What is Part 135 Flying? A Guide for Career Pilots

For many pilots, the career path is presented as a straight line: earn your certificates, build flight time, reach airline minimums, and apply to a Part 121 carrier.

But the airlines are only one part of professional aviation.

Part 135 flying includes charter, private aviation, cargo, commuter, and other on-demand operations that can give pilots a very different kind of professional flying experience.

For some pilots, it becomes a long-term career. For others, it is an important step between flight training and the next cockpit.

Understanding what Part 135 actually means can help you decide whether it belongs in your career plan.

What Does “Part 135” Mean?

“Part 135” refers to 14 CFR Part 135, the section of the Federal Aviation Regulations governing commuter and on-demand commercial operations.

The FAA allows Part 135 certificate holders to conduct on-demand operations and, depending on their operating authority, scheduled commuter operations. These operators range from small companies flying a handful of aircraft to larger organizations operating fleets of turboprops and business jets.

In practical terms, when pilots talk about Part 135 flying, they are often talking about operations such as:

• Passenger charter

• Business and private aviation

• Air taxi service

• Cargo operations

• Medical transportation

• Scheduled commuter service

The aircraft can range from piston airplanes and turboprops to sophisticated business jets.

That variety is one of the defining characteristics of the Part 135 world.

How Is Part 135 Different From Airline Flying?

Part 121 airline operations are generally built around a highly structured network: published schedules, established routes, large flight departments, standardized fleets, and major commercial airports.

Part 135 flying can look very different.

An on-demand charter crew might begin the day expecting to fly from Florida to Georgia, receive another passenger request later in the day, reposition the aircraft, encounter changing weather, and finish at an airport they rarely visit.

The schedule, passengers, destinations, aircraft, and mission can change frequently.

That doesn't mean Part 135 operations are less structured from a regulatory standpoint. Part 135 operators operate under FAA-approved authorizations, procedures, training programs, checking requirements, and operating limitations applicable to their particular operation.

What changes is the operational environment.

Instead of repeatedly flying the same routes between large airports, a Part 135 pilot may be expected to become comfortable operating into a much wider variety of airports and situations.

What Does a Part 135 Pilot Actually Do?

The answer depends heavily on the operator and aircraft, but Part 135 pilots often have responsibilities that extend beyond manipulating the flight controls.

A normal trip may involve reviewing weather, NOTAMs and airport conditions; evaluating fuel and alternates; calculating aircraft performance and weight and balance; coordinating with passengers, dispatch or company personnel; preparing the cabin or aircraft; loading baggage; flying the mission; managing changing weather or passenger requests; and coordinating fuel or ground handling at the destination.

At some companies, many of those functions are supported by dedicated departments.

At smaller operators, pilots may be much closer to the entire operation.

That can make Part 135 flying demanding, but it can also expose a developing professional pilot to something valuable:

the decisions behind the flight, not just the flight itself.

Part 135 Flying Is Often About Decision-Making

Consider a relatively simple cross-country flight.

A training flight might primarily be evaluated on whether you planned properly, flew accurately, communicated effectively, and complied with regulations.

A professional charter flight adds another layer.

Now there may be passengers expecting to arrive at a particular place at a particular time. Weather may be deteriorating. Fuel availability may be limited. The destination runway may be short. Baggage may affect weight and balance. An alternate airport may create transportation problems for the passengers.

The pilot still has one overriding responsibility: operate the aircraft safely and within the limitations of the operation.

Commercial pressure does not change that.

Part 135 flying therefore rewards pilots who can combine technical flying ability with judgment, communication, planning, and professionalism.

The Passenger Is Part of the Mission

One of the biggest differences between many Part 135 jobs and other early-career flying positions is proximity to the customer.

In private aviation, the people sitting behind you may be the individuals directly paying for the flight.

They may walk onto the ramp minutes before departure and speak directly with the crew. You might explain a weather delay, help with baggage, answer questions about the flight, or coordinate a change in destination.

That means professional appearance, communication, discretion, and customer service can matter alongside stick-and-rudder ability.

A strong Part 135 pilot understands that these responsibilities are not in conflict with safety.

Good customer service does not mean saying yes to everything.

Sometimes the most professional answer a pilot can give is:

“We can't safely do that today, but here is what we can do.”

What Aircraft Do Part 135 Pilots Fly?

There is no single Part 135 aircraft.

Operators can fly piston airplanes, turboprops, helicopters, and business jets depending on their certificates and authorizations. The FAA's Part 135 framework covers a wide range of on-demand and commuter operations.

For pilots interested in private aviation, that creates a career ladder that can potentially move through progressively larger and more capable aircraft.

A pilot might begin in a piston twin or light turboprop, move into larger turboprops or light jets, and eventually transition into midsize or large-cabin business aircraft.

The exact progression varies dramatically between operators.

That's why pilots should look beyond the aircraft currently attached to a job posting and ask a better question:

Where can this position lead?

Do You Need 1,500 Hours to Fly Part 135?

No.

Part 135 pilot qualification requirements depend on the position, aircraft, and type of operation.

For example, under the current regulation, many VFR Part 135 PIC positions require at least 500 hours total time, 100 hours cross-country of which 25 hours were at night, along with the appropriate commercial certificate, ratings, and other qualifications. Certain passenger-carrying operations involving turbojets and other specified aircraft require an ATP certificate for the PIC.

Second-in-command requirements can be different. In general, §135.245 requires an SIC to hold at least a commercial pilot certificate with the appropriate category and class ratings and an instrument rating, subject to the additional qualifications applicable to the operation.

But regulatory minimums are only part of the picture.

Individual operators can establish higher hiring minimums based on their aircraft, training program, customer requirements, insurance, operating environment, or internal standards.

So seeing a regulatory minimum does not mean every operator will hire at that number.

Why Multi-Engine and Instrument Experience Matter

Total flight time tells an operator how much you have flown.

It does not tell them everything about what you have been doing during those hours.

Part 135 operations frequently place significant value on experience that resembles the environment in which the company actually operates: cross-country flying, instrument procedures, multi-engine aircraft, crew coordination, weather decisions, unfamiliar airports, and professional cockpit procedures.

Imagine two pilots with similar total time.

One has spent most of the previous several hundred hours flying repetitive local VFR missions.

The other has substantial recent experience planning cross-country IFR flights, working in a two-pilot environment, operating multi-engine aircraft, evaluating weather and alternates, and making real operational decisions.

Those logbooks may show similar totals.

They do not necessarily tell the same story.

Is Part 135 Just a Stepping Stone to the Airlines?

It can be.

But it doesn't have to be.

Some pilots use Part 135 employment to build turbine experience, multi-engine time, PIC time, and professional operating experience before moving to Part 121 airlines.

Others discover that they prefer private aviation.

Part 135 flying can offer smaller crews, different destinations, greater variety, closer interaction with passengers, and career opportunities throughout the business aviation industry.

Neither path is automatically better.

They are simply different careers.

The more useful question is:

What kind of professional flying do you actually want to do?

What Should a Future Part 135 Pilot Be Building?

If Part 135 flying interests you, don't think only about reaching the next total-time number.

Think about the pilot you are becoming along the way.

Build experience that forces you to plan.

Build instrument proficiency.

Become comfortable operating outside your home airport.

Learn how weather changes a mission.

Develop disciplined checklist habits.

Learn to work effectively with another pilot.

Understand performance, fuel planning, weight and balance, alternates, and operational limitations.

And become someone another pilot would trust sitting in the seat next to them when the weather is down, the passengers are waiting, and the original plan no longer works.

Those qualities are difficult to summarize with a single number in a logbook.

They are also some of the qualities professional operators are trying to identify.

The Goal Is More Than Reaching a Minimum

Flight training has to begin with certificates and ratings.

But a professional aviation career eventually becomes about much more than passing checkrides.

It becomes about judgment.

Consistency.

Crew coordination.

Professionalism.

And your ability to make good decisions when there isn't an instructor sitting beside you telling you what happens next.

For pilots interested in charter and private aviation, Part 135 can be one of the first environments where all of those pieces come together.

So as you plan the next stage of your training, don't ask only:

“How quickly can I build the hours?”

Ask:

“What do I want those hours to prepare me to do?”
