Below are some V1 speeds for some aircraft in Infinite Flight, please note that these calculations where made in ISA conditions at 0ft, and and it is an estimate.

Before you look at the table, this is what the abbreviations mean:

-RWY=Runway length, -10.000ft means less than 10.000ft of runway length, and +10.000ft means longer than 10.000ft.

-LOAD=Airplane load in %, -50 means load less than 50%, and +50 means load above 50%.

-***KTS=The V1 speed in knots [IAS].
