you can also see those vortices when it's humid at F1 races as air is 
forced across the rear wings when the cars are on long straights or 
gentle curves.

We used to sail Albacores out of the marina at the south end of the runway
at National, and in the summer there is often no wind in the morning. So
the game was to catch the tip vortices from landing aircraft. They would
either knock a boat flat or send it planing across the water for a good
distance, depending upon how the vortex landed on it. They would also set
up little water spouts where they touched down on the surface. Lots of
energy, like there was any doubt!

Re: [MBZ] beware of A380s

2017-03-18 Thread Peter Frederick via Mercedes
There is a similar story about the DC-6.  Leaving the gust lock lever in the 
locked position duringwould lock the horizontal stabilizer in a slight "up" 
attitude, which could easily be compensated for by dialing in some trim.  At 
least once the lock was accidentally engaged in flight, and like all propellor 
driven airliners of the time, speed increased as fuel was burned off and as the 
speed went up, so did the tendency to climb.  With the initial design, it was 
possible to more the lever freely in flight.

When the co-pilot discovered the lock was engaged and pulled the lever to the 
unlocked position, the "down" trim shoved the nose down hard, causing an 
unexpected power on dive, from which the pilot managed to to recover by rolling 
out of a fully inverted attitude -- not something one would normally do with a 
plane load of passengers.

The gust lock was changed so that it could not be inadvertently activated and 
the problem never occurred again, except for the instance where a pilot 
"demonstrated" it in flight -- he resigned when he got to the ground before he 
got fired.

A DC-3 crashed here in Evansville in the 70's killing a local team, including a 
friend of mine for similar reasons -- on the DC-3 the gust lock is a wedge 
inserted by ground crew, not an internal mechanism, and the ground crew failed 
to notify the flight crew it had been inserted.  The air crew failed to do 
"range of motion" control testing before taking off.  The plane took off on 
ground effect, and promptly flew into the hill at the end of the runway because 
the elevator were locked.

Re: [MBZ] beware of A380s

2017-03-18 Thread Scott Ritchey via Mercedes
Back in the 80s, the USAF had a program for spouses to ride along on
designated "safe" training missions.  This program suddenly ended when one
such C135 crashed, killing all aboard.  The investigation concluded that a
spouse in the left seat had clicked in a bunch of nose-down trim (thinking
she was pressing "push to talk" which was a similar rocker switch on the
yoke for intercom and radio).  When the autopilot tripped off the sudden
dive pinned anyone not securely strapped in against the ceiling, which,
unfortunately, included the pilot and copilot.  By the time any of the real
crew could reach the controls, the aircraft was already in an unrecoverable
Mach-tuck dive.  Aviation and guns should never be taken lightly.

Re: [MBZ] beware of A380s

2017-03-18 Thread Larry Turner via Mercedes
Speaking of A380s, there was a show on Smithonian channel called "Air 
Disasters" which features various airliner/aircraft incidents. Yesterday 
they featured a A380 with a crew of 3 that was on auto pilot when the 
pilot brought his (9 ur old?) daughter and 15 yr old son into the 
cockpit and he first let the daughter sit in the pilots seat and she let 
her hands rest on the control yoke.  Then his 15 year old son had his 
turn.  He did the same with his hands, but being stronger, he was able 
to put more pressure on the yoke.  That's when disaster struck as a 
feature of the new A380 (and many other planes) kicked in -- when 
pressure is put on the yoke for approx 30 sec part of the Auto pilot 
becomes disabled.  At that point the 15 y.o. teen was controlling the 
rudder while the autopilot continued to (try to) control the rest.  
Evidently this is a feature some commercial pilots like.  At that point 
the auto pilot tried to keep the plane on course by adjusting the other 
controls.  It appears the crew was not trained in this feature.  
Eventually the plane began to roll while the son was still in the pilot 
seat.   But maybe forces kept him seated.  So the situation continued to 
deteriorate as the plane began to dive then roll and slow spin as the 
crew tried to regain control - the pilot was seated once again.  
Eventually they appeared to pull the nose up and stop the spinning, but 
as the plane climbed they over-corrected and it was almost vertical when 
it stalled.  It appeared the auto pilot was still in partial control 
during all of this which happened in approx 40 sec.  All these maneuvers 
used a lot of altitude and they ran into a mountain.  The airline was 
the Russian Aeroflot and they said that while what the pilot did was 
technically illegal many did it. Hmmm.  I pray American commercial 
planes have a little better cockpit security.


It's amazing to see the amount of info they get from the cockpit recorders.

Yes, but the smaller plane was no Piper Cub. It was a twin engine jet.
The air traffic controllers need to keep these things separated by more air.
There was only a thousand vertical  feet between them when the A380 passed 
overhead.

Nope, not thrust, but weight makes the wake turbulence. Any heavy aircraft,
even gliding with minimal thrust makes massive rolls of air. Always touch
down on landing beyond the touch down point of a "heavy", and always
lift-off before the point the "heavy" lift's off when following one on
take-off. Stay above the wake turbulence, not below it.

They probably should have been further apart even if it wasn't a 380
