National Research Council of Canada Convair CV-440 (CVLP) departing Ottawa (YOW/CYOW)

Really cool catch of this classic, nice smoking departure. The aircraft really does look interesting with the modifications.

Fantastic catch! Huge like

[@AviationNZ]

Woah!! Very nice catch! These are so rare! Loved it!

[@michaellehman1549]

Catching RESEARCH 9 over east central Illinois right now with ATC (121.35) requesting block for operations. I suppose something interesting about the ice/freezing rain/snow event going on today. IIRC the level requested for the block were between 4,000 and 9,000 feet with cloud tops at about 7,000. Pilot sounds like it may be the same fellow on the radio in your video. Enjoyed it greatly. Moderate icing in PIREP just now. Sounds like they are operating around CMI within 5 mile radius.

She was doing an Icing Research study with NCAR and FAA from Jan 27 to Mar 8 based out of Rockford. We definitely had some great icing events

That's a cool looking prop! Nice catch :)

[@allenlutins]

This exact same aircraft just landed at Binghamton (NY) Airport and immediately took off again. We are having a wintry mix of rain, sleet and ice, with significant ice accumulation - apparently this aircraft is sent for research purposes to areas in the region that are experiencing weather like this.

Nice catch! This one's been around somewhat often lately.

[@JayaviationLV]

AWESOME

[@DullesPlaneSpotter]

This is a nice catch! I thought the CV-440 with the turboprop conversion was the CV-640.

[@andersonnettleship845]

Actually the CV-580 name is not official but was from the marketing department at the Original Frontier Airlines which was the first airline to operate this conversion. Officially those aircraft are CV-340A or CV-440A. with the A standing for Allison (the manufacturer of the turboprop engine used in the conversion, and it demanded on which airframe was converted since both the CV-340 or the CV-440 could be converted by replacing the P&W R2800s with Allison 501 D13 or 501 D13H Powerplants, 13’6” 4 bladed Aeroproducts Propellers, a 10% enlargement to the surface area of the tail along with numerous other modifications that didn’t change the appearance of the aircraft. This themed a good airliner into a GREAT Airliner that was considered a “Hot Rod” of the sky thanks to the huge increase in available power!

@@andersonnettleship845 Good info Anderson, and to add a bit more, this particular Convair CF-NRC was the first Convair 440/580 to receive the Hamilton Standard 54H60-77 prop conversion. a huge step up in operational performance and maintenance from the old Aeroproducts.

[@Russell1971]

I thought this was a Convair 580, not a 440, even if it is a research aircraft. Nice colors, though. Kinda makes me think of and reminisce about those American Eagle CV-580's that once served at my birthplace or hometown airport in Tyler, Texas, during the mid/late 1980's. They came over from Dallas, and were gigantic (almost 737-size) when compared to the Twin Otters they took the place of - until the SAAB 340Bs arrived in 1989.

Great video of an oldy but with 21st Century technological advances In my neck of the woods, (Fort Wayne, Indiana USA) CONVAIR 440's were the mainstay serviceable aircraft for Delta Airlines in the late 1950's. and early 1960's Link: www.wings900.com/cms/images/stories/jreviews/32186_IMG0884_1225174969.jpg
