(Digging up some info regarding REACTIVE windshear detection within the EGPWC.. Mode 7.. We obviously are looking for a sudden increase in IAS without a corresponding increase in Longditudinal Acceleration at trigger altitude etc conditions, but there is more to Mode 7 than just this; Watch this space). Although by definition Reactive Windshear detection means that you are already 'in it' (the microburst downdraft spread) it is the very early stages of the windshear, and hopefully applying the correct 'escape procedure' gives the pilot a fighting chance to get out of it.
