J.P. Instruments Fuel Scan 450

The Aviation Consumer, Product of the Year. JPI’s FS-450 is our top choice because it has all the options you need for fuel management.

JPI’s newest piece of panel wizardry relegates fuel-situation questions to relics of the past. From its new home between the top row of flight instruments and the top of avionics stack, the FS-450 blinked and winked the numbers to answer all my fuel-situation questions.

Connected to our Honeywell Skymap IIIC, the FS-450 happily winked and blinked its way through its information inventory and left me as relaxed as any fat-dumb-and-happy aviator should get — minus the “dumb” part of the equation, of course. Heavy-duty information and a light-duty price; could you want more? Sure, easy installation would be nice, something JPI also covered.

Fuel Used (USD):

How much fuel has been used since you last refueled. This number will always become larger as fuel is consumed. You can instead show the fuel used on a long multi-fuel stop flight and we will see later in this video how to do that.

Fuel remaining (REM):

How much total fuel remains in the aircraft. Only total fuel remaining in the aircraft is calculated.

Hours and minutes remaining (H.M.):

Based on the current fuel flow rate, displays the remaining endurance time. This parameter is most meaningful during cruise. During sea-level climb the fuel flow rate will be almost twice that of cruise and the endurance indication will be about half of actual. On the other hand, during a power reduction descent, the endurance will indicate more time than is actually available when flying at cruise power.

Fuel Required to Waypoint/ Destination (REQ):

This parameter will be displayed only if your EDM is receiving flight data from your GPS (this is a standard feature which is included with the Fuel Flow option). This will tell you how much fuel is required to get to the next waypoint or destination programmed on your GPS, based on your current fuel flow rate and present position.

Fuel Reserve (RES):

Fuel reserve when you arrive at your next waypoint. This parameter will be displayed only if your EDM is receiving flight data from your GPS (this is a standard feature which is included with the Fuel Flow option). This will tell you how much fuel reserve you can expect when you arrive at your next waypoint or destination programmed on your GPS, at the current fuel flow rate.

+ FAA TSO for Reliability and Accuracy, a 3 year warranty.
+ Talks to all GPS’s including Garmins 430/530 and all handheld’s etc. Displays gallons required to next waypoint or destination at no additional cost. FP-5L does not report “gallons to destination”. FP-5L does not work with a “handheld” GPS.
+ Programmable display for Gallons, Pounds, Liters. No imperial gallons .
+ Remote “Warning Light” programmable with Low fuel and low time warning.
+ Automatically calculates K- factor for excellent 1% accuracy
+ Return line systems (Pressure Carburetor) and gravity flow, no problem.
+ Clock size, 1.5″ deep, 2 1/4″ hole, 5.0 oz. wt.,
Transducer 3 oz. wt.

• TSO’d for use in turbo-prop aircraft.
+ When your, El, Hoskins, or Shadin fails upgrade it to destination an FS-450 using old transducer.
+ Automatic reminder (flashing digits) to update Fuel added. Fuel added Can be set after take-off not possible with the FP-5L/FP-5
+ “USED” Total fuel used can be set to zero at any time during flight.
+ Twin and Single FS-450M instrument.
+ %HP Calculated on fuel burn.
+ Timer included

My FS 450 is so useful in my Cessna 152 that I have been a huge promoter of your product. I wish all Cessna’s would come factory equipped with your gages. Great instrument!

“This is my third J.P. Instruments, FS-450 that I have installed in aircraft I have owned. I will not own an aircraft without one. It’s much more accurate than mechanical gauges.”

The FS450 is an excellent product! I have it in my 172 in the original analog clock position. LEDs are bright and easy to read in that lower left panel position. Prior to installing the unit I used a default fuel flow of 8.0 gal per hour for all my flight planning. The FS450 confirmed this worst case flow rate at high throttle setting in the low to 5000 MSL altitudes. The benefit of the FS 450 is the choice to burn gas to get somewhere or to really see what the time versus cost trade off is for economy (6.8 – 7.2 gal) or loiter (6.5 or less) power settings. I also get real time accurate values at high altitude cruise (10,000+ MSL) versus just using the fuel usage projection charts from the Cessna POH. The POH values are good but the FS 450 gives me all the data including climb, cruise and decent to maintain true fuel awareness and safety. I have a Garmin Aera 550 connected to the FS 450 to obtain next way-point information (fuel required & fuel reserve).

I got the FS 450 but I haven’t be able to installed… my mechanic said he needs the hoses and the fittings to complete the installation… QUESTION… Where can I get the hoses and the fittings for my cessna 182?
Thanks
