During the EDA step, we discovered that Landing_Gear, Thrust_Rev, and Flaps can be removed from the dataset. This is because they only contribute during the landing of the airplane, which is out of our scope.
Normally, we wouldn't do this, because the relationship between the input and the output is quite complex, but for our simplified exercise, we have decided to use only the following variables—Time, Altitude, Param1_4, and Param3_1.
We could also use Principal Component Analysis (PCA) to reduce the number of variables to no more than five.
