Questions about the ranges of A333 and B77W

[Richard330]

Dear the team of of Infinite Flight,
I’m a fan of Infinite flight over ten years. Recntly I noticed a problem related o the ranges of Airbus A330-300 and Boeing 777-300er, those are my most favorable models. In the live mode, a A330-300 can easily fly from New York city to Hong Kong, the distance is about 13000km. The actual range of an A333 is about 12000km, but in Infinite Flight it is over 15000km. However, a Boeing 777-300er is hardly to fly from New York city to Seoul, the distance is about 11000km. In the real world, a B77W has a range of about 15000 km. Please help me to check if there are some setting which are nit accurate in the system. Thank you.

Regards,
Richard

Welcome to the community @Richard330!

Range can be affected by a wide array of factors. These include winds (tailwinds add to range, headwinds subtract), cruise speed (the faster the more fuel you burn), altitude and weight (if you’re too heavy for a specific level you will burn more fuel).

The physics in Infinite Flight are not spot-on with the real world, so there will almost certainly be disparities between the performance of a plane on IF compared to irl.

I don’t believe this is a bug with your device itself. I think it’s down to simply the physics engine itself.

Hopefully I helped you out. It’s also really cool to hear how long you’ve been with the game, you’re truly a veteran. Have a good one!

Yes if you are empty. Well the A333 can also do that route in real life if only carrying fuel, in IF also. But when you start adding payload, your range decreases.

@Richard330

The actual range of an A333 is about 12000km

You would be surprised. With full pax and some cargo, it will definitely struggle to even pass the 8000km mark. I was on MH123 a few months ago, an 7 hour flight, and we took off close to MTOW.

I’ve done NY to Hong Kong in IF (which is about 3-4 hours longer) with the B777-300ER easily so either you aren’t packing enough fuel - especially given its a westbound flight - or you are climbing too high too early and burning too much fuel.

I would suggest using a flight planning tool like SimBrief.com - that way you can have an accurate amount of fuel to have and also correct cruise altitudes based on your weight and winds.

The range of 77W is way longer than you think! I had 4 hours of fuel left after a 17 hours flight from New York to Taipei. Remember it’s important to adjust your climb rate after takeoff, ~ 85% N1 is the most efficency way to climb. Also different aircraft had their most suitable cruise mach.

I suggest you to check out these topics.

That’s what it’s looking like for me, flying Newark-Singapore headed East. ~13 hours in and 41% fuel left.

You’re flying it wrong then, 77W should be able to go 20-21 hours even with a full load.

@Richard330

A330-300 can easily fly from New York city to Hong Kong, the distance is about 13000km

I wouldn’t say easily. I planned a JFK-TPE flight with a regular load (~15 hours) and it said I needed completely full tanks. JFK-HKG is even longer so you’d have to carry less non-fuel components.

But yes, you’re right that a lot of IF aircraft can fly longer than they can in real life (for example, I have a hard time believing a 77L could stay airborne for 32 hours in real life) but I think part of that is some built in redundancy so people who put their exact flight time in the game’s fuel estimator don’t crash so often.
