Overview Of Aviation Rules For Commercial Jets

A Part 135 certificate issued by the Federal Aviation Administration (FAA) authorizes the operation of on-demand air service. From small single-aircraft operators to significant operators, 135 certification is mandatory to convey freight to larger Part 121 air carriers. Many Part 135 operators provide essential supply and cargo transport to isolated places to sustain community survival. To execute this program, Part 135 air carriers must have an FAA-certified strategy to carry hazardous substances (dangerous goods). This program must cover all parts of the acceptance, handling, and transportation process, as well as part 135 training.

What is Part 135?

The objective of Part 135 FAR regulations is to impose uniform and enforced guidelines for quality standards, safety, and professionalism all across the private aviation charter industry. The maintenance of aircraft, insurance requirements, the qualifications and training of pilots, and safety protocols are mainly controlled by Part 135 regulations.

Part 135 certification is also needed for the execution of approved hazardous materials programs. Hazardous Materials Principal Inspectors (HMPIs), who are responsible for closely monitoring the hazardous materials programs of Part 135 air carriers, are assigned with this certification. These air carriers accept, handle, and transport dangerous substances.

Importance of Part 135 Regulations

Part 135 Federal Aviation Regulations were implemented to protect passengers and improve aviation safety by creating uniform policies and standards for privately operated aircraft and air transport.

Part 91 Vs. Part 135 operations

The critical distinction between Part 91 and Part 135 operations are safety guidelines and requirements applied to the flights. Generally, private charter services are regulated by FAR Part 135 standards, while privately owned aircraft used for personal travel are controlled by FAR Part 91. In comparison to Part 91, Part 135 operations are more complicated. Therefore, part 135 training is crucial for the operators.

About Part 135 Certification Program

Because most business aircraft are built for private commercial passenger travel, the FAA issues the bulk of commercial permits for Part 135. These certifications are commonly referred to as “charter certificates” (though their technical name is “air charter certificates”). To comply with the FAA’s Federal Aviation Regulation (FAR) for Part 135 Basic and Periodic training, operators and their pilots must take part 135 training.

The course will equip them with the following knowledge:

  • Review of FAR Parts 61, 91, and 135 (Control over operations)
  • The difference between on-demand and commuter operations
  • Conditions and conditions for authorized on-demand operations
  • Flight crew qualification and requisite operational experience
  • Crew duty and downtime
  • Procedures for weighing and balancing
  • HAZMAT overview
  • Equipment requirements for aircraft, including specific operations
  • Weather analysis (Managing and averting severe weather)
  • Specifications for takeoff and regulations on landing
  • Standard operating procedures and IFR protocols and performance standards
  • Procedures and systems for air traffic control
  • Navigation tools and techniques


This industry has a wide range of business models, each of which offers a different level of security and safety and is subject to a different set of legal regulations. The officials often conduct a Conformity Check on the aircraft to make sure that it complies with Part 135 regulations regarding both the aircraft and maintenance records. The operators in control must therefore have a part 135 Training certificate to comply with aviation laws.
