Hi,

here is a VTOL tilt-rotor concept from 1925,designed by Mr. Conard Kleinschmidt.

Any idea what the difference between visual and blind modes are? Perhaps just the scanning angle or range gates?

Avionics / IFF Mark I
« Last post by Maury Markowitz on September 15, 2017, 11:43:22 am »
There's a fair amount of information available on IFF Mark III, and a little bit on Mark II, but practically nothing on Mark I that I can find. There's a number of vague descriptions and some comparisons between the Mk I and Mk II, but they tend to be contradictory, some saying you had to manually tune Mk I while others say it swept the CH bands. Even AP1093 only mentions the Mark I in passing, stating that 50 were made - while others sources seem to say 1000 but I think they mean the Mark II.

Anyone know of a GOOD source on this topic, one that's more than a few pages long? I'd love to see something that has the actual circuits in it.

35 GHz in 1948?

That sounds highly suspicious.

Where is the background to call the Harrier a "Flying death trap"?

While the Harrier is a flying death trap, it really couldn't have been worse than F-104G.

Depends if the same lack of training issues were there - the real underlying issue with the so-called F-104 issue.
