It's a PARTENAVIA P-68 Observer registered to Ravenair out of JLA.
Why is doing multiple loops at around 2500ft?
Observing?
Had maintenence and going for a test flight?
I like that stabiliser. I like it.
It's Ernie, repeated bombing runs over Greggs waiting for Binners to turn up.
In all seriousness might be doing air quality monitoring?
Lidar survey?
Trying to do a penis shape
@thestabiliser nails it
As did Kimbers to be fair. looks like they do whatever sensors they can hang of the wing
Maybe they accidentally dropped something important and aren’t allowed home until they find it!

That is more likeley the LiDAR shape, they have been doine different patches each day.
Looking for Premiership footballers' wives in swimming pools?
It might be LIDAR, but with extra loops to time their crossing of the flight path of Manchester airport.
Hopefully LiDAR. We need more LiDAR coverage.
Assuming it is air quality is anyone else struck by the irony of flying a plane round in loops to do this or is it just me?
is anyone else struck by the irony...
That was exactly my first thought, too
