Keep encouraging the young
At the beginning of January a 15-year-old student pilot in Tampa, Florida deliberately
flew a Cessna 172 that was barely a year old into a bank building. The youth did not
survive his spectacular suicide attempt. A small amount of damage to property occurred,
but no one else was injured. In the light of the terrorist attacks of 11 September 2001,
his suicide has triggered a discussion as to how sensible it is to allow young people to
learn to fly.
My opinion on this point is crystal clear: one can never start young
enough. For a number of reasons I believe it is desirable to introduce young people to
aviation early on. It is not necessary that their sights should be set exclusively on a
career in the pilots seat of a Lufthansa plane. Flying teaches one values and skills
which are also in demand in other industries.

PILOT REPORT
EC130: impressively quiet
Extremely stable in flight and particularly quiet this is the impression one
gains of the EC130B4. Eduard Kus tested the new eight-seater helicopter from Eurocopter
for us, and in so doing he rediscovered much that was "well-known": the EC130,
which is positioned above the successful AS350 Ecureuil, contains a number of tried and
tested elements from other Eurocopter types, such as the EC135, the EC120 or the already
mentioned AS350. The "new" helicopter is being built in southern France and is
primarily aimed at the passenger transportation market.

EXHIBITIONS
NBAA Convention 2001
The Business Aviation sector was awash with optimism at its biggest gathering of the
year. Market analyses are predicting healthy sales in the longer term. Calmness was
evidently the predominant mood at the 2001 NBAA Convention in pre-Christmas New Orleans.
Those familiar with the biggest Business Aviation show in the world experienced once again
the friendly ambience and the well established programme, even if it was a smaller event
than planned. Originally scheduled for the third week in September 2001, the NBAA had
cancelled the exhibition in the wake of the shockwave caused by the terrorist attacks in
the USA and the drastic impact on aviation. After extensive consultation it took the
decision not to leave it at that, but to go ahead with the industry convention in December
despite scepticism in some quarters.

MAGAZINE
Extra Flugzeugbau: crisis under control?
For some months nothing but gloomy news, unofficial of course, has emerged from
Dinslaken-Schwarze Heide, headquarters of Extra Flugzeugbau. According to the rumours, the
company was in dire straits. It had run out of cash, and at times it even seemed that the
jobs of the 180 staff were on the line.
Now it seems that at least the financial crisis has been averted. The
workforce should be able to heave a sigh of relief. Their jobs are secure once more.
Helmut Giesers, a partner at Extra Flugzeugbau for over seven years, has once again
restored the company to its feet.
Another investor (and partner) who has been on board for a year now is
Tan Siekmann from Allendorf. Siekmann, an enthusiastic Extra-400 and CitationJet pilot,
made his money in e-commerce.
We researched in a fact-finding visit where the company will go from
here and what Walter Extras plans are for the near future.
Rotax six-cylinder 936
Development of the Rotax 6-cylinder 936 is progressing well. Flight trials will shortly
begin in a Piper Arrow. Remarkable progress in an engine that does not really exist, if
one asks Rotax. The Rotax engineers have already been working for several years on
development of this aero engine.
The project is known by the designation 936. Behind this is a
3-litre-plus, liquid-cooled six-cylinder fuel injection engine with reduction gearing. It
is planned to offer the V6 in a super lead-free turbo version and a normal lead-free
non-turbo version. The latter will produce 220hp at full throttle. The turbo version will
have the same power output, at least initially. However, it is likely that a significantly
more powerful version will come out soon afterwards.
The first 936 prototypes have been undergoing intensive bench running, including
vibration, temperature and full power tests, for some time now. Several different
propeller designs have also already been tested. The test engines have meanwhile
accumulated several thousand hours of testing.
FlightPlanner enhancement
It is now possible to plan the weather using the FlightPlanner 5.0 flight planning
program. German airfield data (AIP sheets) is available as an option.
The most important new feature of FlightPlanner 5.0 is the integration
of GAFOR into the flight planning, which was included in Service Release 9 that appeared
before Christmas. The program is based on as intuitive as possible flight planning using
ICAO maps, and now incorporates the weather in a practical and well organised manner. The
function can be used with a pc_met subscription to the German Meteorological Service
(DWD). At present it is even possible to gain access to GAFOR free of charge using the WAP
offerings of the DWD. All that is required for this is an internet connection.
In the cockpit with Gregor Gysi
According to his public image, the prominent PDS (Party of Democratic Socialism)
politician is clever, eloquent, dynamic, self-assured, aggressive, effervescent, at times
jittery. And as a pilot? "Peace and quiet are important to me," says the 53
year-old. He would not like to be at the aircraft controls when under time pressure as he
moves from one pre-election meeting to another.
But Gregor Gysi, who for many years was leader of the PDS
parliamentary party, first discovered flying through his work for the party. "From
1990," he recalls, "there would be appointments several times a year which just
could not be reached by any other means of transport."
Bonn/Hangelar: location factor for the region
For many years Bonn/Hangelar was surrounded by controversy. But things have quietened
down at last. Today no one doubts any more the importance of the airfield to the economic
region of Bonn.
Now the decision has to be taken as to whether Bonn/Hangelar will
be expanded in line with the new JAR OPS standards. Only if it is will the airfield be
able to continue its present function. Expansion would actually bring benefits with it to
the airports noise-sensitive neighbours.

TIPS FOR TRIPS
The Museo G. Caproni in Trent
Sometimes a really good destination for a possible outing will turn out to be quite
close at hand at least right next to ones travel route. The G. Caproni museum
at Trent airport in northern Italy is just such a destination.
For many tourists who drive down across the Brenner pass into "beautiful Italy"
Trent is a name that they probably know primarily from the motorway signs indicating the
appropriate motorway exits. Anyone who flies to Italy in greater comfort and more quickly
will find an outstandingly developed, little frequented airfield in the south of the city.

TRAVEL
All around Phoenix
Holiday in the USA combined with flying day excursions. Helga Kleisny discovered this
kind of travelling for herself. All around Phoenix, Arizona, she flew to numerous
interesting airfields in a chartered Cessna. There she experienced much in the way of
culture and curiosities as well as a wealth of flying impressions.

FLYING
Cessna 195
Two Cessna 195s on a small airfield, and a touch of rivalry is bound to creep in:
which owner has restored his aircraft the better, or which pilot flies the more beautiful
aircraft?
Tom Morriss "A" model from 1952 has green
stripes, while his colleague George Drays "B" model from the year 1954 has
red stripes. Both are lovely to behold and in excellent condition. Drays 195 won the
Lindbergh Award at last years Oshkosh for the best restoration, seeing off 31
rivals.

PRACTICE
Workshop test flight
Something that practically never occurs today used to be commonplace in MOT tests on
cars: the examiner would drive a standard distance with the vehicle to gain an additional
impression of its operational reliability. With aircraft it is different. Here the test
flight, known informally also as the workshop test flight, is in many cases a fixed part
of the programme.
Test flights are mandatory when it comes to the annual check,
after all major repair jobs and after significant modifications have been made to the
aircraft. On the other hand, it is relatively unusual to carry out a test flight after a
50-hr or 100-hr check.
We spoke to Karlheinz Bantle, Class I inspector at
Villingen-Schwenningen airfield, to find out exactly what gets checked on such a test
flight.
VASI and PAPI
Anyone who relies solely on his eyes during the final approach will soon end up wide of
the mark: the plane will be too high or it will practically shave the treetops on the edge
of the airfield. Especially for landings in unfamiliar airfields, PAPI and VASI are
invaluable indicators of the safe angle of approach to the touch-down zone.
Preparing for ones first solo flight
Preparing for exceptional situations in the circuit and during landing is part of basic
training. After that nothing more stands in the way of the first solo flight.
Things are looking up
When one is shutting down a helicopter turbine engine, why does one always have to wait
so long before one can switch the engine completely off? An engine specialist answered
this question for us and we have turned this into a practical contribution.
Accident analysis: approaching the pass at too low an altitude
Although the weather forecast was bad, the pilot took off in a Cessna in the vicinity
of Zurich, heading towards Locarno (Lago Maggiore). On the way he changed his course,
landed in a different airfield and then continued his flight towards St. Gotthard. In the
Reuss Valley he flew much too low, and moreover the aircraft appears to have been dragged
ever lower due to strong gusts of wind. The pilot realised too late that he had a problem,
but the engine was not powerful enough for a climb, and when he turned round he found
himself in the narrow valley. The dead body of the pilot was later recovered.

ULTRALIGHT
Weller Sprint: fabric and steel
The Sprint from Weller Flugzeugbau has a niche in the ultralight market. The two-seater
is not only available as a retrodesign. Its structure is also based on a 1930s type of
construction.
Here Weller offers solid craftsmanship. What the Sprint has to offer
and for whom this ultralight could be of interest you can read in detail in
Februarys edition of aerokurier.
New home for B & F at Speyer airfield
The first turf is expected to be dug for B & Fs new home before the month is
out. The manufacturer of the FK family of aircraft plans to move into the new complex at
Speyer airfield as early as the spring. It will then have around 900 m2 of
space available.

GLIDING
Werner Meuser wins World Champion title again!
On the tenth and last scoring day of the 27th Gliding World Championships in Mafikeng,
South Africa, Werner Meuser once again finished in first place in the Racing Class, flying
a Ventus 2ax. After a difficult start, the 49 year-old former World Champion of 1997 took
the title for the second time.
For some time it seemed unlikely that the German team, whose feats also
included a second place in the Open Class for Michael Sommer, would achieve such splendid
results. Instead, half-way through the competition it had seemed like a replay of another
title win, as Holger Karow, Open Class World Champion of 1999, having shot up from 11th
place to head of the table with a brilliant days win on the fourth scoring day, then
maintained this lead over four scoring flights. But shortly before the end of the World
Championships, he dropped back again, finally finishing in fifth place in his Nimbus 4M.
The potential of the German team was by no means exhausted with this
achievement. Instead of Karow, newcomer Michael Sommer (28), flying his first World
Championships, advanced right to the front. Consistently finishing ahead of the pack,
including two daily scores of second place, the ASW 22BLE pilot finished directly behind
the new Open Class World Champion, Oscar Goudriaan of South Africa (ASW 22BLE), and became
Vice World Champion.
On ones own: gliding safari to Lapland / Part II
A German team of three surveyed the thermals far to the north of the Arctic Circle this
summer. Using self-launching gliders, they flew across Sweden to Ivalo in the far north.
In Part II of this travelogue the three team members describe the return flight across
Finland.
Ultralight tow: crash shortly after take-off
Now that ultralight aircraft are allowed to tow gliders, a new risk must be borne in
mind for this type of take-off. Light ultralights generally lift off earlier than gliders,
and in fact a lot earlier if the glider is a heavy one with a rigid aerofoil profile.
Ultralight planes (like powered gliders) can then find themselves transitioning into the
climb when the glider has only reached minimum speed.
Sports sponsorship by the Bundeswehr
A lot of top pilots, members of national teams and German Champions around today have
something in common, namely they were sportsmen in the armed forces. They gained their
first successes with the Bundeswehr.
The Bundeswehr sponsors 700 sportsmen across the country. Eight of
these are qualified young glider pilots who every January take up service with the sports
company. Ahead of them are no less than eight exciting months in which the timetable is
dominated by gliding. The conscripts are stationed in Bückeburg, Lower Saxony. This
opportunity they owe to the present federal gliding instructor, Rainer Wienzek, who about
20 years ago succeeded in introducing sponsorship of gliding in the Bundeswehr thanks to
his good contacts with the Federal Ministry of Defence.
German-French youth camp
Whether it goes by the name of "vol à voile" or "Segelfliegen",
the important thing is the shared experiences in the air and on the ground at the
German-French youth distance flying camp at Klippeneck. And these were extremely positive.
Opinion: German Distance Gliding Championships to be split into two
Our popular sport is following an unusual route. The German Distance Gliding
Championships are to be split up into a German Championship and a European competition.
But the logic that determines which flights are to count for the German Championships is a
little odd, to say the least. Thus we are told that only the start or finish location or
one turning point need be in Germany, so that apart from one of the turning points the
entire flight can take place in a neighbouring country.
If this is the decision, the question then springs to mind: what is the
difference in the sporting sense between a holiday flight within Europe but outside
Germany which does not count for the German Championships and a "German" flight
that includes a take-off or landing in Germany but otherwise is flown entirely abroad and
yet counts for the German Championships?
If we are going to have German Distance Gliding Championships, then
please let us confine the qualifying flights to ones flown entirely within Germany.
SparrowHawk for UL gliders
A new all-carbon ultralight glider, the SparrowHawk, is being built by Windward
Performance in Oregon, USA. The prototype, built entirely as a carbonfibre pre-preg
construction, appeared without finish but entirely in black at its roll-out at the end of
last year.
The SparrowHawk was designed for good flying performance and simple
handling, so that beginners can cope with it as well. The best glide angle was calculated
with 33:1 at approx. 85km/h (46kt) and should also be better than 20:1 at 145km/h (78kt).
Maximum speed is specified at 228km/h (123kt).
The SparrowHawks empty weight is to be only 70kg (154lb) (!!) and its
gross weight 187kg (412lb). Its wing span is just 10.8m (35.4ft) with 6.3m2
(67.8ft2) wing area (aspect ratio 18.6). Minimum sink rate is 0.64m/s at
70.3km/h (38kt), minimum speed is 59km/h (32kt). The SparrowHawk is designed to withstand
loads of +5.48g and -4.0g.
