If I'm flying someplace just outside of 3 hrs range, I'd probably do some better calculations, but that hasn't come up since I've been flying. There's probably a way to use the tables to find an equation for each aircraft, but damned if I know how to do that. When did organ music become associated with baseball? Usually this is some extra fuel that the aircraft commander decides to load because of particular circumstances.

How much does does a 100 dollar roblox gift card get you in robhx? So what I want to know, how do you properly calculate, by the book, the fuel needed for a flight, based on distance, climb rate, speed, windspeed, meteorological conditions, fuel mixture, and all that stuff, so I could implement it in my code. User inputs would be tail number, pressure, temperature, power setting, etc.
... meaning that I want to make/build/code a fuel calculator for a Cessna 172 flight. Here’s the flight data from A to B, alternate C. Climb and descent fuel flows are negligible (in this case) as the higher fuel flow during climb is averaged by the lower fuel flow during descent. It depends entirely on the aircraft, type of fuel, how much fuel and where you are in the world. This community is for discussion among pilots, students, instructors and aviation professionals.

Hello, flightsimmer and wannabe aviator here. The CESSNA 172SP, manufactured from 1998 - to present, requires a 1 person crew and can transport up to 3 passengers.

Let’s do a quick example. Always consider the airport from which you’re taking off. Who is the longest reigning WWE Champion of all time? ), Same thing for the Alternate Fuel: 50NM/120Knots = 0,42Hr => 15USG/Hr * 0,42Hr = 6,3USG.

Once I figured out what I needed to do, I completed a couple of operations (take off distance and accelerate-stop) and then was stuck by the oppressive tedium of what I was doing and I quit. Why don't libraries smell like bookstores? From the trip time and the cruise fuel consumption we get the Trip Fuel: 15USG/Hr * 2,5Hr = 37,5USG. , How To: calculate the fuel required for your flight, The Reality Expansion Pack update v2.2 is available, The Reality Expansion Pack for the V35B Bonanza has been released, Together with JRollon Planes for the SIAI-Marchetti SF-260D, Update: REP 4.5.4 for Piper Arrow, Turbo Arrow and the SF.260, Release: Reality Expansion Pack for JustFlight Piper Turbo Arrow, Release: Reality Expansion Pack for JustFlight Piper Arrow III, Of an individual aircraft from the expected fuel consumption data, 5 minutes of flight at holding speed at 1500ft, No Alternate: your destination is an isolated aerodrome. GS = 130 – 10 = 120Knots, Now we can calculate the trip time: 300NM / 120Knots = 2,5 hours (or 2:30, in a more convenient format).
You shall calculate it using the same rules applied to Trip Fuel. data includes full 6 qts. No Enroute Alternate and Inability to Hold Height: you’re long way from home and a malfunction does not allow you to fly at altitude, thus causing higher fuel consumption. That is, the total amount of fuel to have in the tanks when your airplane still sits on the apron. Now let’s get the Contingency Fuel (5% of the trip): 37,5 * 0,05 = 1,875USG (~ 2USG, be conservative!
Cessnas are pretty good planes for this because they give tabulated fuel burn numbers in the POH which means you can put those tabulated values into an excel spreadsheet and have excel interpolate for the ambient conditions on the day of the flight. I rent wet, so I usually run at 'full rental power." Press J to jump to the feed. I could calculate with more precision, but I find it easier to ballpark it on the safe side.
