Hi Bob tait
Can you clarify what in the main indication when entering a microburst in cpl meteorology. There were several answers stating it was SEVERE TURBULENCE, and other of REDUCTION IN IAS and INCREASE IN ROD.

from IREX check this question and see if anything lines up

Select a hazard associated with microburst activity which would be most significant for aircraft in the vicinity of
an aerodrome-
[a] Severe wind shear causing drastic loss of IAS during approach.
Severe icing causing a loss of performance.
[c] Severe turbulence causing control difficulties during approach.
[d] Lighting strikes disabling navigation instruments,
