A few more observations; Not until post #67 does anyone talk any sense at all, then to post #97 and 98 for a bit more sense.
If the RJ was stationary, as in parked, then the speed of AF is totally irrelevant. Speed would only be relevant if AF had been cleared to taxi subject to the RJ being clear.
AF and the RJ would have been on different frequencies, AF on ground and the RJ on the frequency of the company controlling that part of that terminal area, that is the American way. The controller talking to AF would not have known the actual position of the RJ, as far as he was concerned it was on stand.
It is common practice to park two aircraft on one stand, side by side, if they are small enough, which may be why the RJ shows to be to one side of the centre line for the stand. If the RJ had stopped short of the stand stop point it is his duty to advise this to GMC as he may be an obstruction to taxing traffic.
If the AF has been cleared to taxi along taxi way A then it is not an unreasonable assumption that the taxiway is clear of parked aircraft.
Posters such as Sevenstrokeroll and Nitpicker330 may not get the blood they are baying for.
