The STAR (or SID, or IAP) will say what kind of navigation performance capability is required to fly it. If your avionics can't tell you where you are with the precision necessary to fly the procedure, you can't fly that procedure. Pick another way to get yourself where you want to go.

My guess? They are panels that can be removed to get into the leading edge of the wing, and with age and repeated removal, the seams / gap filler material loses its paint. 5694401,2106321 http://www.lufthansa-technik.com/documents/5875801/6291465/171123_SOFIA_039_2x1/637ed5e5-e2e9-48c4-9f78-ae7e1623...Jump to post
Echoing others, the black stripe on all stretch 777's is over the main gear for the tail camera. 6147645,6597809,6350005 Although JAL's airplanes have the black stripe on all of their wings.

Yeah, but how much is each carrying how far? Maybe the 757 is below it's max payload but is it still carrying more farther than the maxed-out MD-90?Jump to post
@convair880mfan Swept back wings enter the gust (a "w" gust, i.e., a vertical gust) more progressively, so the load factor builds up more slowly. The sharper the gust front, the more obvious the effect. For a bit more technical details, see https://apps.dtic.mil/sti/citations/ADA381486 (o...Jump to post
Florianopolis, in general, on the Airbus A320 series, we normally don't intentionally allow the airspeed to increase to the point where the auto-retract system kicks in, but sometimes, particularly on the A321 since it is a heavier aircraft, it does. During climb out, we are more focused on the var...Jump to post
Sorta. It depends on whether you are above or below auto-retract speed. The flap movement speeds on takeoff and approach are normally a bit different, so in effect it makes a difference whether you are approaching or departing. For example, you might not retract to clean until 230 knots when depart...Jump to post

On landing it's a unique combination of flaps, landing gear, speedbrakes, fuel vents . . . every airplane is a choir for us to enjoy. On takeoff they say it's a combination of jet core noise blasting out behind the engine, and the sweet bird song of supersonic fan blade tips. Not as subtle as the ap...Jump to post
The motoring sequence can be as long as 2 or 3 minutes. So in LAX when you get pushed in to the alley, ramp is chomping at the bit to get you moving.

I mean it makes sense the air is thinner so the APU has to spin faster, but doesn't that also mean that there's less air to squeeze to the same pressures? The same power going in results in a higher rotation speed because the air is thinner for the same compression, in other words? Could it be becau...Jump to post

I echo what the others have stated. A couple speeding tickets will not foreclose a career (at the majors, at least), but that doesn't mean they're meaningless.

Save the DC-8 iirc, various regional jets, some Russian stuff, most aircraft have a positive nose angle to horizon when on a normal descent. I don't want to go too off-topic, but the big difference is the leading edge devices. As you extend and lower the trailing-edge flaps, the wing camber and cho...Jump to post
How does it manage to keep descending at such a pitch up attitude? 8 degrees of angle of attack and still descending. How does that happen? This is a subtle point, but I'm not sure you're getting it: Angle of attack is only part of whether you are climbing or descending, along with airspeed and thr...Jump to post
Let's go back to the basics. Imagine you're a student pilot sitting your Cessna 172. Your instructor points to the control yoke in front of you, and says, "You push and pull on this, and what are you controlling?" You say, "I pull back and I climb, I push forward and we descend."...Jump to post

Read up on Part 121.565 (b) says for engine failure enroute for three and four engine planes. You’re not a test pilot in this case, assuming simple engine failure, it’s authorized to continue.

You're gonna have to see what the checklist says to do with the engine failure.

I think behind the wing is preferred for CG concerns, but you have to have enough fuselage behind the wing for the deck loader and tugs and other equipment to have room to maneuver without banging into things like flap track fairings.

There are a lot of accidents that would have been prevented if flight crews kept their hands on things to make sure the airplane wasn't trying to kill them.

Is this of the largest 10 airlines at the time of the data?
In other words, if Delta and Northwest merged, that's the same number of flights (ish), and then the next month it's all their flights PLUS another new tenth airline?
