Don't do this!
A lot of PPruners who operate in the states will be familiar with Land and Hold Short (LAHSO) clearances, where a modified LDA is used to allow an intersecting runway to be used at the same time you are on yours. (This was the subject of a recent PPrune thread). The procedure is not without some risk, and US ALPA had recommended their members reject LAHSO clearances. BA and the RAF have prohibited the use of LAHSO when offered, and put RMK/UNABLE LAHSO in section 18 of the flight plan.
Now the Canadians have their version - called Simultaneous Intersecting Runway Operations (SIRO). It is essentially the same.
I noticed it on the taxi chart for Goose Bay earlier in the week, it was also referred to in the ATIS.
Like LAHSO, I would advise pilots to reject SIRO clearances.
