[Flightgear-devel] YASim bug: airspeed

2003-02-19 Thread David Megginson
I've found a serious, and surprisingly not-previously-detected YASim bug. The calibrated airspeed does not allow for wind. Here's an easy way to test it: 1. Take a YASim plane (such as the J3 Cub), fly to altitude, then level out. Note exactly where the horizon is on the screen, and recor
