Abstract: A gas turbine engine includes a bearing compartment that has an inlet. A supply line splits into a supply conduit and a reservoir conduit that are fluidly parallel to one another for a length. The reservoir conduit fluidly rejoins the supply conduit at a junction. The supply conduit is fluidly connected to the inlet, and the reservoir conduit includes a flow restrictor upstream from the junction. A main pump is fluidly connected to the supply line and is configured to supply a lubricant to the bearing compartment through the supply line and supply and reservoir conduits in an operating state. The main pump has a non-operating state in which the reservoir conduit is configured to slowly refill the supply conduit through the flow restrictor.

Abstract: The present invention combines the geographical coverage possible with fixed, pre-defined route segment costs (e.g. the legal speed limit) with, wherever possible, richer time dependent costs. A user of, for example, a portable navigation device, can therefore continue route planning as before to virtually any destination in a country covered by the stored map database, but wherever possible, can also use traffic data with time-dependent costs, so that the effect of congestion with any time predictability can be accurately taken into account as an automatic, background process. It leaves the user to simply carry on driving, following the guidance offered by the navigation device, without needing to be concerned about congestion that exists now, and whether it will impact his journey.
