ANC_747 Rwy6R approach and TCAS encountered Anchorage

[AirCanada04]

I bet the transponder was on from that airplane that landed previously because it is required to be on before crossing a runway. Nice vid of the majestic 747-200. I used to fly the Air Canada 200C (Combi) long ago.

[F1gm3ntsc4pe1]

too short rway for 747 i think

[teddy96]

nope. Its just nice as during the approach,the pilot lost most of the speed already. By the time the pilot is at 500ft, the Airspeed of the b747 would be approximately 130-140knots. So it would be possible

[sqy391]

@F1gm3ntsc4pe1 rwy length: 10897 ft

way enough

[Moumou727]

I think the TCAS alert was triggered because the previous aircraft was vacating the RWY and taxiing with transponder still in ON position, in order to cross the other RWY...

[ASUSfan08]

TCAS is triggered only when there is conflict in flight path. the traffic alert indicates the shut down of TCAS after capturing Glide Slope.

@Moumou727 Mode C yo.

[akushta]

A TA is generated with the other traffic id within 1200ft and 6NM of ur ac.

[maskedhedgehog]

incorrect ... e.g. at FL200 a TA is generated if the intruding aircraft is 40 seconds from an assumed collision ... an RA is issued when it's 25 seconds away

[FsxCaptain]

Great video. Which airport?

[akshona]

Anchorage, Alaska

[morrisonak]

Right on centerline.

[tombirkland]

Relatively smooth landing at ANC consider how rough it can be. How close or far away does traffic have to be to trigger TCAS? There's so much departing traffic at Lake Hood and the airstrip that, even everyone is seen and being seen, TCAS would be chirping more than typical for a lower 48 approach--maybe Boeing Field triggers TCAS as much?

[Kambanicity]

depends on the alltitude

[themightyjfox]

6 miles Horizontal and 600 vertical .

[Kambanicity]

600 feet u mean?

[themightyjfox]

600m or 1200ft

[omfgCantGetaUsername]

uhm... 600m is not 1200ft that's more like 360m or something around there.

[jakbowtell]

It becomes a traffic alert if the plane is within 6 miles of the aircraft.

[ichbinsdoch]

Cool! :-)...traffic traffic

[AuburnPilot]

Way to high on the approach, but a great touchdown!

[raythespy]

You think so? I can't quite make out the PAPI lights but I think they're showing that the plane is on the proper glide slope(you know 2 white lights 2 red lights).

[AuburnPilot]

Yes, for most of the approach the PAPI lights are 2 and 2 but, close to touchdown, it changes to 3 whites and 1 red. Just seemed like he touched down closer to the halfway point... not the standard 1/3.

[raythespy]

Yeah now that you mention it I see it. Sorry. You're right. And it was a nice landing

[w5cdt]

Not way too high. The PAPI showed two reds and two whites. I think the telephoto lens was giving a distorted view of the runway. If you touch down *at* the PAPI's they should stay 2 and 2 until the last few feet.

[AuburnPilot]

Maybe the lens did give a distorted view, but at 2:02 the PAPIs did change to 3 whites, 1 red. (High) Can't make out what they were when he crossed the threshold.

[canonboy123]

You have no clue about how the PAPI works. His approach was perfect.

It's normal that the number of the white lights raises after a specific altitude.

[John19182004]

Remember this is a 747 - the cockpit is more than 50' high when the maingear touchdown, so it appears higher than what would seem "normal"

[maplefreako2006]

o.o

[maplefreako2006]

Only 747 can land on anchorage?

[jdwu]

No,any kinds of aircraft can.

[maplefreako2006]

hahaz ok thank,because I saw another video of yours,after landing on snow runway,i see all 747 only.=P

[jdwu]

Yes!Because I have my duty on it.

[737NGFO]

What aircraft?

[jdwu]

Boeing 747-200.

[e53e54]

It is likely to overshoot the runway. :P

[jdwu]

It's OK,-Because we flight from Sea to Land with different groung effect.

[ghettomax]

sweeeet!

[jdwu]

Thanks!qhettomax

[badboyblue99]

747??

[jdwu]

affirmative!badboyblue99 and Thanks again!
