 * '''-g:''' Instructs YASim to generate space-separated tabular data instead of the usual solver output. This can be redirected to a file and used in various plotting programs to visualize the actual lift, drag, L/D curves. The columns of the output from left to right are: AoA, Lift, Drag, L/D. (aoa in degrees, lift and drag in G's).
-* '''-a <altitude in feet:>''' Run the solver at the given altitude in feet.
+* '''-a <altitude in meter:>''' Run the solver at the given altitude in meter.
 * '''-s <speed in knots>:''' Also run at the given airspeed in knots.
 {{Note|The values generated by this method are for the aircraft taken as a whole, as solved by YASim, so they differ from the values of the wing airfoil.}}
