BAE 146 or Avro over Rickmansworth

[Foz2]

Hi,

Noticed the above twice this week at relatively low level (1500 feet ish ) routing east ( skirting the north side of Heathrow zone). Havent seen it before on this routing. Just wondering what it might be?

I'm guessing part of the Royal flight out of Northolt?

Thanks

Or even inbound to Northolt from the northwest corridor....
