Bevor die Differentialgleichungen aufgestellt werden, ist es in der Flugmechanik und Flugregelungstechnik üblich, gewisse Vereinfachungen vorauszusetzen. Die wichtigsten Vereinfachungen lauten
...........................................
Der Drall der rotierenden Triebwerke wird vernachlässigt. Bei kleinen schubstarken Flugzeugen, kann diese Vereinfachung zu ungenauen Ergebnissen führen *(Kreiselkopplungen*).

coupled gyroscopic forces / gyroscopic effects
Explanation:
The German construction is telegraphic, and it is quite common in documents of this sort. Unlike common English usage, the parentheses enclosing the term xxx are shorthand for 'in connection with xxx' or 'this is related to xxx'.

I'd be inclined to render this in English as '... can lead to inexact results (due to gyroscopic effects)'.

neutral  Kcda: Excellent! However there is probably a new issue. Is it really quite? The engines. I doubt it. The gyroscope & bearing idea is possibly an easy way out. :)
