This was a press release, so I can post it in its entirety:

Record Number of Planes Grounded Brings Percentage of Global Fleet in
Storage Close to 9/11 Peak, Says Ascend
Tuesday February 24, 9:50 am ET

Almost 1200 Aircraft Taken out of Service in 2008; Boneyards Benefit

LONDON--(BUSINESS WIRE)--The impact of the global economic downturn
continues to be felt by the aviation industry, as new figures reveal
that a record total of almost 2,300 jet airliners are now parked. 1,167
aircraft were grounded last year, making 2008 the worst year for
cutbacks since 2001.

According to data from Ascend, the world’s leading provider of
information and consultancy to the global aerospace industry, more than
11 percent of the global aircraft fleet of 20,293 is now in storage.
Taking into account future decommissioning, that figure may even rise to
match the 13% reached at the end of 2001, following the 9/11 terrorist
attacks on the US Then, the global fleet comprised only 15,950 planes,
so a similar share in 2009 could mean a total of some 3,000 idle airliners.

Chris Seymour, Head of Market Analysis at Ascend, says, “The aviation
fleet data shows that at least 400 more aircraft are scheduled to be cut
during 2009, with groundings being announced almost daily. This is
having a negative effect on aircraft values and lease rates, and
creating real challenges for the aircraft financing community.”

Regional breakdowns also suggest that most regions have felt the impact
of a weakening global economy. North American carriers have announced
fleet reductions totaling almost 800 aircraft since mid-2008, while
European carriers have parked over 450 aircraft and Asia/Pacific
airlines at least 230. The Middle East region has not been affected to
the same degree however, with Emirates airline announcing a planned 14
percent increase in capacity in 2009.

According to Seymour, the severe increase in aircraft groundings is a
clear indication of drastic cost-cutting measures by airlines as they
adjust to the challenging global economic climate, consumer
belt-tightening and reduction in cargo traffic.

“Some reduction in capacity is typical over winter months as passenger
traffic decreases. But this season’s fleet cuts were far more severe
than those of the recent past.”

Planes on ice in desert sand

One benefactor of increased plane groundings is set to be the aviation
storage business, based primarily in the Arizona and Californian deserts
of America.

Aircraft boneyards are a good barometer of the state of the arirline
industry, Seymour says. “Generally speaking, the fuller the aircraft
boneyards, the tougher the market conditions. Storage facilities are
already filled with a surplus of older technology 727s, 737s and MD-80s,
many of which will never fly again. However some younger aircraft and
many of the 250 current generation aircraft will eventually be returned
to service once the industry recovers.”

Ascend’s fleet data gives insight into today’s volatile aviation market.
“The increase in groundings shows the extent to which consumer demand
has lessened, and is necessary if airlines are to adjust to the more
challenging operating environment,” says Seymour. “With new deliveries
still likely to be around 1,000 this year, subject to financing,
airlines also have to park older aircraft to avoid even more surplus
capacity.”

Note, the ascend web site doesn't seem to work well, you may need to
save the files before yu can view them. The second chart is interesting.

1292 aircraft parked in the last 12 months.
287 parked 12-24 months
474 parke 2-5 years
231 parked for over 5 years


I think age of aircraft might be more interesting. Having a charter
showing percentage for each age class (1-5 years, 5-10 years, 10-15,
15-20, more than 20) would give better idea of wheter aircarft are being
retired, or really just being parked temporarily.

737-200, DC-9s, DC10s, L1011 etc that are parked are really just
awaiting transformation into beer cans. But a 737-NG, 320 or other
recent aircraft are really being parked due to fleet rationalisation (as
opposed to fleet rejuvenation).

According to data from Ascend, the world¹s leading provider of
information and consultancy to the global aerospace industry, more than
11 percent of the global aircraft fleet of 20,293 is now in storage.
Does the following rough calculation make any sense?

Roughly 20,000 active aircraft

with each spending 12 hours/day in the air on average
(think I read that somewhere long ago)

=> 10,000 aircraft in the air at any given instant

with at least 100 people per aircraft on average
(probably more like 150 or even 200?)

=> 1,000,000+ people in the air somewhere, every
instant of every day (on average)?

If you believe that Atlanta has a typical mix of aircraft, then the
average is 82737/994 or approx 83 pax per aircraft movement. [2007
figures in thousands]

OK, thanks -- that's a sensible piece of data.

What I recall reading some years ago and being surprised at at the time
was a flat assertion (from some technical and presumably believable, but
now forgotten, source) that larger commercial airliners are in the air
on average of 12+ hours/day, averaged over years on end, **even counting
periods when they're totally out of service for scheduled maintenance**.

The implied reliability impressed me; the schedule planning that must be
involved impressed me -- if this is in fact a "true fact".

The figure doesn't surprise me.

If you head on over to airliners.net you can find people who put
together detailed papers on fleet utilization for companies such as
KLM and AirFrance, etc.

It's a bit geeky, but, interesting none the less.

The Brave New World of privatized digitally rights managed data sounds
good, but when you combine complex business strategies with today's
incompetent programmers, the result is that customers probably won?t
get what they paid for. In an airplane, in the clouds, this is not
comforting. - Phil Greenspun

Gotta love those 744s that come steaming out of Lambourne hold too
fast and have everything hanging out with gear down before it crosses
London Bridge. Spoilers up, flaps full, engines screaming etc. Noisy
as hell. I should know - it is my morning wake up chorus.
