.....however the SAR grid you posted doesn't say much without a date and legenda.
Here is for instance a map with grid west-northwest of the last known poisition, flown by one of FABs C130 on 6 June, which does seem to cover the area you're pinpointing in your highly interesting earlier post on the possible crash site:

But perhaps that is the point you and others try to make: it was six days after.
Having said that, interestingly enough your presumed impact point
is within the northen part of the grid of 10000 sqkm of search area along the flight path on the same map, flown by FAB's EMB RJ 99's and fully completed by them on 2 June (re FAB note nr 6 of that date)
