Compact & Self Contained

EngineSense is a compact self-contained device that is constantly monitoring the physics of motion of your airplane in order to detect an engine failure.  EngineSense detection and identification can be complete in the first couple of seconds after the event, which is about how long your brain will take to register that something has occurred.  EngineSense is small and lightweight offering maximum flexibility in cockpit placement.

Patented Technology

As multi-engine pilots we are trained to handle engine failures in a variety of scenarios.  The EngineSense patented technology takes the guesswork out of identifying which engine has potentially failed and which is the good engine.  For most multi-engine aircraft, getting the failed engine propeller feathered is critical for sustained flight.

EngineSense gives you the confidence that the engine you are feathering and shutting down is the correct one.

EngineSense Components

EngineSense comes with two components.  The primary display unit with integrated sensors that monitor all aspects of the physics in the aircraft.  The second is a set of replacement knobs for the engine propellor control levers that wirelessly communicate with the primary display unit and in the event of a failure will illuminate the knob of the suspected failed engine.

Frequently Asked Questions

Does EngineSense replace my emergency procedure checklist?

No, in the event of a suspected engine failure the pilot should always use their standard emergency procedure and training for the given problem.  EngineSense is only used to inform the pilot of its calculated suspect failed engine so that the pilot can use that as a data point while dealing with the emergency.

Does EngineSense work without the lighted propeller knobs?

Yes, EngineSense has dedicated indicator lights on the main unit that operate independent of the lighted knobs.  In the event of a knob communication or battery issue, the main unit will still indicate a suspected failure event and illuminate the appropriate propeller knob.

How does EngineSense work?

After installing the propellor knobs and placing the EngineSense unit at a convenient location in the cockpit, the pilot simply needs to hit the power button to enable real time monitoring of the aircraft physics.  The patented multi-stage algorithm will notify the pilot of a suspected engine failure almost instantaneously and light the suspect engine propellor knob to assist the pilot and confirm the correct engine in the event that a failure has occurred.

Will EngineSense give false failure indications in turbulence or uncoordinated flight?

The advanced patented EngineSense algorithm is intelligent enough to know the difference between turbulence/uncoordinated flight and a true engine failure.  With that said, if the pilot intentionally makes a dramatic power reduction on either engine then EngineSense will detect this as an engine failure and alert the pilot appropriately.

What is the size of the EngineSense unit?

The EngineSense primary unit is 3.5 inches wide and 1.8 inches tall.  This is approximately the same width as a standard business card and .2 inches shorter.  The unit is approximately .5 inches deep at the widest point.  The EngineSense replacement propeller knobs are the exact same width and length as the factory knobs and are slightly longer down the lever axis to accommodate the electronics.

What does the "test" button do?

Similar to the test button within most cockpits, the EngineSense test button will perform a series of failure indications and will light up the appropriate prop knobs ensuring a proper connection and battery.  This is recommended after installing the knobs to ensure proper right and left engine placement.  It is also recommended to press the test button before each flight.

Can EngineSense detect an engine failure in any phase of flight?

EngineSense technology focuses on detection at the most critical times the engine can fail.  While our flight testing has shown a very high degree of accuracy of detection during all phases of flight, it is possible that in reduced-power descents the aircraft motions resulting from an engine failure are too subtle for reliable detection of a failure.   As mentioned we have had great success in detecting these events but an engine failure during a reduced-power descent is the case which is most challenging for EngineSense.  Fortunately, a failure in this case is also the least likely to require immediate response

Does EngineSense have to be mounted in a certain place in the cockpit?

No, EngineSense can be mounted anywhere in the cockpit using the supplied 3M Dual Lock velcro but should be mounted aligned to the aircraft coordinate system.  Ideally, EngineSense is mounted in a visible location in the pilot’s field of view.  Given the small size and weight of EngineSense there are many mounting options to accommodate various cockpit layouts and location preferences.

What is the battery life of the EngineSense unit and the individual propeller knobs?

The battery life for the primary EngineSense unit is approximately 350 hours with the device powered on.  The propeller knob battery life is a little different since it has two main states, one while it is idle and not connected and another when it is connected to the main unit and the main unit is powered on. So assuming there is an on time of 100 hours the knob will last 360 days.

What kind of battery does the EngineSense unit and propeller knobs use?

The primary EngineSense unit uses two AAA batteries and the knobs use a small coin type battery.

How do I know when the batteries need to be changed?

The primary EngineSense unit has a green indicator light on the front of the unit during normal operation, when the battery gets to a low voltage indication the green light will turn yellow indicating the battery needs to be replaced.  For the propellor knobs the blue light on the front of the EngineSense unit will turn yellow indicating low battery in one of the knob units.

About Us

EngineSense is the result of an idea that started during my annual recurrent training at SimCom several years ago.  The basis of our multi-engine rating, checkride and annual recurrent training is all focused on dealing with an engine emergency.  Unfortunately there have been many NTSB reports that attribute the accident to the pilot either incorrectly feathering the good engine or getting distracted by trying to figure out and diagnose an engine problem.  

Using technology to address multi-engine safety and assist the pilot in an emergency made sense to me.  EngineSense is the result of over a year of research and development of the core patented algorithm all in the effort to increase safety.  While EngineSense can’t do the work for you, it can give you the confidence that the engine you have identified as the failed engine is the correct one.
