SkyView - Dynon Avionics

SV-EMS-220 Installation and ConfigurationTo find and configure the pulses/gallon value associated with your fuel flow transducer:If you have the Floscan 201B (Dynon P/N 100403-001), this number can be found on the tagthat came with the transducer. The pulses/gallon value for transducer is 10 times the numbershown after the dash. So, if your transducer had the tag that is labeled “16-2959”, you wouldenter a pulses/gallon value of 29590 in the pulses/gallon section of the fuel flow sensor setupmenu. If you have lost your tag, a starting pulses/gallon of 30000 will be close enough to beginusing the function.If you have the EI FT-60 “Red Cube” (Dynon P/N 100403-003), enter a starting K-VALUE of68000.Over time, you may notice that the instrument’s computation of gallons or liters remaining(based on fuel flow) is either high or low. This is a result of many factors, including individualinstallation. To correct for this, follow this procedure:Over several fill-ups keep a running total of the amount of fuel added. Keep a running total ofthe GALS (or LTRS) USED parameter over this same time span.Perform the following calculation:FuelUsed ( computed )FuelFilled ( actual )close to 1. We’ll call this number, FuelFlowRatio.. You should obtain a number that isNow perform this calculation: CurrentPulsesPerGallon*FuelFlowRatio. Enter this number asyour new pulses/gallon value.Observe the results over your next tank for accuracy. Repeat the above if necessary.The general rule of thumb: if your GALS (or LTRS) USED reads higher than you expect, increasethe pulses/gallon; if it reads lower than you expect, decrease the pulses/gallon.If your engine has a return fuel flow sensor, note that there is a second pulses/gallon settingthat is mapped to a second set of input pins. When a second fuel flow sensor is connected andthe pulses/gallon is adequately set, the fuel seen returning through the second fuel flow sensoris automatically subtracted from the flow that is seen through the primary sensor. If you do nothave a second fuel flow sensor, you may ignore this setting entirely.Fuel Computer PresetsFuel Computer computations are based on measured fuel flow and the pilot’s input of theaircraft’s starting fuel state. SkyView offers a few settings that allow the pilot to pre-programfull fuel and an optional second “preset” fuel quantity. Once programmed, typical aircraft fuelloads are then quickly recalled under in the EMS > FUEL menu as described in the Pilots UserGuide.There are three fuel computer options, found under SYSTEM SETUP > SYSTEM SETUP >AIRCRAFT INFORMATION. They are only applicable if you have a fuel flow sensor installed:Total Fuel Capacity–set this to the total usable fuel on board when the tanks are full.Once this is set, the pilot is prevented from accidentally setting more than this amountof fuel on board.7-46 SkyView System Installation Guide - Revision J
