Convair 990 Coronado
Announced on 30 July 1958, the 990 (formerly known as the Convair 600) was developed from the Model 880 to meet the specific requirements of American Airlines and was given a longer fuselage and turbofan engines. The first Coronado flew on 24 January 1961. As a result of early testing, Krueger leading-edge flaps were added between the fuselage and the inner engines to increase elevator effectiveness and the outer engine pods were moved rearward to ensure speedier subsidence of vibration induced during test flying. The first 990 delivery was made to American Airlines on 8 January 1962, passenger services beginning on 18 March.
In February 1962 the company completed a speed and range/payload improvement programme for the 990 which led to the redesignation 990A. All aircraft in service were modified to 990A standard, with engine pods extended rearwards to reduce external drag; reduced droop on the wing leading-edge; full-span Krueger flaps in place of the former combination of flaps and slats; and a new fairing at the wing-fuselage juncture. By 1977 the last of the original operators had withdrawn their airliners from service.

I had many trips from San Francisco to Detroit with a stop over at O'Hare. This was in the mid 60's. On one trip with a tail wind we came within 30 seconds of setting a comercial speed record to O'Hare. The captain commented that if he had known that he would have pushed it a little bit. Five abreast seating was great if you took the left side where it was two seats. Unfortunaetly a high maintenance airplane wiith dirty engines.

990s were more roomy than 707s: 5-abreast seating gave more room per passenger than the Boeing. They seldom flew over .82-.85 because of range considerations. They held 15,000 gallons/fuel. 707s & DC-8s held more. So range was limited. Convair needed to offer other engine manufact-urers too. But they were precise flying machines with a limited market. And they were strong!

Used to see Spantax Coronados at Birmingham ( uk ) Elmdon airport. Totaly took them for granted along with the Boeing 720 ( Monarch ) Comet 4 ( Dan Air ) Caravelle
( Sterling ) and God knows what else wonderfull stuff . " Don't it always seem to go that you don't know what you got till it's gone..."

I flew the CV 880 880M 990. All great planes. Also flew CV88o The Lisa Maria for Elvis 1975 77.

You don't mention that the 990 was powered by AFT FAN GE engines - unlike the Pratt & Whitney front fan engines of the day that powered the 707 and the DC-8. The aft fan of the engine was less then a desirable location and it's (the engines) performance was less then desirable - hence the poor sales and demand for the aircraft.

CV880 and 990 fuselage widths were less than 707 or DC-8, but not a seat width's less, so the seats were actually a little wider than the others. Less passenger capacity hurt, though. Fuselage skins were thicker than Boeing or Douglas, although exact dimensions uncertain. On a 990 test flight after overhaul at HAECO in HKG, M.91 warning bell rang freqently. Truly, a pilot's airplane.

The 3-view is a 990, not a DC-8 as someone else says. It's a poor-man's drawing, so don't use it for any model building. The San Diego Air Museum has tons of photos on line if you want more specifics.

3 view is not a cv990.
The egine pods were moved back for flutter problems.
Vortex generators were used to reduce drag.
Later deliveries, high fuel cosumpyion, and the 5 seats across were the down fall.

I only once flew on a Coronado, a Swissair flight from London Heathrow to Geneva, and found it a comfortable, if somewhat cramped aircraft because of its five abreast configuration which put it at a disadvantage compared to the contemporary Boeing 707 and Douglas DC8, with 6-abrest seating. (I believe this was one of the main reasons for the commercial failure of the Convair four jet airliners).

WHERE ARE THE ASB'S??
Do you have any comments about this aircraft ?
