I'm not aware of any dispensations being granted, so technically it would be classed as off-track. That said, before it turned it was already at 6,000' so it must have been pretty light.

What is the point of sticking to SIDS - structured to apply appropriate separation on departure - when there is little traffic (in comparison to normal) to separate from ? In these circumstances, I would have abandoned SIDS in periods of continuing low levels of traffic. But, I didn’t work at EGLL !

That Finnair was indeed recognised as being "off-track", as can be seen from the highlight on the WebTrak plot:
I don't see what lack of traffic has got to do with not following the NPR.

A Dublin flight did the same thing shortly afterwards. I just wondered how it works, do they acknowledge a BPK clearance for instance but just amend it before take off on the basis that there’s no other traffic and they can comply with noise restrictions.

The SIDS where I did work, EGJJ, were not , as far as I can remember, mandatory as a required route if there was no traffic to separate from. As I remember it, we were at liberty not to use the SIDS should we require it (although, it was probably less hassle to stick with the SIDS - even if they were not strictly necessary). Anyway, thanks for setting me straight. I guess that once the a/c concerned in these instances had gained sufficient altitude so as not to exceed noise requirements, they were able to take a more expeditious route.

I haven't seen any announcement of an exemption from the requirement to follow the NPRs. On the contrary, Heathrow's coronavirus website, in introducing single-runway operations, gave the following undertaking:
"Q: Will there be new flight paths as a result of this change? A: Our flight paths will be unaffected by this change to our runway operation."
That said, more than a third of departures yesterday were "off-track" (i.e. radar tracking revealed that they were not following the NPRs).

Thanks Dave. It's interesting that some northbound 09L departures are off the NPR track. ATC are permitted to deviate from the NPR above 4000ft but webtrack indicates they are below this altitude when continuing beyond the point where they should have made a left turn. .

Polish AF C-295s have been regulars several times a week at Biggin for several years. I assumed it was the Embassy run but I have been led to believe they are often returning Polish ne'er-do-wells and fugitives... allegedly!

All of the NPRs only apply below 4000'.
