Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with glassy water approach and landing.
What the ACS code means
- PA identifies the ACS standard family used for this Private Pilot Airplane document.
- IV identifies Takeoffs, Landings, and Go-Arounds, the Area of Operation.
- J identifies Glassy Water Approach and Landing (ASES, AMES), the Task within that Area.
- K, R, and S identify knowledge, risk-management, and skill elements. The number selects the item; a trailing lowercase letter identifies a listed sub-element.
Knowledge elements

| PA.IV.J.R6 | Distractions, task prioritization, loss of situational awareness, or disorientation. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PA.IV.J.R7 | Gear position in an amphibious airplane. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
Skills elements
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| PA.IV.J.S1 | Complete the appropriate checklist(s). | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S2 | Make radio calls as appropriate. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S3 | Scan the landing area for traffic and obstructions. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S4 | Select a proper approach and landing path considering the landing surface, visual attitude references, water depth, and collision hazards. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S5 | Establish the recommended approach and landing configuration, airspeed, and trim, and adjust pitch attitude and power as required to maintain a stabilized approach. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S6 | Maintain manufacturer’s published approach airspeed or in its absence not more than 1.3 VSO, +10/-5 knots. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S7 | Make smooth, timely, and correct power and control adjustments to maintain proper pitch attitude and rate of descent to touchdown. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S8 | Contact the water in a proper pitch attitude, and slow to idle taxi speed. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.IV.J.S9 | Maintain directional control throughout the approach and landing. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
Difficulty data
Difficulty calibration is ongoing for this Task. A difficulty estimate is published only with a sufficiently large, privacy-preserving first directly recorded assessment sample. Any observed difficulty comes from Checkride AI mock-oral practice assessments and is a practice-data proxy, not an FAA practical-test pass or fail rate.
Difficulty calibration remains ongoing until an item clears the private reporting threshold. Percentages, when available, describe the share who needed review on their first directly recorded assessment. Underlying sample sizes are never published, and historical final states are not backfilled into this measure.
Official task notes
- If a glassy water condition does not exist, the applicant must be evaluated by simulating the Task.
How to use this in a mock oral
A mock examiner can ask you to explain the published elements, apply them to the configured aircraft and airport scenario, identify risks, and defend a decision. The prompts are practice scenarios; they are not claimed to be actual FAA examiner scripts or a prediction of the questions you will receive.
