I apologise if you have already covered this in your previous extensive postings on this subject:
Please direct us to the source document from where you are able to substantiate your claim that;
"This HC2 was equipped to interrogate the (UHF) portable DME sets"
And expand on your implication that the transponder on this aircraft was capable of displaying a range from another transponder.
Specifically, which model of airborne transponder allows this, and where was the associated range readout displayed in the cockpit of ZD576?
If you must persist with this line let us at least drag the discussion out of fantasy, and back to reality!
I am very suspicious of your motives, so let's put this to bed once and for all!
Thank you.
