Instrument approach procedures and IFR landing minimums

When flying under Part 135 (commercial operations like charter or air taxi), pilots must follow the specific instrument approach procedures and weather minimums listed in their company's operations specifications—not just the standard published minimums.

This means you cannot simply use the approach minimums printed on government approach charts. Your company's OpSpecs may authorize lower minimums (such as Category II or III approaches) if properly equipped and trained, or they may require *higher* minimums than published based on aircraft equipment, pilot experience, or company policy.

In practice, before conducting any instrument approach under Part 135, you must verify that:

• The current weather meets your OpSpecs minimums for that specific approach
• You're using the approach procedures your company is authorized to fly

This regulation ensures commercial operators maintain the safety standards their FAA-approved operations specifications require, which may differ from standard Part 91 operations.
