Ifølge Simworks Studio:
The aircraft pulls to the left when trying to climb up a steep slope.
This is a limitation of the ground handling model in Microsoft Flight Simulator. Even if the nose wheel is turned, the sim does not consider static friction or its effectiveness correctly until a minimum forward speed has been reached. We considered reducing the P-Factor but, because the Kodiak has a strong pull, that would render the flight model unrealistic in 99% of the runways. Therefore, the only solution to taxi up a steep slope is to begin with a running start.
