We present analytic results for one of two types of planar QED two-loop integrals for µe scattering including finite lepton masses. No approximations are made, such that the results are valid not only in the limit of a small electron mass. The results are expressed in terms of multiple polylogarithms with algebraic function arguments in a representation which allows for fast numerical evaluation in the physical phase-space.

This article presents the development of fly-by-wire control laws used for the highfidelity simulation of a new transport category aircraft. Beyond structural and gain design aspects for normal operations, envelope protections and limitations as well as mode transition issues are also addressed. As the control system is to be adjusted to changing aircraft datasets at different levels of fidelity, particular emphasis has been put on a high level of automation in gain design and system assessment routines. For lateral dynamics, eigenstructure assignment is used as the design methodology whereas pole placement is used for the pitch axis.
