slightly steeper angle
until reaching MDA.
•
Airspeed must be stable and within range of target speed plus 10 KIAS.
•
The aircraft will touch down in the first 1,000' of the landing runway. If
this is not assured, a go-around must be executed.
Conditions for the Archer Stabilized Approach
•
Final flap setting
•
Power set approximately 1500 RPM
•
Approximately 350 FPM descent
•
Airspeed 70 KIAS at 400' AGL or descending from MDA
The procedures and parameters listed above are not merely targets, they are
mandatory conditions and limits. Any deviation occurring at or beyond the
beginning of the stabilized approach corridor requires a mandatory go-around.
Aiming Point
The Airplane Flying Handbook defines aiming point as "the point on the ground
at which, if the airplane maintains a constant glidepath, and was not flared for
landing, it would contact the ground."
