In the technical documentation I can't seem to find the mast length, that's why I'm asking. I am assuming "Tirant d'air" is the length from the water level to the top of the mast. I'm interested in the length of the mast itself.
Bonjour a tous.
Jean Paul, I am in the same situation as Lasse trying to find out the length of the mast), the only data I can find is the "tirant d'air".
Can you or anyone else give the data in meters ?
yes, you're right : "tirant d'air" is the heigh from water to head of the mast. I am not sure about the english translation (air draft, ... heigh, ... overhead, ... ??)
So here is what I have measured on my 1090. I assume all 1090 are masted the same way (whereas there are 2 mast lengths on the 1040) :
- Tirant d'air : 15,08m
- Tirant d'air with the VHF antena : 16m
- Length of mast : 13,68m
It’s in the technical documentation of the site (
1090 Manuel Prop.pdf), page 19/53 :
At the bottom of this page the length of mast for roof whistle version is 13,51 m and panoramic roof version 13,68 m.
