The silly part of the O2 rule is one, crew masks are not designed for continued use, it’s emergency equipment; two, breathing even supplemental oxygen for long periods isn’t good for the user—it’s very dry; finally, the instances of loss of pressurization above F350 is easily meets the one on a bil...

Jump to postRyanair have FOs with 185h total time and have a perfect safety record.

Jump to postOut of curiosity, how much does the proximity of the two propellers in the coaxial configuration affect performance? I imagine there would be a fair amount of turbulent air around both props. Or maybe just the aft prop. Or maybe not? There is of course an effect on the rear prop. But net-net perfor...

Jump to postIf airports are closed in emergency, pilots are supposed to find a desolete area and crash the plane while saluting.

Jump to postsafe safer I have to say this is one of my biggest pet peeves with discussions about safety. I feel like there are way too many questions of the form “Is XYZ safe” - as if there is a “Safe-o-meter” that can give any sort of sensible answer to that question. Safety is a culture that needs to permeat...
Jump to postThe statistical analysis would be frames lost per 100,000 departures. The MD-11 simply had more crashes per departure. Over time, there was enough data to establish this as a fact that future MD-11 flights have a greater probability of loss of control crash than a 777 or A330. Around ten times more...

Jump to postI think, to put it simply, even if there is a revolution in efficiency and fuel prices and alternative fuels, etc, running more than two engines is less efficient. So say, for the sake of argument, that they figure out how to power an intercontinental jet airliner with hydrogen in a reasonable fashi...

Not an engineer, but I’m pretty sure that the 380 wasn’t able to have the wingspan that it should have because it had to fit into existing gates at airports. Therefore it was kind of doomed from the start, which is why they don’t make ‘em anymore.

Jump to postSomething I think people who are not pilots may not think about is that other than 1st generation regional aircraft like the DC-9'S and 737's, pretty much all commercial jets from the 727 on up had at least 3 in the flight deck and sometimes a navigator making it 4. So the pilots who back then stil...
Jump to postSully’s landing on a nice smooth river aside, those life jackets are really just there to make you feel better. Whether the engines are under the wing, over the wing, or on the tail, if the airliner you’re riding in goes down in open water you’re going to die.
Have a nice day?
Because there has been a long-serving, more robust version of MCAS on military craft for over a decade. In other words, it's a fixable issue within engineering constraints to simply use the more robust version (which Boeing should have done from the start). No The KCs are basically already kinda fl...

I’ve always wondered, if DLC engaged automatically and caused the yoke to move the spoilers while the plane maintains a fixed pitch, how did the aircraft know what pitch to maintain?

Jump to postYes, we do have full authority and, yes, get good at using the brakes symmetrically. GF I fully respect that point of view and your training. But my question is, What if...?

Jump to postThat raises an interesting (at least to me) question: When you touch down at, say, 140 knots, assuming you’re not using autobrake for some reason, does the pilot have full differential braking authority in both pedals?

Jump to postI don’t think that a prolonged or permanent grounding is that far out of the realm of possibility.
