If what you claim (simulators do not have the required fidelity for crosswind landings) then this suggests the zero-zero flight time claimed by the manufacturers is bunkum and that regulators and airlines have been conned.
FFS manufacturers do not claim that their devices are “zero-zero flight time” only that they are capable of meeting the level D requirements of JAA –FSTD-A or FAA equivalent.
It is the operators responsibility to certify the device and the operators responsibility to certify his training programmes that collectively results in “zero-zero flight time” accreditation.
As I’ve stated previously, these current Level D requirements are archaic. ICAO 9625 Edition 3 was an attempt to more the industry into the 21st century but the regulatory authorities are
all dragging their heels with the implementation and whilst the FFS manufacturers have adopted most of the recommendations and todays Level D sims are being built to Type VII standards, the testing and checking is still being performed against the old regs.
