Applicability

In plain English

Part 135 is the rulebook for commuter and on-demand operations — what most people call air taxi or charter. It applies when persons or property are carried for compensation in smaller aircraft, on demand, under an operating certificate held by the air carrier.

Key points

• Governs on-demand/commuter (charter) carriage for compensation.
• The operator holds a Part 135 certificate with FAA-approved operations specifications (ops specs).
• Stricter than Part 91 — extra equipment, weather, training and crew rules.

Common pitfalls

• Thinking a commercial certificate alone lets you fly charter — the *operation* needs a 135 certificate.
• Confusing Part 135 (on-demand) with Part 121 (scheduled airline).
