EDITORIAL
Veteran aircraft still going strong
The summer months are the peak season of the year as far as the owners of old aircraft
are concerned. They present their lovingly preserved gems at air shows and fly-ins and
meet up to exchange experiences with like-minded others. Pilots of veteran aircraft are
welcome guests at all the air shows.
These days the oldtimer community has a global organisation.
Internet and e-mail have been taken up gratefully by enthusiasts of veteran aircraft as a
means of speeding up the hunt for spare parts and maintenance tips. Anyone who performs a
search on the Internet will find thousands of home pages devoted to every conceivable
model of veteran aircraft. It just goes to show how up-to-date with the times the people
who spend a lot of time on old aircraft are.

FEATURE
Deutschlandflug 2001
Ninety years ago when the first Deutschlandflug was held in 1911 the reliability of the
technology was still the critical issue. Those days are long since past. Today the
emphasis in this big rally, which entails flying all over Germany and is organised every
two years by the Deutscher Aero Club, is on sports challenge and having a good time. This
year the objective was Wiener Neustadt, Austria.

PILOT REPORT
Piper Warrior with TAE diesel engine
Probably no Piper Warrior in the world has attracted as much public attention as
D-EPAT. From the outside the PA-28-161, built last year, looks no different from its
fellow stablemates of the same type. You would not guess from the noise it makes during
taxiing or flight that a quite special type of power plant is lurking in the engine
compartment. Rather, it is the stickers that arouse ones curiosity. "Powered by
diesel" they announce.
Delta-Alpha-Tango is the first Echo class aircraft to be fitted with
the 125hp TAE 125 diesel engine from Thielert Aircraft Engines. The four-seater low-wing
aircraft had only clocked up 60 flying hours when aerokurier got the opportunity to fly
along in it. On an excursion from Bonn to Donaueschingen we wanted to see what the
self-igniting plane would feel like in flight, what it is like to operate and what
aircraft performance it offers. To find out our impressions after the two-hour flight, see
the August edition of aerokurier.

AIR SHOWS
Paris Air Show 2001: surprise from Grob
The Paris Air Show is not renowned for its coverage of General Aviation. Nevertheless
surprises from the world of "small" aircraft do regularly occur at the
Aérosalon. This year it was the Grob company that provided the surprises. Grob Luft- und
Raumfahrt, which has expanded to employing a workforce of 160 and has gained impressive
international orders for the two-seater G115 and G120 aircraft, brought its latest
development, the G140TP, along to Paris. This is a four-seater plane with a retractable
undercarriage that is suitable for aerobatics and is offered both as a business aircraft
and as a trainer. It is powered by a Rolls-Royce 250-B17F turboprop engine which provides
a generous 450 shaft horsepower.
There were also new offerings from the French company sma. The
manufacturer of the SR305 diesel engine unveiled its TB20 prototype F-WWRS with series
standard engines and the final cowling design. Cirrus Design of Duluth, Minnesota is set
to take delivery of the first SR305 in September. Maule Air in Georgia has already
acquired a prototype for installation in a M-7.
Also making its debut in Paris was the TB20 Trinidad GT from Socata. This is
a limited version which has better avionics and offers more comfort.
Business Aviation holding up well
Business aviation is not immune to the vagaries of economic cycles either. But
fractional ownership programmes are ensuring that order books continue to bulge.
Helicopters in Le Bourget
The upgrading of air rescue organisations to new, more powerful helicopters and an air
race from Mont Blanc to Paris were the major highlights of the helicopter scene at the
Paris Air Show 2001.

MAGAZINE
Fuel-level indicator wins praise
When a scientist is also a pilot then he knows what aircrew really need. Hans-Jörg Dau
has invented a novel type of fuel-level indicator for powered aircraft, which won a prize
for innovation.
Academic exams plus pilots licence
They say that what you learn at school prepares one for life. At Rothenburg High School
in the Oberlausitz this means your future life as a pilot as well. Here teenagers can gain
a pilots licence in gliding, powered flight or ultralight, depending on interests,
before taking their school-leaving exams,.
Type rating on the Boeing 737
Holidays are the time to do something different, like skiing, for example. Or paddling
in the sea with ones children. Or gaining an FAA type rating on a powerful
twin-engined aircraft. Helga Kleisny describes what one can expect if one chooses this
kind of activity holiday. The type rating for the Boeing 737-200 costs $7,500. As such, it
is relatively cheap because the -200 variant comes without Flight Management System (FMS)
and without Electronic Flight Instrument System (EFIS). Training
takes two weeks, assuming that everything goes according to plan. However, many hours of
theoretical self preparation are required prior to the start of the course.
In the cockpit with... Mike Laux
He is one of the most successful aircraft salesmen in the world: in the course of his
career Mike Laux has found takers for over 450 aircraft, ranging from two-seater
single-engined planes through to luxuriously equipped business jets. Born in Remscheid,
Laux had originally envisaged a career as a designer. But his love of flying took him to
Ganderkesee where in the mid-1980s he acquired a shareholding in Atlas Air Service and
turned the company into the authorised German dealer for all Cessna aircraft.

TIPS FOR TRIPS
Excursion to Burgundy
Fancy a little excursion to France? Burgundy is practically on the doorstep from
Germany and has a lot to offer. Ludwig Haslbecks description of his trip to Beaune
will make you want to follow his example.

TRAVEL
Intercontinental flight with three single-engined aircraft
Seven people flew from Rheine in Westphalia to Fes in Morocco with two PA-28s and
one Cessna 172 between them. As spokesman for the party, Heinz-Josef Wiggers has written
an account of the trip. It turns out that a prominent role was played on the trip by the
white-green jellabah, an Arab garment that Wiggers purchased in Fes.

FLYING
Stinson L-5C "Sentinel"
Observation plane, liaison aircraft, air ambulance: the Stinson L-5 was a true
all-round talent. This is also underlined by the chequered history of the only aircraft of
the type to have been certified in Germany.
About a year ago Holger Braun came up with a "mad idea", as he puts it himself.
The 38 year-old, who has had a pilots licence for almost 20 years, succumbed to the
charms of a Stinson L-5C "Sentinel". "It had been on sale with a photo for
some time." Eventually he could resist no longer and bought the aircraft together
with an English partner. Today the Stinson which bears the identification D-EONH is based
at Schwenningen airfield.

PRACTICE
Fitness check for engine and airframe
Probably no means of transport is subject to such detailed technical monitoring as an
aircraft. During the 200-hour check on a Cessna 182 we looked over the shoulder of a
licensed aeronautical engineering business and take up the most important points.
The 200-hour check is also one of the more extensive checks in a
single-engined aircraft. Even so, in theory much of the maintenance work may be carried
out by the owner or another competent person, as long as the aircrafts MTOW is under
5.7 times and it is not used commercially.
What do you know about the chemistry of avgas?
Would you voluntarily pour a hydrocarbon mixture made out of paraffinic,
cycloparaffinic, aromatic and olefinic hydrocarbons into the tank of your expensive
aircraft?
Perhaps not spontaneously, but on closer examination you would, actually,
since from the chemical point of view that is exactly what avgas is. (Avgas = aviation
gasoline.)
VFR basic knowledge: maintaining heading and altitude
In the fourth in our "VFR basic knowledge" series we examine level flight.
Aspects covered include: controlling the engine, mixture control, straight-and-level
flight, climbing and descending, trimming, skidding, horizontal reference, gliding
distance.
Accident analysis: stall on approach to emergency landing field
The pilot had just left the mainland with two passengers on board and found himself
above the Oderhaff en route to Heringsdorf, when the engine of his Mooney M20 J cut out.
He decided to make an emergency landing on a nearby meadow that was surrounded by trees.
As he turned into the final approach the Mooney stalled, tipped over the right aerofoil
and crashed to the ground from an altitude of ten metres.

ULTRALIGHT
STOL della Italia: MXP-740 V Savannah
The Savannah is based on the STOL CH701. And yet it is quite different from the Zenair
STOL aircraft. We flew the Italian MXP-140 Savannah for you. Is it better than the
aircraft on which it is based?
"Flaps out, gas in and back with the control stick." That is
how we described, somewhat casually, the experience of a short take-off in the Zenith STOL
CH701 in aerokurier 11/98. We could almost begin in much the same way with the MXP-740 V
Savannah. With the CH701 it is much the same as with many other designs in the
experimental and ultralight scene: anything good catches on and sometimes is even improved
on. The Savannah is one of its derivatives, built by the Italian company ICP.
Borkum: first island open to ultralights
Ultralight aircraft are finally no longer excluded from flying to the
westernmost German island in the North Sea. The regional administration of Weser-Ems
granted Borkum airfield permission to operate with three axis-controlled ultralights in
May. Prior permission (a PPR) is required.
Ultralight glider meet at Wasserkuppe
Anyone who has no hesitation about wanting to experience a fly-in with a
difference will have the opportunity between 29 July and 5 August. During that week the
Deutscher Ultraleicht-Segelflugverband (German ultralight gliding association, DULSV) will
be holding its international convention for ultralight gliders on Wasserkuppe Mountain.
If experience is anything to go by, this annual event is
guaranteed to be an enjoyable experience. As well as the familiar ULF-1 ultralight gliders
and similar other planes, this year the Czech-built Banjo will be appearing for the first
time. Compared with ultralight gliders up to now, the one-seater with a glide ratio of 29
opens up a significantly wider performance spectrum. A Banjo was recently acquired by the
DULSV with donations and given to the Wasserkuppe Flying School. The flying school is the
first one in Germany where it is possible to obtain an ultralight glider pilots
licence.

GLIDING
World championships in Spain
In the 18m and world class sailing world championships, success eluded the German team
in a tight finish. On the penultimate day Bernd Gauger, flying an LS6-18w, was within
reach of the world championship title. Commercial pilot Bernd Gauger had already won the
pre-world championships 2000 in Lillo, a village with a population of 3,000 and a brand
new airfield, approximately 100km to the south of Madrid. And the prelude to the world
championships could not have gone any better: right on the first day he took the lead with
the best daily score. But then a bad tactical decision resulted in his slipping back to
11th place.
The first world championship in the 18m class was won by the
European racing class champion, Steven Jones, (Ventus 2cT) from the United Kingdom. In
second place was the standard class world champion of 1985, Leonardo Brigliadori (ASH
26e), followed by Werner Danz. Claus Triebel (DG-800S) came in fifth.
The world class title went to the Frenchman, Oliver Darroze. The
Germans, Axel Reich and Thomas Wartha, were seventh and eighth.
ETA: flying in the biggest glider around
With wings almost vertical the aircraft flies tight spirals through the sky. On board
the biggest glider in the world for the first time, gliding seems to have little in common
with ones previous experience.
For six hours Hans-Werner Grosse of Lübeck soared above the lakeland
area of Mecklenburg in the ETA. The performance is impressive even if the ETA is not yet
flying at full capability.
Block championships in Lüsse
Despite some adverse weather, contestants at the block championships for the 18m and
open classes at the beginning of June in Lüsse managed to glean five fiercely contested
competition days.
Club Class SPECIAL
The competition is only three years old and already an institution in the national club
class scene: the Club Class SPECIAL in Weissenburg. Judging by the field, Weissenburg can
now be compared with the German Championships.
Nagoldtal Cup
The newly introduced achievement badges in glider aerobatics have resulted in a
proliferation of medals at the Nagoldtal Cup. Six new club champions were picked out in
glider aerobatics.
Racing Class SPECIAL
There is now a "club class" for racing class aircraft of the first generation
as well. Immo Raithel 1 won the first ever Racing Class SPECIAL at Burg Feuerstein.
Gomolzig GO-100, capable of towing anything
At the Gomolzig Flugzeug- und Maschinenbau GmbH in Schwelm plans are
maturing for a glider tug which is intended to combine the advantages of powered gliders
and powered aircraft while avoiding their disadvantages. The company aims to develop a VLA
with a "hefty" engine that is specially tailored for towing. It plans to use the
SMA 230hp diesel engine that was certified in April, for which Gomolzig manufactures the
muffler. Peter Gomolzig estimates that the savings in fuel alone will have the effect of
reducing operating costs by one-third!
