Emergency landing Flybe Bombardier Q400 in BOH

[stothem1234]

What Airline was the 737 that this was filmed in?

[stothem1234]

Who filmed this? I'm assuming it's the FO of that aircraft but what aircraft is it and what airline?

[KairalaFC]

They are undoubtely on a B737, and most likely the EFIS series

[SenorSpode]

@KairalaFC Indeed. At the very least a -400, more likely a -500 or -600.

[ThomsonAirwaysFs]

LOL what aicraft was you in! The captain at the end LOL!

[chanrobi]

What does that mean high AoA on landing? Descends faster?

[hogey74]

It refers to the angle of attack - the angle at which the wings chop at the air. Optimum during cruise is around 4 degrees. The amount of lift increases with higher AoA until the wing loses lift suddenly at about 16 degrees and "stalls". The flaps increase lift and change the angle of attack so that the aircraft can land with the nose (generally) just slightly raised. Without flaps the nose must be raised higher, increasing the AoA so that the same amount of lift is created. Does that help?

[chanrobi]

Mmm. Sort of I was more referring to the video information that said that the high AOA was noteworthy. Wondered what makes this a useful technique when doing an emergency landing..

[hogey74]

Oh sure. The high AoA is only noteworthy here because it indicates that the flaps are not in use. Sometimes you use less flaps or no flaps on landing as a routine thing if the cross wind is really strong or gusty because flaps make the aircraft a little less stable. If you were landing in a field or with a busted wheel or something you would generally use full flaps because they allow the lowest possible landing speed. You would use a high AoA then too as that helps minimise landing speed.

[SenorSpode]

The flaps were inoperable. Your comments are excellent ones in explaining the correlation between airspeed, angle of attack and flaps. Obviously, when flaps are out of the equation, it's then a matter of setting up angle of attack and airspeed to regulate adequate descent rate for approach and landing. It's good--and rare--to see educated comments like yours here.

[hogey74]

Hey thanks and thanks again for the vid :-) If I am explaining it properly I must be understanding it ok... I hope my examiner sees things the way you do!

[hogey74]

Nice vid thanks! Love to see more. Not good if a system failure but the design would be certified to only tail strike beyond clean config stall speed AoA I imagine. That's what my flaps up 172 landings must look like I guess. Cool seeing it from inside a jet holding short - hope to be in the right seat one day soon myself. Thanks again.

[valicourt]

Thanx! W.

[SenorSpode]

I could see they were coming in real hot and nose-high, but that was a great approach. The very next day after that, I flew a Q400 from Seattle to Edmonton, Canada...it was uneventful. The plane made a definite believer out of me. I love the Q!

[hogey74]

Yeah they got some bad press with a few landing gear failures but I hear they are apparently pretty good. Qantas here has heaps and recently bought more. Bombardier makes some nice aircraft. As I was telling someone recently they were going to stop making them in 2001 but with 911 and fuel prices they are now more popular than ever. Almost as quick on short sectors as a 737 or embraer.

[SenorSpode]

The Q400 uses 30-35% less fuel than a regional jet of the same seating, their engines are cheaper to maintain, and not only is the speed comparable, but the Q400 requires less turnaround time between flights, which means it can maintain a schedule intended for jets. This is why Seattle/Portland-based Horizon Air--another major Q400 operator--is ditching their CRJs and going all-Q400. The plane is a moneymaker for them.

[devon2576]

ouch, one of those crashed in Buffalo newyork, last night at 10:20PM, and 40 passenegers, and 4 crew member. it was continental flight...flight number 3407.

[mayorofthenonsense]

what was the actual emergency there that meant that had to come in with that angle of attack with the flaps up? i went on a Flybe Dash-400 recently - quite impressed with the speed and acceleration. reasonably comfortable too..

[SenorSpode]

When you come in with no flaps, you need to maintain a certain sink rate. The only two ways you can cope are: Nose up (To a point, to prevent tailstrike) so the wing preserves a low sink rate and more forward speed to help the wing. It's elementary ground school stuff. If he had flaps, he wouldn't need to keep the nose so high up, nor would he need so much forward speed. Before landing they set the autobrake for MAX as well as used full reverse on touchdown. Hope that helps.

[Sinbad633]

Q400 doesn't have auto brakes, at least not Flybe ones.

[SenorSpode]

I bet Ryanair has no brakes at all...they probably charge their stand-up passengers for it! LOL

[Flyingspud247]

looking to be rated in private any takers?

[PlaneAU]

how do u know a pilot filmed it !!

[bmused55]

Um

They're sitting in a 737 cockpit. Thats a two man Cockpit. The angle the video is at is too far forward for a Jumpseat passenger to be recording it. The systems are operational and the plane is on a Taxiway... the evidence is overwhelmingly for the argument that this video was indeed shot by a pilot

[karldoyle2]

@bmused55 and at the end you can see an empty jumpseat ino tha comments old but how and ever jus thought i'd get tha out oh and the pilot recording this is parallel to his partner too

[PlaneAU]

HEY theres no proof that its an emergency you stupid people

[Phasy]

It's filmed by a pilot so they obviously could have heard it over the radio.

[emosandknives]

isnt that a dash 8 not Q400? (im not that familiar with Fly-be's fleet i've only seen their dash 8's and Embraer 190's (exeter) but yeah it was a weird landing can you explain it in more detail?

[ryanwarwick]

It is a Dash 8, but it's the Q400 variant of the Dash 8.

[MingGuoLi]

Those planes have a gear problem? Found 3 videos in 1 minute and all mentioned bad gears..... What angle of approach does a jet have usually?

[billythomas18]

y did the flybe dash need to make a emergency landing?

[kinsley2108]

looks like the flaps did not go down, so the plane had to come in fast with a high angle of attack. The left main gear also looks weird.

[jsmallwood2007]

I cant see flaps either should be noticable they stick down far

[halofreak200715645]

i can tell just by my FLIGHT SIMULATOR X that these guy swho made the video were in some sort of boeing, weren't they?

[13YearOldSteward]

Thats a Boeing 737 cockpit.

[halofreak200715645]

yeah, the skylights kinda give it away

lol

[halofreak200715645]

at the first few seconds, on the right, there are 2 small flashing red lights. what do they do?

[bmstyle]

those just warn you that this is a hold short point because at night its hard to see the line on the taxiway :)

[halofreak200715645]

so thats why those lines are there, i thought they were to keep planes a safe distance from the runway, to stop the wings hitting the other planes.

[OriginalAtomicSheep]

thats exactly why they are there and those lights are there as the other guy said so that at night u can see where that line is

[bmstyle]

ye those lines are there because you have to stop there other wise you'll cause a runway incursion. At night time they are especially difficult to see so those flashing light leave no doubt in your head that this is a hold short line. Also, the runway sign (the red one on the grass that says 18-36 for example) is always placed at the same level as the hold short like too so you know where it is exactly :) take care

[lemonfacesmells]

I saw this aircraft at BOH twice, and i thought it was a very weird coincidence, i thought it must have been a emergency or something, and on one of those times, i also saw a Flybe van drive past, any idea what was the emergency?

[valicourt]

All flaps up landing.

[justcallmemike]

flaps up landings arent terribly difficult, but they are a challenge with that added speed. normally i thought that since it was a Q-400 it would have the common problem of the nose gear not working.

[minimartinb]

what was whronge with it
