I did this, using Fortran 90 for the math and Tcl/Tk for the plotting. There is no single equation; instead there are several cycles of calculation nested inside each other like a Russian matryoshka. The innermost loop calculates all forces and moments at the point in time at which the calculation stands. The next layer iteratively trims the airplane so ...

A "good" landing with a 737NG as described in the Flight Crew Training Manual (FCTM) is flown with a pitch that has increased by 2 to 3 degrees during the flare. The resulting vertical speed is not specified, but will only depend on the airspeed at a given pitch increase. Remember, that a good landing requires a stabilized approach first, so you ...

Spoiler deployment on a routine landing using published technique does not cause pitch up on a typical big jet. The moments and forces at play do not cause any alarming nose up tendency. Generally the published technique recommends that (jet) thrust be brought to idle to coincide with touchdown which means Thrust Levers/throttles be at the idle position a ...
