I was looking over the wiki article on the Gimli Glider and noticed updates exchanged the term "floatstick" where "dripstick" was previously used. I had not heard this term but a little googling about indicates the former is a newer version of the latter, with the advantage being that it doesn't pour fuel out of the tank.
Looking on the web I found a number of references to fueling the 767, and this one is about the 767-200ER (which I believe is the same/super-similar as the -233?). It talks about the "magnetic type dripless fuel measuring sticks" which seems like it is a floatstick. But this is a very recent publication, 2019, so perhaps this refers only to in-service aircraft after modification?
I also found any number of pages and/or reports that referred to it being a dripstick. This included the final accident investigation report. I also found a diagram showing the 767 did use dripsticks, at least at some point, but it is also possible they simply called them that in spite of it being magnetic. Earlier references seem to use "magnetic dripstick" so it might just be confused terminology.
- When did floatsticks (magnetic dripsticks) become common in general, not 767 specifically?
- Did production 767's ever come with floatsticks from the factory? Always?
- If !2, were in-service aircraft updated to use a floatstick?
