Re: Why no second commercial airport for Atlanta?

Given that there isn't a suitable airport already built (unless the C-130 line is closed), hundreds of millions would have to be spent and need to be paid back, just to cut down on drive time for people on the North Side of Atlanta. Consequently, any flights from a second airport would start at a co...

Re: Development paths for new scope compliant aircraft.

.... If I understand the current situation in the US correctly, there is a (co-)pilot shortage because the FAA requires 1500 flight hours for an ATP license. Would it be a good idea to introduce a new scope level where first officers and pilots can book their flight hours. This would require new re...

Re: Development paths for new scope compliant aircraft.

I wonder what optimizations could have been made in the CRJ-900 as hypothetical update. The -1000 changed enough that it merited a new type rating from the FAA, but gained things such as a fly by wire rudder. I believe RTM flaps on the -1000 allowed some weight savings that weren’t able to be reali...

Re: Development paths for new scope compliant aircraft.

The benefit of the legacy carriers is the number of options. If mid size cities lose flights to connecting hubd because there isn't an aircraft in scope, there will be knock-on effects as fewer planess fly trunk routes. A city that goes from 10 flights a day on one airline to many fewer is in a down...

Trends in Fleet and Hub Structure

The recent discussions about Airbus and Boeing's strategy and problems with aircraft production if we could be in for a shake-up of the overall aviation industry over the next decade or so. Production rates of the A350 and 787 are approaching one every two or three working days. These high rates see...

Re: Are Shared Ownership Private Jets Hurting 1st Class Airline Sales?

GalaxyFlyer has it right. A key use case for private jets is the difference they make for industrial-class corporations. Think of someone like GE, automotive manufacturers, paper mills, and developers. These companies have dispersed operations, and even if they are headquartered in a major city may ...

Re: Delta not a fan of second airport in Atlanta

Delta has reason to be scared. Much of Atlanta's wealth is concentrated to the north of the city. Coincidentally, everyone talks about building a new airport there. A new airport that gives just a few gates to American, United ad Southwest might sway big spenders who would have non-stop flights on a...

High Wing Civil Aircraft

Reading through these forums, it seems that a number of aircraft face limits on engine size due to low ground clearance. This is not a problem faced by large military aircraft such as the B-52, C-17, and AN-124. It seems that a future aircraft design might be able to use a larger turbofan if the win...

Re: Airbus Working With Emirates on New Order for Flagship A380

It's easy to underestimate the human side of things when looking at financial issues like an aircraft program. Leahy was the ultimate author of the market forecasts that made the A380 "business case" and his attachment to the big bird must have some sway in the organization. His retiremen...

Re: Seat size regulations in the US

These tests are usually conducted by fit college students. Not an accurate cross section of passengers. No they are not. Search for evac test videos to see for yourself. But to everyone who argues that a tight seating configuration is a safety issue I will counter argue that some recent crashes sho...

Re: Does 1 airplane on the ground at an airport roughly equate 1 million passengers per year?

Depending on how you count, this might be possible. If we take your number of 1,000,000 passengers per year and divide it evenly by 365 days per year, there are 2,739 passengers per parked plane. If an arriving and departing passenger counts separately and we generously assume 10 "turns" p...

Re: Airbus is examining 'A380-Plus'

how does a stretched narower frame become more efficient than a shorter wider frame? You have to look at wetted area per passenger - first and foremost - for fuselage efficiency. Narrower vs. shorter widebodies don't show dramatic differences on this metric. A narrowbody will save you wetted area a...
