I don’t know how to take a video on iOS, so I’m going to use a combination of words and pictures. Ps do this in solo.
Mission: to land a 737-700 slower than a Cessna 172s landing speed.
First you need to pick the 737-700 and an approach for an airport. Make sure your landing not taking off. Next you need to go to weather and make it like the picture below:
Now hit fly. As soon as you start go to weight and balance. Make everything empty:
Now resume. The plane will really want to pitch up so bring up the flaps for the whole approach. When you hit 500 feet or about the place in the approach in the picture below bring down the flaps to full.
Okay, now the tricky part. Trim as high as you dare and perform a 20 Knt GS landing. Comment below how this worked for you. Also try a take off and see how fast you can climb😉.
