- Chapter 4. Air Traffic Control › Section 4. ATC Clearances and Aircraft Separation › 4-4-15. Use of Visual Clearing Procedures and Scanning Techniques
threat increases directly as more time is spent looking outside the aircraft. One must use timesharing techniques to effectively scan the surrounding airspace while monitoring instruments as well. d. Since the eye can focus only on a narrow viewing area ... effective scanning is accomplished with a series of short, regularly spaced eye movements that bring successive areas of the sky into the central visual field. Each movement should not exceed ten degrees, and each area should be observed…

Example of a Chart Note 4. A straight-in aligned procedure may be restricted to circling only minimums when an excessive descent gradient necessitates. The descent angle between the FAF/stepdown fix and the Circling MDA must not exceed the maximum ... descent angle allowed by TERPS criteria. A published VDA on these procedures does not imply that landing straight ahead is recommended or even possible. The descent rate based on the VDA may exceed the capabilities of the aircraft…
- Chapter 5. Air Traffic Procedures › Section 4. Arrival Procedures › 5-4-23. Visual Approach
Visual Approach a. A visual approach is conducted on an IFR flight plan and authorizes a pilot to proceed visually and clear of clouds to the airport. The pilot must have either the airport or the preceding identified aircraft ... visibility 3 miles or greater. ATC may authorize this type of approach when it will be operationally beneficial. Visual approaches are an IFR procedure conducted under IFR in visual meteorological conditions. Cloud clearance requirements of 14 CFR section…

These instrument procedures may be designed to guide the helicopter to a specific landing area (Proceed Visually) or to a point-in-space with a “Proceed VFR” segment. 1. An approach to a specific landing area. This type of approach ... missed approach point from which a landing can be accomplished with a maximum course change of 30 degrees. The visual segment from the MAP to the landing area is evaluated for obstacle hazards. These procedures are annotated: “PROCEED VISUALLY FROM…
- Chapter 12: Night Operations › Night Vision › Night Scanning
Night Vision Diet and general physical health have an impact on how well a person can see in the dark. Deficiencies in vitamins A and C have been shown to reduce night acuity. Other factors, such as carbon monoxide poisoning ... smoking, alcohol, and certain drugs can greatly decrease night vision. Lack of oxygen can also decrease night vision as the eye requires more oxygen per unit weight than any other part of the body. Night Scanning Good night visual acuity…
- U.S. TERMINAL PROCEDURES PUBLICATION › CHARTED VISUAL FLIGHT PROCEDURE (CVFP) CHARTS
CHARTED VISUAL FLIGHT PROCEDURE (CVFP) CHARTS CVFPs are charted visual approaches established for environmental/noise considerations, and/or when necessary for the safety and efficiency of air traffic operations. The approach charts depict prominent landmarks, courses, and recommend ed altitudes to specific ... have missed approach segments. CVFPs are named for the primary landmark and the specific runway for which the procedure is developed, such as: RIVER VISUAL RWY 18, STADIUM VISUAL RWY 24. The CVFP charts are divided into planview and notes…
