Introduction 1.1 Features: 1.2 Overview of the MVP Screens: 1.3 System Hardware: 1.4 SELECT Knob and Button Operation: 1.5 Display Dimming: 1.6 Cleaning the Screen: 3 1.
1.1 Features: The MVP-50T is a state-of-the-art Glass Panel Engine Monitor that provides most of the engine and system instruments and annunciator found in an aircraft panel. Each of the instruments displayed on the MVP’s Main Engine Screen provides features not found in most multifunctional displays or traditional gauges. Aircraft panels equipped with individual instruments require a pilot to scan and interpret a multitude of gauges spread across an entire panel.
If any function on the Main or System Screen goes into the red or yellow, the appropriate annunciator will blink, the external warning light will blink and an appropriate voice warning will be played. In this way the pilot is immediately alerted of a potential problem and should view the appropriate screen for further information. Setup and Control Screen Menu (see section 5.
The MVP hardware consists of the following three groups of components: A. Probes, Transducers and Extension Cables – These components are used to measure pressures, temperatures, fuel flow, volts, amps, fuel levels and many other engine and aircraft system functions. The analog signals produced by the transducers and probes are routed through the Extension Cables to various EDC inputs. B. EDC (Engine Data Converter) – The EDC converts the analog signals from the probes and transducers to a digital format.
1.5 Display Dimming: The MVP provides two methods of controlling the brightness of the TFT display. When the “Brightness Control” is set for “Auto Dimming” the display will automatically dim as the ambient light reduces. The light sensor is located next to the USB port on the MVP front panel. When the “Brightness Control” is set for “External” an external control pot can be used to control the brightness of the MVP display.
Main Engine Screen 2.1 Power-up Add Fuel Message: 2.2 Main Screen Layout: 2.3 Arc Gauges: 2.4 Vertical Strip Gauges: 2.5 Annunciators (CAS): 2.6 Digital Instruments: 2.7 External Master Caution and Warning Lights: 2.8 Voice Alarm Control Panel (Experimental Only): 2.9 Disabling a Display: 8 2.
The Main Engine Screen provides the aircraft system and engine instruments you will view most frequently during a flight. There is important information published in the Important Notice section (found in the front of this manual) that must be read before operating this instrument. Please read the Important Notice section at this time. 2.1 Power-up Add Fuel Message: An add fuel message located in the lower center section of the screen will appear when the MVP is powered up.
2.3 Arc Gauges: The Arc Gauges incorporate a digital readout and an analog arc. The color of the digital readout will reflect the current operating level of the instrument (i.e., if the N1 is operating in the red, the digital readout will be red). The digital display can be set to blink when a functions operating level reaches a yellow and/or red operating range. To stop the blinking, push any button, or rotate the SELECT knob.
At the top of the Main Engine Screen are three rows of annunciators. These annunciators makeup a Crew Alert System (CAS). The top two rows of annunciators are defined by the installer. The bottom row of annunciators is associated with functions displayed on the Main Engine Screen. Also, at the far right of the bottom row is a “System” annunciator. If any function found on the System Screen goes into the red or yellow, the “System” annunciator will blink in the appropriate color.
The “4. Redlines, Limits and Color Setup” screen and the “Serial Port & External Warning Light Setup” screen provides fields to set the operation of the Caution and Warning lights. Changes in these screens are password protected. As with any warning system, it is important that there are no false alarms. False alarms can desensitize a pilot to all alarms, which can cause a serious situation to go undetected. Setting proper red and yellow limits for each function is a key step in eliminating false alarms.
Panel switch to the “OFF” position. When the Control Panel Switch is once again set to the “ON” position, the MVP will announce “Voice Annunciator enabled.” This will be followed by the announcement of any active alarms. Adjusting the Volume of the Voice Warnings: The “Voice & Display Controls” screen provides a control to adjust the volume level of the voice warnings.
System Screen 3.1 Trim Indicator: 3.2 Flap Indicator: 3.3 Gear Position Indicator: 3.4 Gear Up Warning: 3.5 Engine and System Functions: 3.6 Annunciators (CAS): 3.7 Five Digital Instruments from the Main Screen: 16 3.
The System Screen is intended to display system functions and the configuration of the aircraft. This gives the pilot one location (i.e., one screen) to find all of the pertinent system functions and configuration information on the aircraft. Normally these functions would not need to be displayed continuously. The following features in the System Screen are provided: 3.
3.4 Gear Up Warning: The MVP can provide a gear up voice warning if the following functions are monitored: Gear Position, N1 and Airspeed. As you enter the pattern and reduce N1 the aircraft’s Airspeed will start dropping. If N1 and Airspeed drop below a programmed level (set for your aircraft) and the Landing Gear is not down and locked, you will get a voice warning. This method allows you to perform low power, fast descents and high power, low speed climbs without annoying warnings.
Flight Data Screens 4.1 “Help” Screen: 4.2 System Screen: 4.3 “Add Fuel” Screen: 4.4 “Fuel Management” Screen: 4.5 “Timer” Screen:*** 4.6 “Clock and Hour Meters” Screen: 4.7 “Weight and Balance” Screen: 4.8 “Checklist” Screens: 4.9 “Flight Notes” Screens: 4.10 “Gen.

A menu of the Flight Data Screens may be found by pressing the “Menu” button when displaying the Main Engine Screen. When the Flight Data Screen Menu or any Flight Data Screen is being displayed all annunciators and five Main Engine Screen functions will be displayed to the right of the Flight Data Screen. The operation of each Flight Data Screen is described below. 4.1 “Help” Screen: The Help screen provides an overview of the MVP operation.
the K Factor. The K Factor is a measurement of the pulses per gallon that the flow transducer outputs. Due to variations in the installation of the flow transducer, it may be necessary to adjust the K Factor for the first few flights in order to get an accurate fuel remaining, fuel used and flow reading. The K Factor should be changed only when the fuel tanks have been filled accurately on level ground.
4.4 “Fuel Management” Screen: The “Fuel Management” screen is divided into the following four sections: 4.4.1 Fuel Level Data: This section displays the fuel levels measured in each of the tanks. The total fuel onboard is displayed at the bottom of this section. The accuracy is only as good as the fuel sensors and the calibration of the MVP to each tank. 4.4.2 Fuel Flow Data: This section displays fuel data based on fuel flow and is calibrated with the K Factor. The following data is provided: F.
“Dist. Reserve:” Distance you can fly beyond your Way Point based on current Distance to Empty and Distance to Way Point. If the Time Reserve drops below 45 minutes, this value will be displayed in Yellow. If the Time Reserve drops below 30 minutes, this value will be displayed in Red. 4.5 “Timers” Screen: The “Timers” screen provides the following timers: “Up Timer:” An Up Timer is provided with a recurring alarm. If the alarm is set for 30 minutes, you will get an alarm every 30 minutes (i.e.
The “# Cycles” can be setup to count airframe (takeoff / landing) cycles or engine start cycles. The value of “# Cycles” is based N1. When a preset high value of N1 is reached the “Status” field will display “Armed.” Then, when a preset low value of N1 is reached the “Status” field will display nothing and the value of “# Cycles” will be incremented by one.
What makes the MVP’s Checklists so powerful is the fact that they are interactive. Next to each item is a “check” box. The Select knob allows you to enter an “X” in the box next to each item, or remove an “X” from a box if one is already there. Putting an “X” into a box will move the arrow to the next box. You may choose to skip any item in the Checklist by simply rotating the Select knob past the item. The MVP will always remembers your last place in the Checklist.
The MVP will always remember which portion of the Flight Plan screen was last viewed. You can leave in the middle of a Flight Plan screen to look at other screens and when you return you will be at the same place in the Flight Plan screen as when you left.
Creating a General Info File: A custom Gen Info File may be created in Word, WordPad, Notepad or most any text editor. See “Creating a Checklist, Flight Plan or General Information File” in the Appendix section of this manual.
Setup and Control Screens 5.1 “USB and Data Recording” Screen: 5.2 “Voice Warning Control” Section: 5.3 “Screens Button Setup” Screen: 5.4 “System Configuration Screens Menu:” 30 5.
The “Setup and Control Screens Menu” section lists those screens you will most often use to change data during flight. To view the available Setup and Control Screens press the Menu button when displaying the Main Engine Screen. Then scroll to the lower section of the blue screen. The following describes the operation for each Setup and Control Screen. 5.1 “USB and Data Recording” Screen: This screen allows the MVP to read Checklists, Flight Plans and General Info files from the USB Data Stick.
Note: If you enter a system configuration screen and change any data, a new flight data file with a new flight number may be started. Note: Formatting information on recorded flight data can be found in the Appendix under the heading, “Recorded Flight Data Formatting.” 5.1.3 “Data Recording Setup” Section: “Recording Interval”: The time between recordings can be set from 0.3 seconds to 10 seconds.
5.2.4 “Button Controls” Section: The MVP has three Aux Digital Inputs that may be used to remotely control the Select knob, Exit button and Screen button. 5.3 “Screens Button Setup” Screen: The Screens button (found on the front of the MVP) provides a quick way to switch between the screens you use most often. Place an “X” in the box for each screen you would like displayed when you push the Screens button. The fewer screens selected the more convenient the SCREENS button operation will be. 5.
System Configuration Screens 6.1 Password Protection: 6.1.1 Level #1 Password (Maintenance): 6.1.2 Level #2 Password (OEM): 6.2 System Configuration Screens Overview: 6.3 “USB Flight Data File Manager” Screen: 6.4 “USB Config and Software Program Manager” Screen: 6.5 “Change Password” Screen: 6.6 “Aircraft ID, Gear Warning and TAS Setup” Screen: 6.7 “Engine Data, Hour Meters and Flight Timers Setup” Screen: 6.8 “Serial Port Setup” Screen: 6.9 “Weight & Balance Setup” Screen: 6.
6.1 Password Protection: The MVP provides a number of screens for the pilot to use during flight, none of which require a password. It also provides many System Configuration Screens that are used to configure the MVP for a specific aircraft. Some of the aircraft functions (fuel level, flaps, trim, weight and balance, etc.) must be calibrated during installation and some must be set at the factory or by an OEM. The MVP provides two levels of passwords for configuring and calibrating the unit.
6.2 System Configuration Screens Overview: The System Configuration Screens provide access to setup and calibration data. By accessing this data you can properly set up the MVP to work with your aircraft. It is important you understand the operation of each screen and function before you change any data. If you do not have the knowledge to properly change an item, seek help. All changes must be verified that they provide proper MVP operation.
“Write Files to USB Data Stick” Section: “Write All Checklists and Text Files”: This line allows you to write all the Checklists, Flight Plans and General Information to the USB Data Stick. All of the files will have a “.txt” extension and will be stored in the following directories on the USB Data Stick: Checklists ------- “checklists” directory. Flight Plans ----- “flight_plans” directory.
The “Retrieve ALL Backup Config Files” command reads all the stored configuration data on the USB Data Stick. If the configuration data was NOT stored to the USB Data Stick by same MVP that is retrieving it, the command will fail and an appropriate message will be displayed. Each MVP system has the following unique calibration data that should not be shared with other MVP systems: A. Temp Comp Diode offset (this diode is located on the middle connector of the EDC). B.
Once the MVP has been configured for your aircraft the password should be set to a unique number to limit access to the configuration data. Do not lose your password! Without the correct password you will not be able to access the configuration data. If you do lose your password, contact Electronics International Inc. for help in retrieving it. 6.6 “Aircraft ID, Gear Warning and TAS Setup” Screen: “Aircraft ID:” The aircraft number shown here will be used in the header of the recorded data.
“One Cycle = N1 above _____% then below _____%”: This line allows you to set the logic to determine when a cycle is counted (engine or flight). An engine cycle is counted for each engine start. To record engine cycles, set the “N1 above” field to a value just above the maximum N1 that can be reached during start with no fuel (around 35%). Set the “then below” field to a very low value (around 3%). A flight cycle is counted at each takeoff.
If the MVP cannot find a valid GPS signal, the Port 2 Receive Status field will switch (every six seconds) between “Trying 9600” and “Trying 4800.” If the MVP cannot find a valid GPS signal or the MVP is not connected to a GPS, the Port 2 Receive field should be set to “Disabled.” The Tx port will not transmit when the Receive Port is “Trying.” “Port 2 TX Format (Out)”: This field sets the format of the transmitted signal on Port 2 output.
6.9 “Weight & Balance Setup” Screen: The data in this screen configures the “Weight and Balance” screen (found in the “Flight Data Screens Menu” section of this manual) for your aircraft. It is imperative that the correct CG limit data is set up in this screen. CG data can be found in your aircraft’s POH. The data used in this screen is CG Limit Data (not moment data). The four graph points define the chart used in the “Weight and Balance” screen.
The tanks must be calibrated with the wings level and the aircraft set for level flight pitch. Start with the tanks empty. “Fuel Tank”: This field selects the fuel tank to be calibrated. You can switch between tanks any time during the calibration cycle. Note: The tanks must be calibrated in US gallons. However, fuel levels may be displayed in other units by changing the “Display Units” field in the “3. Redlines, Limits and Color Setup” screen (found in the “3. Redlines, Limits and Color Setup” screen.
6.12 “Flaps, Trim and Special Function Calibration” Screen: This screen allows you to calibrate Flaps, Trims and special functions. A voltage signal is received from a control pot connected to the flaps (or trim tab). The value of this signal is called “Raw Counts.” The Raw Counts should change as the flap position changes. To scale these Raw Counts to a meaningful value perform the following: “1. Select the function and its voltage source.” “Function”: Select the function to be calibrated.
6.14 “EDC Inputs, Functions and Screen Setup” Section: Probes and transducers are mechanically connected to the aircraft and are electrically connected to the EDC (Engine Data Converter). The EDC converts the analog signals from the probes to digital signals and then transmits them to the MVP. The following screens allow you to display a function on an MVP screen and set the redlines and limits.
The “Reading” column at the far right of the screen shows the current reading for each EDC Input. This can be used to troubleshooting a channel (e.g., you can heat a temperature probe or apply pressure to a pressure transducer and see which EDC Input responds). If a probe listed in the “Probe” column is shown in yellow, the calibration of the EDC Input for that probe has been changed from factory default. EDC Input calibration can only be changed in screen #5.
6.18 “4. Redlines, Limits and Color Setup” Screen: This screen allows you to program up to five Color Ranges for any Function. “Function:” This field allows you to select which Function will be programmed. “Display Name:” This field allows you to change the name of the Function shown in the display. “Display Units:” For most Functions you may select the units in which the Function will be displayed on the Main Engine Instrument Screen.
“Voice Warning File”: This line sets the voice file that will be played when a red and/or yellow warning is reached (as determined by the “Red & Yellow Ext Warning Logic” setting). 6.19 “5. EDC Input Calibration” Screen: Warning: This screen is for advanced use only and data in this screen normally should not be changed. This screen allows you to change the calibration parameters of an EDC Input used for a specific Probe and Function.
“Reference:” The Interim Value may be referenced to another Function. The value of the Function selected in this field will be added (+) or subtracted (-) from the Interim Value. Differential measurements can be made by subtracting one Function from another. Temperature measurements based on thermocouple probes must be temperature compensated by referencing the “T. COMP” (temperature compensation) Function. “Allow Negative Readings:” Negative readings should not be allowed on functions such as RPM, M.P.
