Official specs of airplane not matching with infnite flight airplane!

Here is my question and I don’t know if it’s an explanation for this… Lol.
I fly the Cessna citation X from Los Angeles to London… which is over 5437 miles , on the official website of Cessna citation there is said that the flight range of the Cessna citation X is 3701 Miles…
So almost 2000 miles extra on infinite flight… , isn’t that great 😂
Cruising altitude I chose was 30000 ft,
Ground speed 567 knot’s
Airspeed if I remember well was around 300 knot’s.

all these numbers that I used to fly the Cessna citation X from Los Angeles to London do not match with the official spec’s of that particular aircraft, totally unrelated results between infinite flight Cessna citation X and the real Cessna citation X.


Make sure to consider that when you get into the jet stream to London, you’ll get quite the good tailwind when crossing the Atlantic.


Mate, there are many factors influencing the flight. The two main factors today probably were speed and winds. Of course, the Citation is a bit outdated, however please consider that flight testing in real life differs from flying across the Atlantic, where jet streams can severely influence your fuel flow.

And reading your post again, just compare the airspeed with the ground speed:

So, this means higher winds made you fly faster and more efficiently. End of story.

And the jet stream over America

Influence the fuel Flow by 2000 Miles extra ? 😄
I understand the Jet stream and all had a tail wind but never over 50 knot’s tail wind on that particular flight , actually it was not a pure tail wind but more a 200 degrees wind , south west to northeast direction.


Sure. Your airspeed and groundspeed reports are comparable with your fuel consumption.

The fact that you chose a lower airspeed also helped save fuel.

And by the way, I am speaking from experience and with common sense.

I don’t know about a lower airspeed… at 30000 ft you couldn’t go past 300 knot’s airspeed because you’d get a violation for over-speeding probably not more than 345 knot’s airspeed which is the maximum allowed airspeed on most civilian Jets, and the engine RPMs were over 85%… so I don’t know bro , it looked really inaccurate to me.


The CCX range is broken, that’s just because it’s an older aircraft and hasn’t been reworked yet. Some say its almost 3x the normal range.


Correct, it’s incorrect. Ignore the other bonkers suggestions!


@Arian_Gjata I’ve flown the CCX in IF from Los Angeles to Singapore. The Cessna Website is in Nautical miles, so you’ll need to convert it. The CCX can make that flight, but you’ll need to fly way higher that FL300. Private/Business jets like to fly high. I’d fly at FL410 for that flight. Cruise speed is M 0.83 - M0.87

Aircraft like the CCX and gulf stream go transatlantic, so consider we might have the ER

Please tone it down. There is no need for that attitude :)

That’s incorrect. The fuel flow will remain the same because the autopilot is set to keep airspeed and not groundspeed. Since jet streams do not affect airspeed but groundspeed, the fuel flow will remain the same regardless of how much tailwinds/headwinds you get during your flight.

@Arian_Gjata, some of the numbers for the CCX are indeed off in Infinite Flight compared to real-life. This is because the model of the aircraft is relatively old, and the quality to which aircraft were made back then was not as high as the expectations we set for the developers today.

So, at this point in time, you can enjoy flying an extra 2,000 miles in this aircraft before it eventually gets a rework. :)
