Piper Archer Arrival Procedures Flashcards
What is a “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 judgement of certain visual cues, and depends on a constant final descent airspeed and configuration.
The stabilized approach is required during visual and instrument approaches in ATP aircraft. What must the aircraft be stabilized by?
- 1,000 AGL for an ILS approach
- Descending from MDA for a non-precision approach
- 500’ AGL for a visual approach
What is AGL?
Height Above Ground Level
What is ILS?
Instrument Landing System
What is MDA?
Minimum Descent Altitude
What are the general conditions for a stabilized approach?
- Constant angle glidepath
- Aircraft in landing configuration (flaps set,trim set)
- Engines 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.
What are the conditions for the Archer Stabilized Approach?
- Flaps 25 degrees
- Power set approximately 1500 RPM
- Approximately 350 FPM (feet per minute) descent
- Airspeed 70 KIAS
What is the Aiming Point?
Definition: 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.
What is meant by AIM 2-3-3
2-3-3 are the runway aiming point markings that are broad white stripes located on each side of the runway centerline.
Dealing with Pitch for Arrival Procedures?
Maintain a constant angle glidepath to the aimin point by making pitch adjustments to keep the point stationary in the windshield. If the aiming point moves lower in the windshield, lower the pitch until the aiming point is back in the correct, stationary position. If the aiming point moves toward the top of the windshield, increase the pitch until the aiming point is back in the correct, stationary position.
Addressing Power for the Arrival Procedures?
During a stabilized approach and landing, use power to control deviations from the desired approach speed while maintaining a constant angle glidepath to the aiming point. If the airspeed is too fast, reduce power while maintaining the constant angle glidepath. If the airspeed is slow, add power while maintaining the constant angle glidepath.
Since a constant angle glidepath is a requirement for a stabilized approach, airspeed deviations should be corrected by adjusting power. Changing pitch to correct airspeed deviations during a stabilized approach will cause an excursion from the constant angle glidepath, resulting in an unstable approach.
When does ATP consider landing “assured”?
When the aircraft is lined up and will make the paved runway surface in the current configuration without power.
