Falken EMS

Safety and Performance for Your Aircraft

FAA approved for Installation in certified and experimental aircraft.


Advanced Engine Monitoring

The Falken EMS is a stand-alone version of the EMS included with our FlightView EFIS. It supports full instrumentation for engines up to 8 cylinders and monitors over 30 engine parameters displayed on an Apple iPad or iPhone.

Falken EMS App

The free Falken EMS app displays up to 36 parameters, records detailed engine logs in the industry-standard CSV format, and includes a live temperature trend display. The peak finder function simplifies adjusting the mixture for rich-of-peak or lean-of-peak operations.

The app can run stand-alone or in split-view mode on iPad, sharing the screen with an EFB application.

Engine Logging: Records engine performance data in industry standard CSV format, compatible with popular analysis software and websites.

EGT Peak-Finder: Helps pilots adjust the fuel mixture for optimal fuel efficiency.

EGT and CHT Trend View: Records exhaust gas temperature (EGT) and cylinder head temperature (CHT) readings on a time-sequence graph, allowing pilots to easily note any departures from the nominal operation.

Customizable Display: Enables users to tailor the app layout with assigning gauges, annunciators, and text indicators.

Split-view Layout: Supports split-view on iPads, allowing simultaneous use with other flight apps.

Customizable Limits: Allows users to set caution and warning alert points which correspond to color shifts (green = nominal, yellow = caution, red = warning) for immediate feedback.

Fuel Totalizer: Tracks fuel consumption over time, serving as a backup to the fuel level gauge.

Engine Power: Calculates the percentage of rated power being generated by the engine, specific to Lycoming and Continental engines.

Audio Alerts: Provides important notifications through the iOS device’s audio output (often tied to the pilot’s headset using Bluetooth).


Monitored parameters include:

  • RPM
  • Manifold Pressure
  • Exhaust Gas Temperature
  • Cylinder Head Temperature
  • Oil Temperature
  • Oil Pressure
  • Fuel Level
  • Fuel Pressure
  • Fuel Flow
  • Voltage
  • Amperage
  • Hobbs Time / Tach Time
  • Carburetor Temperature
  • Coolant Temperature
  • Gearbox Temperature
  • Turbine Inlet Temperature
  • Outside Air Temperature
  • Flap and Trim Tab Position

The system includes a total of 29 inputs:

  • 16 thermocouple inputs for EGT, CHT, TIT, OAT, etc.
  • 8 analog inputs for pressure, fuel level, flap/trim position, etc.
  • 2 tach inputs for engine speed
  • 2 fuel flow inputs
  • 1 amperage shunt input

Data collected by the EMS is relayed to the display and logging system over a Bluetooth wireless link when operating stand-alone (not integrated with an EFIS). 

Sensor connections used reliable industrial spring-clip connectors to simplify the installation process. Rather than building a complicated wiring harness, probe leads connect directly to the spring-clips.

Falken EMS also includes RS-232 and CAN bus connectivity for hard-wired connectivity to other avionic systems. In an experimental aircraft, Falken EMS can interface with Falken’s FlightView EFIS, allowing owners to 

upgrade one step at a time. In certified aircraft, Falken EMS can be tied into Falken’s FlightBox Pro NORSEE ADS-B receiver. 

Engine probes and senders are sold separately, allowing the aircraft owner to select the optimal set of interfaces for their aircraft.
