That's really interesting about the extra weight of the antenna unit and the increase in TO figures. I was only thinking the other day (and was going to put this in the Ask the Pilot thread) what impacts the antenna units had so thanks for sharing!Not at all Boof! I don’t know everything and also rely on other people’s knowledge to get the right answer. So thank you for that. Unfortunately there’s no company document that tells me which one has the Wifi’s or not so when I first get into the flight deck I’ll check the overhead panel for the system controls. It’ll add 300kg to our take off performance figures if installed.
What I'm more interested in is what is the impact in drag between the VA unit which is quite streamlined, and the QF unit that is quite the bubble? I would imagine the VA unit is much better (of course I don't expect you to be able to compare them). I recall reading years ago that the old Live to Air antenna back in the DJ days had a real impact on fuel burn due to it's size and was one of the reasons that DJ charged for using it and hence also one of the reasons it was canned.
From memory the article mentioned that when DJ approached Live-To-Air they expected to be able to use the same antenna as Jetblue was using in the USA but the Foxtel satellite was different and hence needed a bigger antenna on board. I wish I could find the article I read it in online but I think it was actually a print article in Friday's Australian in the Aviation section about 10 or so years ago when the canned it.
Thanks,
Boof
