TBM 940: Systems, Performance and Ownership Guide

Quick answer: The Daher TBM 940 is a pressurized, single-engine turboprop introduced with autothrottle and later offered with Garmin’s HomeSafe emergency autoland capability. Its roughly 330-knot class maximum cruise helped narrow some trip-time differences with light jets, but it does not “embarrass” them. Cabin, payload, runway, altitude, weather, training and operating economics are different. The 940 is now principally a used-aircraft choice; Daher’s newer TBM 960 represents the current production evolution.

This guide explains what distinguishes the TBM 940, how it differs from nearby TBM models, and what buyers should verify in systems, training and records.

What is the TBM 940?

The TBM 940 is a low-wing, pressurized, retractable-gear turboprop manufactured by Daher. It uses a Pratt & Whitney Canada PT6A-series engine, a five-blade propeller and Garmin G3000 integrated avionics. The cabin is arranged for a pilot and several passengers, subject to the installed interior and weight limits.

The 940 followed the TBM 930 and added automatic power-control capability. Later 940 aircraft incorporated HomeSafe emergency autoland. Equipment and software status vary by serial number and upgrades, so buyers must verify the individual airplane.

TBM 940 versus TBM 930 and 960

Model	Practical distinction	Buyer’s key check
TBM 930	G3000-era predecessor without the 940’s original autothrottle distinction	Avionics, upgrades, maintenance status and price
TBM 940	Autothrottle and later HomeSafe availability	Exact installed system, software and training requirements
TBM 960	Current-generation evolution with a PT6E engine and new propeller/system integration	Acquisition cost versus newer support and capability

Model labels alone do not reveal configuration. Service bulletins, optional equipment, avionics software and interior changes can narrow or widen the differences.

What autothrottle does

Autothrottle can command engine power in supported phases and modes, reducing some manual power-management workload. It does not remove the pilot’s responsibility to monitor torque, temperature, propeller behavior, mode annunciation and aircraft energy.

Training should cover engagement logic, mode transitions, limits, disconnects and abnormal behavior. Automation surprises usually arise when the pilot expects a different mode than the system is actually using.

HomeSafe emergency autoland

HomeSafe is intended to support an emergency landing if the pilot becomes incapacitated or occupants activate the system under appropriate circumstances. It integrates navigation, automation, communications and landing functions to select a suitable airport and conduct an automated approach and landing.

It is not a normal substitute for qualified pilots, recurrent training or responsible dispatch. Buyers should verify whether the individual 940 has the system, its software and maintenance status, and how training addresses activation and passenger briefing.

Performance versus light jets

A fast turboprop can produce competitive block times on shorter trips because it may use closer airports and spend less time climbing to jet cruise altitude. Light jets generally offer higher cruise speeds and different altitude capability on longer missions.

Trip comparison should include:

Distance and winds
Departure and destination runway requirements
Climb, cruise and descent time
Passenger and baggage payload
Fuel reserves and alternates
Weather and icing exposure
Crew, training and total annual cost

A maximum cruise number alone does not establish the faster or more economical door-to-door trip.

Payload and cabin planning

The TBM cabin is smaller than many light jets and larger utility turboprops. Passenger comfort depends on seating configuration, occupant size, baggage and trip duration. Full fuel and all seats may not be available together in every configuration.

Use the individual empty weight and calculate passengers, bags, fuel, center of gravity, runway requirement and climb. Pressurized speed is valuable only when payload and weather permit the intended mission.

Single-engine turbine risk

The PT6A family has extensive operational history, but engine failure remains a planning case. Altitude can increase glide options; terrain, night, low weather and water can reduce them. Route selection and personal or operator minimums should reflect the consequences.

Pilots need aircraft-specific memory items, checklists, glide planning, restart knowledge and landing-site decisions. Engine reputation does not replace recurrent simulator or in-aircraft training.

Training and single-pilot workload

The TBM is commonly associated with owner-pilot and single-pilot operation, subject to qualifications, regulations, insurance and aircraft approval. High speed compresses decision time. Pressurization, weather radar, ice protection, avionics, autothrottle and engine systems create workload even when automation is functioning.

Initial and recurrent training should address normal systems, automation management, rejected takeoff, engine failure, emergency descent, icing, unreliable indications and HomeSafe procedures where installed. Legal minimums are not a proficiency plan.

Operating-cost reality

Internet hourly figures often omit fixed costs or assume utilization that does not match an owner. Fuel, engine reserves or program enrollment, propeller, scheduled inspections, calendar items, insurance, hangar, databases, training and unscheduled maintenance all belong in the budget.

A used 940 with an attractive purchase price may be approaching major inspections or component limits. Maintenance tracking and a current status report are more useful than an average cost claim.

Pre-purchase priorities

Verify serial-number configuration. Confirm HomeSafe, avionics, software, engine and options.
Reconcile maintenance status. Review airframe, engine, propeller and life- or calendar-limited items.
Check program enrollment and transfer. Understand coverage, exclusions and future costs.
Review damage and operating history. Examine repairs, environment and utilization.
Test actual payload. Use the current empty weight, seating and intended trip.
Confirm training and insurance. Obtain real requirements and quotes before closing.
Plan support. Identify nearby authorized or type-experienced maintenance and downtime logistics.

TBM 940 versus Pilatus PC-12

The TBM 940 emphasizes high speed in a compact cabin. The Pilatus PC-12 emphasizes cabin volume, cargo-door utility and broader runway missions. Both are pressurized single-engine turboprops, but their payload, cabin, runway and acquisition priorities are different.

Frequently asked questions

Is the TBM 940 still in production?

The TBM 960 is the current production evolution. The 940 remains relevant on the used market and may have many modern capabilities, depending on configuration.

Does every TBM 940 have HomeSafe?

No assumption should be made from the model label alone. Verify the individual aircraft’s installed equipment, software and records.

Can the TBM 940 be flown single-pilot?

Many operations are structured for a qualified single pilot, subject to current regulations, insurance, aircraft approval and operator policy. Training and recency remain critical.

Is the TBM cheaper than a light jet?

It often burns less fuel and has one engine, but total economics depend on purchase price, utilization, maintenance, programs, crew, insurance and mission. Compare complete annual budgets.
