Cruising speeds

1

(Use a320 for example at 20000ft)

Whenever I cruise over speed, I get a violation. (350kts) Yet, I have seen people cruise over 400kts in same aircraft at same FL and not get a violation. What is happening?

The speed that’s shown with other people is the ground speed (airspeed +or minus wind speeds.)
That’s why often you see them flying 400+knts.

If you fly at M0.78 with the A320 (which is by default the Max cruising speed) you can still reach a ground speed of 400knts or higher, while the airspeed might just be 250knts at 35000 ft for example. It depends on the tailwind you’re having.

This is a quick explanation, please correct me where I could be wrong.

Sounds right to me :)

Thanks!

I’m definitely wrong in the explanation. But you will be fine with this advice.

The speed shown for others refere to groundspeed, if you want to know their airspeed you should tap on the plane, then on the black bar and all the info about that player should appear: altitude, airspeed (kias or mach), groundspeed, apart from personal info like grade, xp, violation count etc

Sounds about right, I will do this :)

If you have discord and are on the IF server, you can use bot commandes /Aircraft [choose whatever plane you wanna fly in IF]
And it will give you info about the Max allowed cruising speed. These are accurate and will NOT give you any overspeeding risks.

Keep your Cruising altitude in mind too and everything will be alright.
For now happy and safe flying in the IF skies.

I do have the discord, about to go do that.

Thanks!

There are two speeds in aviation, air speed and ground speed.
Airspeed is the speed in which you move through the airmass.
Ground speed is the speed in which you move over the ground.

In infinite flight violations for over speed are based on your airspeed.
If you go to hud, you should be able to see the maximum airspeed of your aircraft before you get a vio.
Here is a good read:

If you have any additional questions, feel free to reach out. :)

For what it’s worth, with no wind or a slight headwind you will still probably be over 400 at max IAS. This is because at altitude your TAS is going to be higher than your IAS. GS is then TAS plus or minus wind component. Sort of a pedantic detail, but just worth noting if we are comparing to other aircraft and trying to work out what our GS will be for a given IAS.

Thank you for the better explanation 😅
