Wastegate and PCV check?
In section 3.5 (Engine run-up) the Rotax 915 iS Operator's Manualsays, in addition to the Lane and Ignition check, a Wastegate and PCV check should be accomplished. It says this should be done at full WOT and over 4700 RPM! Does anyone actually do this as part of a routine pre-flight run-up?
It also says, "If possible the PCV Check and the Lane and Ignition Check might be combined in one check." However, I note that it says to do the Lane & Ignition check at 2500 RPM.
Maybe this is why the Sling TSi manual says to do the run-up at 4000 rpm, perhaps a happy medium to accomplish both checks simultaneously? Seems like in both checks you're just turning off lanes and checking indications remain within parameters.
Does anyone have more guidance or info on this check?
Thanks!
