| Landing St. Maarten from Cockpit 747 |
 |
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. (Actually I am only
too low for a visual approach. If you look at my
landing at JFK
http://www.youtube.com/watch?v=q4YoXyYBbYA&feature
=user 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 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!!

| Cockpit Video of Blue Angels Flight. Beautiful Footage |

Blue Angels footage mixed with some classical
Americana music, perfect for the Annapolis
setting. If you complain, you are a fool, and
will be blocked.

Ride of a lifetime over the USNA on 22 May 07.
One of the most fun things I have ever done.
Unbelievable experience.

| Friendly Fire Cockpit Video Iraq 2003. Matty Hull Killed |

Friendly Fire Cockpit Video Iraq 2003
Lance Corporal Matty Hull, 25, from Berkshire,
England was killed in Iraq in 2003 by (un)friendly
fire from U.S fighter jets.
For years UK/US security denied the existance of
this cockpit video but here it is, finally
revealed.
IMHO. It's all too easy to blame the clear
incompetence of the U.S pilots. YET AGAIN this
shabby, amateur Labour government must be held
accountable for failing YET AGAIN to equip our
troops with up to date equipment. It seems rather
than investing in advanced 21st century
communications equipment that would have prevented
this, they relied on the cheaper alternative of
using the colour orange. Pathetic! I hope the
facts of this aspect don't get buried in the
typical knee-jerk anti-American jingoism that is
so trendy in Britain these days.
PS - Please don't vote Labour again, it's
embarrassing. The P.G Tips monkeys could do a
better job (and are far more aesthetically
pleasing than Prescott)
