if the air temperature is at ISA (standard temperature) for that altitude, then density altitude and actual altitude should be about the same. If temperature and pressure are standard, then density will be standard. If temperature is standard and pressure is 3% higher than standard, density will be...Jump to post

You're right-- I forgot that things changed after the Panagra merger.Jump to post
Could Braniff carry local passengers JFK-MIA in, say, 1970? No, because they didn't fly that route. A Braniff plane could fly the route, operated by Eastern, and it could carry local passengers. I'm guessing it always had been allowed to, since the interchange flight started in the 1950s. Probably t...Jump to post
Looks like when CO started JFK-HNL in 1986 it was their only flight out of JFK. Airport Activity Statistics shows it as a DC-10-- did CO have any 747 flights in 1986?Jump to post

rate of climb depends on lift and T/W. That's the problem-- none of us knows the aircraft's thrust in the climb. Based on static sea-level thrust, a 767-300 would climb just as well as a B-1. But the B-1 set a climb record at 150 metric tons: 3 min 50 sec I think it was, brake release to 9000 meter...Jump to post

Circa 1946 TWA transatlantic flights left from Hanscom rather than Logan-- maybe because Logan wasn't good enough?
CO started EWR-HNL around 1987-88. Don't think it ever did SFO-HNL.
You could see an eastward contrail over Oakland in the afternoon-- had to be CO's nonstop to EWR. All the others were overnight.

Runway thresholds need to be staggered with parallel runways less than 2500 ft apart to enable this. The rule states that the landing must happen on the closest threshold and the departure from the furthest one. For every 100ft below 2500 ft, runway thresholds need to be staggered by 500 ft. Guess ...Jump to post
Offhand guess: US airlines always wanted to fly over Cuba, and had more to gain from a reciprocal agreement with Cuba. Don't recall when Cuba started scheduling flights that wanted to fly over the US. In any case, they did fly over NY to Montreal in the 1990s.Jump to post

Scans of paper copies of many years of Airport Activity Statistics are at hathitrust.org. Easy to find as long as you click on "catalog" before you search. Table 7 is the one that shows how many departures of each type for each airline-- it's alphabetical by state.Jump to post
What's the maximum number of seats in an A380, if we avoid cruelty? Truth to tell, you're not going to get good answers here about CASM-- we're too ignorant. But if someone did know about costs, you'd have to spell out how many seats you're going to allow in each aircraft. That's the only thing that...Jump to post
I finally noticed your private message, and replied. Airport Activity Stats shows 40 CO 707/720B departures from ABQ during 1967, and 30 727s. Don't have a 12/67 QR OAG, which I guess is what you need, to see if the flight was then a 727 or 720B. Do have a 1/68, tho-- I'll check it eventually.Jump to post
Don't recall how long Fornebu's runway was-- 2100+ meters? Maybe this guy has a diagram
Yup-- says 2370 meters. No date on that one, tho.

Aircraft departing runways 1 (or OAK) and headed south or west sometimes request the Bay Tour: maintain 3000, remain over the water, depart the Golden Gate Bridge heading whatever, then climb and maintain whatever.
Didn't know they ever did that for runway 28 departures, but sounds a possibility.
