Any idea on what the oldest aircraft is that still has engineers on staff at the original manufacturer to handle support issues?
Jump to postAny idea on what the largest historic aircraft without hydraulic flight controls is? I know that the 707 used aerodynamically controlled flight controls. Anything bigger/heavier?
Jump to postThis wasn't intended to be a FBW sidestick vs mechanical yoke discussion (which it has come down to), but rather a acknowledgement that a yoke is a horrible control interface considering that it blocks the instrument panel and hits your/the other pilot's knees.
Jump to postI do have a short torso and long legs so that might be some of the trouble. I have to put the seat all the way up which also leads to my shins touching the instrument panel when I'm on the brakes.
Jump to postWhy are modern aircraft designs still using floor mounted control columns? A column and yoke is about the worst ergonomic design that I can imagine especially with a fly by wire aircraft where a side-stick is feasible. You have to look and reach around the yoke to see and manipulate the instruments....
Jump to postDo aircraft that rely entirely on spoilers for roll control (no ailerons) still have roll authority when the wing is at a zero lift angle of attack? Spoilers roll the aircraft by decreasing lift on the down wing. If the wing is at a zero lift AOA there is no lift to kill. Am I wrong in my thought pr...
Jump to postAre there any aircraft currently in service with the US Air Force other than the T-38 that are powered by straight turbojet engines?
Jump to postI wonder if the current vertical tail/rudder has enough authority to handle an outboard engine failure? With the current 8 engines if one fails you don't have all that much differential thrust compared to losing a full 40,000lb thrust from an F117.

Many gasoline engines are getting in excess of 100hp/liter on 87 octane gasoline. Is it possible that new generation aero engines could ri...

Jump to postDoes anybody have a ballpark number for the fuel flow of a GE90-115B at TRT and sea level?
Based on what I know about the CFM56's fuel flow and multiplying to get equal thrust, I would guess that it is around 40,000-45,000 lb/hr. Does anyone have firsthand experience with this?
99% chance that he got outed by the company and was told to take it down.

Jump to postThis type of flying is why that C-17 crashed in Alaska.
Any idea who the guys flying this aircraft are? They don't appear to be USAF pilots.
I was just thinking about the ABL program when I realized that it seems like an awful lot of money to spend when the countermeasure is to simply strip the paint off missiles and polish the aluminum to a mirror finish. I'm sure that the engineers though of this.
Jump to postWhat I was getting at is how do the lights themselves work. Are they incandescent, fluorescent, LED? I suppose I should have specified that in the original question.
Jump to postBoth F-18s and C-17s have the same type of green light strips on their fuselage. How do these work?

Jump to postI don't see why not. Stationary turbines often run on gaseous fuels (mostly natural gas). Liquid fuel is nice because it can fit in irregular spaces without being under pressure.
Jump to postA B-1B bomber consumes about 250,000 pounds/hour at sea level full afterburner and roughly 20,000 pounds/hour at cruise. Like tom said, there are so many variables that this question is unanswerable without specifics.
A CFM56 will burn about 8-10,000lb/hr on takeoff and 2-3,000lb/hr at cruise.
