How to define holding pattern using command in bluesky.how to designate fix apart from waypoint using bluesky inside airspace ?

Dear Amitoj, There is not yet a validated HOLD command. It is being worked on, We have two candidate plug-ins which will add this feature, which are being tested. For now, you’ll have to do it manually with ADDWPT and check out some AT…. Commands. By setting commands ready when reaching a waypoint (<acid> AT <wpinroute> DO) should allow you to manually constructs a holding pattern.

Hi,
My hold works. I will paste the code I used. UTREV is the holding fix, I paused BS at the 1min after the outbound turn (to get the coordinates) and created a wpt In called UTRHD, this is the end of the outbound leg for a 210kts restriction. The rest is self explanatory. I did not do the sector join, but started at the holding fix. Turns are standard rate 1.

UTREV hold is outbound 280 and 1min legs@ 6100alt

set trail to dt=2 for smooth displayed pattern.

Based on 210kts 1min approx 3.5nm, 160kts approx 2.7nm, 100kts approx 1.7nm

While somewhere in the Hold :

HOLD1 direct UTREV

HOLD1 AT UTREV STACK HOLD1 DIRECT CT2T1; HOLD1 VNAV on

Not sure you can add a second scenario while the first is running, that's the manual part. Tried to make it work with ATDIST etc. but it became a bit "messy" :-)
