MAIN SCREEN

RPM

The RPM is displayed in large, bright, crisp digits as well as in a 270 degree graphic arc, so you can simultaneously monitor RPM at a glance and with precision accuracy. Wires from the MVP-50P harness connect to the back of the aircraft ignition switch and pick up the signals from the magnetos. The MVP-50 provides lightening quick RPM response while maintaining rock solid stability.

Manifold Pressure

Like the RPM, the Manifold Pressure is displayed in large, bright, crisp digits as well as in a 270 degree graphic arc. You will be able to dial in your Manifold Pressure with precision when flying with the MVP-50.

Outside Air Temp

The MVP-50P simultaneously displays Outside Air Temperature in Celcius and Fahrenheit, meaning you don't have to do in flight conversions or switch between the two. Ice Zone warnings can be set to alert you when temperatures reach ranges within which ice can form.

Engine Temperatures

EGT and CHT are always shown for each cylinder, whether in Bar Graph or Digital Mode. Temperatures have a stable, one degree resolution for accurate leaning and engine diagnostics. Both EGT and CHT differentials, as well as the hottest cylinders, are always displayed for quick reference.

Fuel Flow

The main screen constantly displays the current fuel flow, accurate to .1 gph. Proprietary algorithms allow rapid response to engine adjustments without irritating, jumpy readings.

Fuel Levels

Up to four fuel levels at a time may be monitored and displayed on the Main Screen at one time.

Electrical System

The precise resolution of .1 volts and .1 amps allows you to accurately monitor and manage the load on your aircraft electrical system and the health of your battery.

Timers

Select from Up Timers, Down Timers, Flight Time and Clocks.

The Bar Graph

The MVP-50P comes complete with a full engine analyzer. The MVP-50P bar graph displays EGT & CHT, has programmable redlines for each cylinder, displays temperature differentials, assists with leaning for ROP and LOP operations, and has an easliy resettable Normalized Mode with long-term memory for engine trend analysis.

Redlines & Operating Range

Regardless of the parameter you monitor with the MVP-50P, the operating ranges are completely programmable. The MVP-50 will alert you via visual and/or audible alarms when a parameter exceeds the programmed limits.

Choose Your Functions

Several different functions are available, including Gyro Vacuum, Flaps, Hydraulic Pressure, Pressure Altitude, Airspeed, virtually any temp or pressure, plus more! Or, add an additional voltage or amps to monitor a secondary bus. The MVP-50 even allows you to create and name your own functions. The options are nearly limitless.

THE BAR GRAPH

Overview

The MVP-50 boasts a fully functional bar graph, complete with ROP and LOP leaning modes, a Normalized Mode, state-of-the-art “peak markers” and separate programmable limits for each cylinder’s CHT and EGT to alert the pilot of any engine trouble.

ROP Mode

The Rich-of-Peak mode on the MVP-50 informs the pilot when the first cylinder peaks, as well as how many degrees below peak the engine is operating.

LOP Mode

For Lean-of-Peak Operations, the MVP-50 informs the pilot as each cylinder peaks, at what temp each peaks, and how far from peak each is. For quick reference, every cylinder’s peak information is constantly displayed and “tattletale bars” are shown above each cylinder, indicating where each cylinder peaked the last time the engine was leaned.

Normalized Mode

The Bar Graph can easily be “Normalized,” creating a baseline from which to monitor in-flight engine temperature changes. When Normalized, all of the bars start off at the same height. If any cylinder's column is not the same height as the others, than that cylinder's Exhaust Gas Temperature has changed in relation to the other cylinders. These changes can be critical indicators to problems occuring within your engine.

Peak Markers

While other monitors don't maintain your engine's leaning history, The MVP-50's Bar Graph keeps track of exactly where the cylinders peaked during each leaning process. When leaning, the MVP-50 displays a peak marker indicating where each cylinder peaked during the last leaning process, providing visual assistance to pilots.

DATA RECORDING

Overview

The MVP-50 records each flight, which allows you to perform post-flight analysis on the engine and system parameters of your aircraft. When you decide to review the flights, simply download them via the USB port and upload them to your computer. Either view them in EGView, or look at the numbers in a number-crunching program such as Excel.

Flight Logs

Each flight has a Flight Log assigned to it, which contains the flight in its entirety. The MVP-50P permits you to adjust how often data is stored, so it is possible to record parameters as often as three times per second to as little as once per six minutes. Each Flight Log is also time and date stamped for easy identification, so you don't need to remember which flight is which when scrolling through your Flight Log history.

Min/Max Logs

If you don't want to analyze an entire flight, simply review the minimum and maximum flight logs stored in the MVP-50P. These logs are a simple history of the maximum and minimum parameters reached during specific flights. These logs are stamped with the same flight number as their corresponding flight log, so if you decide to analyze the entire flight, you can easily identify it by its number.

FUEL MANAGEMENT

Overview

With the MVP-50, you will never again have to guess as to your fuel-on-board status. The MVP-50 keeps track of Fuel Flow, Fuel Remaining, Time to Empty, up to four Fuel Levels, Fuel to Waypoint, Fuel in Reserve once your next waypoint is reached, Miles per Gallon, Fuel Used since your last fill up and Fuel Used for each flight. Though Fuel Flow is accurate to .1 gallon, pilots may choose to display fuel in Gallons, British Gallons, Liters or Pounds.

Fuel Flow

The MVP-50 boasts accurate, stable fuel flow to .1 gph. While other fuel flows either have quick response with nonstable readings, or stable readings with sluggish response, proprietary algorithms allow the MVP-50's fuel flow rapid response to engine adjustments without irritating, jumpy readings.

Fuel Remaining

The MVP-50 not only displays Fuel Level, it also displays a "calculated" Fuel Remaining. This Fuel Remaining is based on the factors of time and your Fuel Flow. For example, if you start with 40 gallons on board and have flown for one hour at 10 gph, you will have 30 gallons remaining. Providing the pilot resets the fuel level when the tanks are refilled, this function is an extremely accurate and powerful tool to assist you with fuel management.

Time to Empty

The MVP-50 automatically determines how much time is remaining before the tanks run dry. This function is calculated on current Fuel Flow and Fuel Remaining. The MVP-50 will alert you when the Time to Empty reaches a pilot-programmable limit.

Fuel Levels

Up to four fuel levels at a time may be monitored and displayed on the MVP-50. Though Fuel Levels are accurate to .1 gallon, pilots may choose to display fuel in Gallons, British Gallons, Liters or Pounds.

Fuel to Waypoint

The MVP-50 not only receives information from an Electronics International flow transducer to provide you with pinpoint fuel flow accuracy, it also receives GPS information. By combining GPS information with the flow transducer output, the MVP-50 is capable of providing pilots with how much fuel is needed to reach the next waypoint.

Miles per Gallon

Another feature the MVP-50 derives from Fuel Flow and GPS information is Miles per Gallon. You will be able to immediately determine the best fuel economy for your flight, while in the air. Pilots can switch between Statute Miles per Gallon and Nautical Miles per Gallon.

Fuel Used

The MVP-50 keeps track of how much fuel has been used during each flight, as well as how much fuel has been used since the last time the tanks have been filled. Having such an accurate fuel used history will allow you to more accurately plan for cross-country flight fuel stops.

Electronics International has had great sales success with its large-screen engine monitor, the MVP50. In this video, AVweb's Paul Bertorelli takes a test flight with Sarasota Avionics' Kirk Fryar to see how it works.
