Not sure whether to post here or in historic (given the age of the photo) but…
I was browsing airliners.net when I came across an image of LOT Yak 40
http://www.airliners.net/photo/LOT—Polish/Yakovlev-Yak-40/1403334/L/
My question is what are the three small aerials on the top of the nose? To my inexpert eyes they look like IFF aerials as fitted to Warsaw Pact fighters of the period.
If they are, was this so that the aircraft could be quickly requisitioned by the military if the need arose? Did all civil airliners behind the Iron Curtain carry such devices?
Thanks

Yes – they are the aerials for the SRO-2 IFF system – called ‘Odd Rods’ by NATO.

Thanks guys! ‘Odd Rods’ – there’s an expression I’d forgotten existed!

They are standard on the Yak-40 are they not? Cause during my Russia trip last september I saw several Yak-40s, and they all got the three aerials.

Yes they did….
