Photos of new Airlift Northwest helicopter EC135 N139AM

Over the last week, I have seen a new emergency airlift helicopter landing at the hospital.

Airlift Northwest - EuroCopter EC135 tail N139AM

I’ve seen this airframe type in use before, but the livery is different from anything I’ve seen to date.

One of the nicer aspects of this type of aircraft is the ducted tail rotor. This abates most of the rotor noise. Although calling it quiet would be a lie, it’s a lot quieter than the Agusta A109 un-ducted tail aircraft most commonly used in this area.

It also appears to provide more room for equipment within the fuselage. I can’t guarantee that I’ve properly identified the airframe, but it appears to be a Eurocopter EC135.

Unfortunately the photos are not sharp at all! I’m not at all sure why. Using the new camera (which I know works) and my trusy 100-400 ISL Canon lens (which I also know works). Must have been the very slow (100/th sec) shutter speed I was trying to use to capture blade movement. Oh well.

AirLift Northwest photos – Canon 20D + 400mmL IS lens

The last couple of days have been pretty nice. I had my older 20D camera body loaded with the 100-400L Zoom and next to my desk. More than a few times a week, the AirLift Northwest helicopters bring people into the trauma center at Harrisons. So, I decided to snap a few pics.

They have a number of helicopters, and at least two different models currently in use. This one, photographed on two separate days. I believe this to be an Agusta a109.

Note about these photos. These are re-sized by the blog software, and they loose a little bit of their quality. The originals are tack-sharp. I’ll have to look into adjusting the blog software to not mangle my photos. Not sure if it’s possible but worth a try.

I have to build one of these!

21cCKCy8p-L._SL500_AA280_The Estes Big Bertha is one of the old-school rockets from my youth. Never built one, but I’m thinking more and more about it with the boy getting into this, and wanting to put large payloads up in the air.

While looking or a decent photo of the thing, I ran across this video of a Big Bertha rocket with video payload. Now.. this is pretty neat. Looking at the lauch areas these people are using, there is no reason we should not be able to pull this off at our ‘secret launch site’.

There is a shorter version of the same rocket, that I’m considering building and painting up like an old WWII V2.

Something to do while it rains.

That gives me 9 months to finish it.

St. Maarten aircaft landing videos

While talking about cool places to go, I was looking up links to St. Maarten (visited there in 2001).   Which, inevitably brings me to look up YouTube videos of landings there.    Here are a few that I really liked.. the last one gives you a REAL feel for how hairball that approach is!

Airbus A340 landing. Keep our head down:

No, really, you want to keep your head down! (KLM 747)

First of the takeoff videos. Does not show the human windsocks but.. you sort of get the idea:

What it looks like inside the jet. Yeah, that mountain really is pretty damn close!

This is the longest of them all, at more than 7 minutes, but there are some great shots of the takeoff there too (check time mark 2:00).

Shortly but goody. It looks like the jet is just at the fence while you are standing them having sand hit you at near super-sonic speeds. Good times!

Here is a short one shot from the Sunset Beach Bar.

Now.. this is the most hairball of the bunch. That fence on the end of the runway is only 5′ tall for a reason!

And, finish it all off with a pilot’s view of SXM

I’ve pirated the pilot’s comments from his video post since, you might never see them viewing the video in my page:

Landing St.Maarten from cockpit 747. After nosewheel landing camera touched windshield causing crackling noise.

For those viewers who made comments (or new viewers who are thinking about making the comment) that this approach is too high and/or too fast or whatever else you might think, here some free 😉 flying lessons from someone who’s flying B747’s for 20 years:

On an approach on instruments a B747 should cross the runway threshold (= the piano keys) with the main wheels at ± 35 ft above threshold. The 747 is so big that at that point the altitude of the cockpit is 35 ft higher, so the cockpit is at ± 70 ft when main wheels cross the threshold.
On a visual approach, as is the case here at St.Maarten, we have to have some more margin. Normally the pilot aims to see the runway threshold disappear under the nose at 80 ft (mind you, the main wheels are at that moment still NOT above the threshold) to have sufficient main wheel clearance.
If you look at the video and notice the altitude callouts, you’ll see the threshold disappear under the nose at the call 50, so actually I am a bit too low in stead of too high. (In fact I am only too low for a visual approach. If you look at my landing at JFK http://www.youtube.com/watch?v=q4YoXy… you will see that I cross the threshold also at 50 ft, which is normal on an instrument approach. Note: the automatic altitude callouts you hear on this video are Radio Altimeter altitudes. The Radio Alt is zero when the main gear is on the ground with struts extended.)

Now, there are quite some viewers who think we landed too far on the runway. What follows from earlier explanation is this:
We approach a runway at a three degrees approach angle. If main wheels cross the threshold at the correct altitude, the main wheels will hit the runway at approx 900ft (300m) behind the threshold, that is, if you don’t flare the airplane. If you look again at the video and wait till you hear 50,40,30,20,10 and see the solid white markers, they are at 900ft behind the threshold and the plane touches down right behind them, because I did flare the airplane. (Passengers seem to hate hard landings!!)
THIS IS THE NORMAL TOUCHDOWN POINT FOR A B747.
The FCTM(=Flight Crew Training Manual) from Boeing says: flare distance is approx 300 to 600mtr (=900 to 1800ft) beyond the threshold.

So, please, stop nagging about this landing being too far on the runway.

And then something about too fast: On this approach the 747 weighs about 260.000 kgs. The required approach speed is then 150 kts which is about 175 mph or 280 km/hr. So what about TOO FAST? If we fly slower, we will fall out of the air!!

Airbus ‘Fail by Wire’ flight systems, under review

Airbus fly-by-wire systems have been under scrutiny since their 1988 ‘debut’ in the A320. A less than stellar demonstration this technology:

Now, the http://www.timesonline.co.uk/tol/news/world/europe/article6612165.ece are reporting that these same systems, combined with potentially defective pitot tubes, are being blamed for a pair of crashed, and have reported in many non-fatal events where failed speed sensors made the aircraft very difficult to control.

The first US incident occurred on May 21 when a TAM Airlines flight from Miami to Sao Paulo, Brazil, lost primary speed and altitude information while in cruise flight. The other was on a Northwest Airlines flight, on June 23, from Hong Kong to Tokyo.

Accounts on the internet from the pilots report a desperate struggle to keep the jet in the air.

Article: Airbus could be asked to ground all long-range airliners

There have been two storm related Airbus incidents in the last month. I’m sure many are looking into the possible connections.

As one of my favorite bumper stickers says:

If it ain’t Boeing, I’m not going!

The tragedy of Air France 447

Since the disappearance of Air France 447, an Airbus A330-200, (the exact same model of aircraft flown by Northwest Airlines, that I took to Amsterdam last month), 800px-nwa_a330-300_n805nw_arpI have been following the news reports pretty closely.  A lot of speculation surrounds, what the call the doomed flight, but until they get the ‘black boxes’ this is mostly speculation.   However there are some unique bits of data that the aircraft’s monitoring systems sent to AirBus (or maybe Air France, it’s not clear to me where the messages were sent) that the events leading up to the crash occurred over a 10-15 minute time period.  Plenty of time for pilots to issue a ‘Mayday’ message if they’d had any indication of an impending problem.

From the various reports I’ve read, I’m going to start to assemble some timelines, and references to the article sources as possible.   It will likely take me a day or so to get this collected.  Once I have managed to do so, a follow-up message will be posted.

My prayers go out to the families affected, and especially the passengers on the fated flight.  From what I have read so far, it would appear the aircraft broke up at altitude.  I can’t image what that might have been like.

747 flying off-course in NYC caused building evac

What the FAA indicates was a photo-op fly-by, coordinated with state and federal authorities, a Boeing 747 escorted by two F-16 interceptors, was flown down over the Hudson river (same approach pattern used by the killers on 9/11).  The sight caused a couple of buildings near the World Trade Center crater, to be evacuated.

Since it was coordinated, it seems it would have been nice of them to tell the people in the buildings not to panic!   Geez.  Nothing like needlessly scaring the crap out of people.

Some photos have been taken of this event by paniced citizens, I’ll post links as soon as I can find them (they are doing multiple passes of the jets so I’m sure plenty of photos will be posted soon).
