It would really depend whereabouts you are on the ILS!!!
Most ILS's start at 10 DME, ATC will usually bring you to the start point of the ILS and then clear you from there.If by 8DME you are full scale deflection on either LLZ or CDI, then I would suggest that you start climbing away and trying again!!!
If you are at 2 DME, you will find that the needles go too fast to try to re-intercept.At this point you will be very close to the ground, and probably very close to the Mapt anyway!!!
Bottom line????if you let the needles go to full scale deflection during an ILS....you shouldn't be flying the bloody thing to start with !!!!
