Estimate from the variant's published specs, 0-5; scores are only comparable within one criteria year. DC-9-10/-14 (JT8D-5/-9, MTOW 90,700 lb). Range 1,590 nmi (This Day in Aviation) vs 1,300 nmi for the -15 (Wikipedia table) = 0 at either. Capacity typical 90 single-class (72 in 12F+60Y mixed) = 1. Speed 490 kn at 25,000 ft (TDIA) = about Mach 0.81 by my arithmetic (speed of sound 602 kn at 25,000 ft ISA); MMo 0.84 = 3. Runway null: DC-9 airport-planning manual is a scanned image with no usable text. Comfort null: the two reviews are Delta -50 pilots. Efficiency null: no published fuel-burn figure for this variant was found (airport-planning manual has none; operator pages checked give only fleet-level savings). Only 2 reviews found.[1]
Today’s jets almost fly themselves, but the DC-9 definitely does not. Delta Captain Scott Woolfrey will fly the airline’s final DC-9 flight. He said because pilots have to always be “hands-on,” most enjoy the plane more than other commercial aircraft.
"The DC-9 is a workhorse," he said. Woolfrey knows how these planes perform. He's flown them since 1997
It took some time and a bunch of pencils, but by 1963 Douglas had a design in mind that resembled both the BAC 111 and the SE210, but ended up outperforming them both where it counted.
