Fault injection system allowing to trigger over 140 system faults either at a specific point in flight or randomly during a flight phase.Detailled model of each ADIRU including alignment, small pressure sensor differences between the units, switching of sources for PFDs.High fidelity fuel system including inflight CG control by pumping fuel to and from the tail tank, fuel jettison, manual and automatic transfers between the different tanks.Quantitative bleed model considering the bleed mass flow for engine start, wing anti-ice air conditioning packs etc.This is most noticeable when flying on RAT or with wind milling engines Quantitative hydraulic model considering the maximum hydraulic flows of the different pumps as a function of engine speed.This gives realistic surface floating angles if a control surface is lost due to combinations of hydraulic and computer faults. Hydraulic model for flight control actuators computing hydraulic flow through the actuators, the control surface hinge moment, maximum feasible deflection etc.Fly-by-wire system with reversion between normal law and alternate law 1, alternate law 2 and direct law as per real life logics.
