Airport requirements

This regulation sets minimum standards for airports used in Part 135 operations (commuter and on-demand flights).

Basic requirement: Certificate holders may only use airports adequate for their operation, considering size, surface, obstructions, and lighting.

Night passenger operations have stricter rules: When carrying passengers at night, pilots must determine wind direction before takeoff or landing using an illuminated wind indicator, ground communications, or (for takeoff only) personal observation. Additionally, the usable area must be clearly marked:

• Airplanes: Boundary or runway marker lights required
• Helicopters: Boundary/runway marker lights or reflective material acceptable

If an operator wants to use flare pots or lanterns instead of standard lighting to mark the takeoff/landing area, they need specific FAA approval.

These requirements ensure pilots have adequate visual references and critical weather information when operating passenger flights at night, reducing the risk of runway excursions or obstacles strikes in low-visibility conditions.
