DU Aviation Experts: I have a couple of questions. [View all] gateley Jul 2013 OP

I feel it's to early to make any assumptions. Agschmid Jul 2013 #1

Hard to say. Arctic Dave Jul 2013 #5

Damn birds/FOD. Agschmid Jul 2013 #8

I understand that GPS altitude data has a margin of error... krispos42 Jul 2013 #49

One reason some instruments should have burrowowl Jul 2013 #66

What about air traffic control? gateley Jul 2013 #7

Yes quite a difference! Agschmid Jul 2013 #9

I'm not sure they land visually anymore. Arctic Dave Jul 2013 #16

It is by no means all automated HERVEPA Jul 2013 #30

They're asking that question on MSNBC right now. gateley Jul 2013 #34

askthepilot.com talks a lot about this issue and the misconceptions HERVEPA Jul 2013 #72

Sounds interesting. I'll check it out -- thanks! gateley Jul 2013 #75

Ground proximity would have been turned off because they were landing. napi21 Jul 2013 #76

The planes instruments and GPS tracking would give the pilot all the information. Arctic Dave Jul 2013 #2

Stuff does happen... Agschmid Jul 2013 #6

Not necessarily; Yes; Depends on the circumstances. NYC_SKP Jul 2013 #3

I know we'll learn more as the investigation continues, gateley Jul 2013 #20

Strange indeed. To make it so far and come so close to an uneventful landing... NYC_SKP Jul 2013 #24

1) yes; 2) yes; 3) yes - initial report was another aircraft on the runway. Pilot may have tried to leveymg Jul 2013 #4

Do you have a link for this? Agschmid Jul 2013 #11

MSNBC live interview with a female witness, about 2 hrs ago. No link. leveymg Jul 2013 #43

First I heard of that. Arctic Dave Jul 2013 #12

Thanks -- I remember stalling when I was flying years ago. gateley Jul 2013 #15

We're you watching the interview at the hospital? Agschmid Jul 2013 #21

No -- didn't see that (I was working today so missed all but surreptitious streaming snippets) gateley Jul 2013 #23

Now that is a valid question! n/t Agschmid Jul 2013 #26

Video here malaise Jul 2013 #62

Yes, you can see the other plane, but it may be on the runway closer to the camera. leveymg Jul 2013 #64

It was not on the same runway malaise Jul 2013 #67

That would have placed it between the witness and the runway where the crash occurred. leveymg Jul 2013 #68

Depending on the location of the witness malaise Jul 2013 #69

There are two possibilities. Savannahmann Jul 2013 #10

Do microbursts only happen with storms? Agschmid Jul 2013 #14

The article says there are two kinds. Savannahmann Jul 2013 #18

It's true! Agschmid Jul 2013 #19

How interesting -- didn't even think of that. gateley Jul 2013 #25

It's called Occam's Razor... Callmecrazy Jul 2013 #36

Oh THAT'S Occam's Razor!!! gateley Jul 2013 #42

The simplest explanation with available information is better, that's not the same as correct HereSince1628 Jul 2013 #52

The black box will tell all. Warpy Jul 2013 #13

Yes -- and somebody else mentioned a microburst. gateley Jul 2013 #27

Some thoughts from a total non-expert. Stinky The Clown Jul 2013 #17

Someone knowledgeable agreed that it is much different visually (water vs land) -- gateley Jul 2013 #31

This one? Agschmid Jul 2013 #35

That case produced the "Asoh defense" jmowreader Jul 2013 #44

That's hysterical! Thank God nobody was seriously hurt! gateley Jul 2013 #46

Jerry Harvey talked about this in his tape "The Abilene Paradox" jmowreader Jul 2013 #63

Yes! It must be -- that's right around the time. Ha! Haven't heard of a DC-8 in years!! Good job! gateley Jul 2013 #45

Extensive article (with pictures) on the incident... PoliticAverse Jul 2013 #56

A lot of speculation right now. The Velveteen Ocelot Jul 2013 #22

Is the flightaware tracking information correct? Agschmid Jul 2013 #29

Don't know how accurate their info is. The Velveteen Ocelot Jul 2013 #32

One of the experts on MSNBC mentioned how close the SFO runways are -- gateley Jul 2013 #38

SFO uses PRM (precision runway monitoring) approaches The Velveteen Ocelot Jul 2013 #39

Glide-slope indicator... Mojo Electro Jul 2013 #28

I think SF still uses the ILS. Savannahmann Jul 2013 #33

SFO runway 28L has a 4-light PAPI (Precision Approach Path Indicator). The Velveteen Ocelot Jul 2013 #37

Somebody has posted s/he heard it wasn't working -- gateley Jul 2013 #40

I'm thinking many of us will be learning a lot about the factors in the days to come. gateley Jul 2013 #41

Some thoughts on the crash today... Pilotguy Jul 2013 #47

Saw this tweet. Is it true? dkf Jul 2013 #50

Yes... Pilotguy Jul 2013 #53

Thanks. dkf Jul 2013 #54

Two questions related to this malaise Jul 2013 #74

Maybe yes yes canonfodder Jul 2013 #48

Yeah, I have no choice but to wait -- gateley Jul 2013 #59

landed too soon RILib Jul 2013 #51

I've always had a suspicion that the pilots were sometimes blamed to save someone else's butt -- gateley Jul 2013 #61

It has already been reported on UK tv news dipsydoodle Jul 2013 #55

Oh -- that IS interesting. Hadn't heard that on American news, of course. gateley Jul 2013 #60

FAA must have known about it Mr. David Jul 2013 #73

I am not a Pilot, nor an expert. But I have some experience in the field. Savannahmann Jul 2013 #65

Latest I heard about this accident is that the pilot flying was inexperienced in this type. Mr. David Jul 2013 #70
