## NOTE − 

Several factors affect the ability of the pilot to acquire and maintain the visual references specified in 14 CFR Section 91.175(c), even in cases where the flight visibility may be at the minimum derived by TBL 10 − 1 − 1. These factors include, but are not limited to: 

1. Cockpit cutoff angle (the angle at which the cockpit or other airframe structure limits downward visibility below the horizon). 

2. Combinations of high MDA/DH and low visibility minimum, such as a conventional nonprecision approach with a reduced helicopter visibility minima (per 14 CFR Section 97.3). 

3. Type, configuration, and intensity of approach and runway lighting systems. 

4. Type of obscuring phenomenon and/or windshield contamination.
