Vickers Viscount C-FTID-X

Pratt & Whitney Canada's PT6 test bed with a PW100 mounted on the nose.

01/22/2007. Remarks by Jack McKillop:

"This aircraft made its first flight on February 25, 1959 and was delivered to Trans Canada Air Lines (TCA) on March 8, 1959 registered CF-TID with fleet number '648'. TCA was renamed Air Canada on June 1, 1964. It was leased to The Sarcee Club between October 1971 and June 1972

It was sold to United Aircraft of Canada on November 27, 1972, and reregistered C-FTID-X, it was used by Pratt & Whitney of Canada for flight-testing the PW124 turbo engine with six-bladed Hamilton Standard advanced propeller to power the British Aerospace ATP. In October 1989 it was withdrawn from service and stored at St. Hubert, Quebec. As of this date, the aircraft is no longer registered in Canada."

    $\begingroup$ Well, that configuration does put the test engine and prop out in clean clear airflow, and.....and... erm... Ok that's it, that's the only redeeming feature I can think of. That thing must be a total pain on takeoff and landing, it would induce the most interesting vibration modes in the airframe, and limits pilots to people with strong stomachs, prone to neither vomiting in disgust not falling down laughing at the sight of their vehicle. Deaf would help too, with a rather strong engine mounted directly in front of their cockpit and very little to dampen the noise. $\endgroup$

    $\begingroup$ Not the prettiest bird ever. And 5 engine (not 3 as supposed by the OP) to boot! It's a test bed, though, and isn't designed to win beauty contests. Poor thing... I'll bet she's got a great personality! $\endgroup$

    $\begingroup$ I bet she's got the visibility of a Concode on landing. $\endgroup$
