Christmas-Tree

There is an A 380 on a test flight over Germany painting a christmas tree with its flight track.

The sky markers dropped by Bomber Command on Germany in WW2 were known as "Christmas Trees", I guess this is not a repeat?

Looks like they didn’t allow for drift, it doesn’t look symmetrical. Not as impressive as Boeing’s Dreamliner?

There's an A380 in the hangar at CDG that's probably a Christmas tree by now ...

Interesting that today's aircraft, MSN 232, first flew more than a year ago, but has yet to be delivered to Emirates.

Somebody leaked the Emirates 2018 sim profile for the Canarsie approach.

Superb!

More seriously : That is amazing what one can do when programming an FMS . This one is a bit complex , with the 360s to simulates the balls, so I guess this has taken a little while to program . For those in the know. : is that just done on a PC in an office and a then sticking a USB flashdrive to plug in somewhere, , or 1/2 hour of typing coordinates on a FMS keyboard ?

Nail the corners in the FMS, pull HDG, do 360....

Airbubba :
most flight plans these days are uplinked over the radio using data protocols that are claimed to be notoriously insecure
Thanks for the reply . But AFAIK a Flight plan is strictly coded: waypoints , 5 letters codes. DCT, etc... Outside of these I believe it is only Lat/long and Distance in between. Tedious work to make a Xmas tree no? . Plus I would not know how to enter a perfect 360 on a flight plan

I wonder if there is a Boeing article somewhere on their recent effort that might explain the process. The Gulfstream test pilots out of SAV also seem to do a little drawing at times but I don't know if it's generated in advance.

It's been a long time since I've done a maintenance test flight but the actual filed flight plan was simple and we requested altitudes and headings once airborne.

Here is a piece on the recent 787 track during an ETOPS test flight:

Due to the very shallow turns, I would suspect they flew using airspace fixes only as a reference and much of the nav planning was done manually prior to the flight, using the FMC data for drift correction and not primary navigation control, although I suppose one could limit the bank angle using MCP or FMC. Of course, this would be a cinch to accomplish via coordinated ATC vectors.

Tannenbaum shape and the country of origin and flyover is quite fitting.

I have never seen a completely symmetrical Christmas tree (at least not a real one).

Enter a hold where you want the circle, once you turn hit immediate exit.

The baubles are approximately 21 nm in diameter, flown in 6 minutes, so about a Rate One-Third turn.
