On the 8th of July Twente Airport played host to the annual Aircraft Owners and Pilots Association (AOPA) Fly In.
During this event, more than 100 aircraft found their way to Twente Airport, where they could enjoy lectures, an aviation market and a nice barbecue.
The excellent weather during the day made this a very enjoyable event. Twente had not seen that many visiting aircraft, since the last Royal Netherlands Airforce (KLu) Open House in 2003. This meant that all possible help was needed and provided.
Below is an impression of some of the visiting aircraft
During the first week of July the NLR (Netherlands Aerospace Centre) used Twente Airport to perform the first tests with the XCalibur+ Jet Trainer, a certified drone, according to the ASRPAS1 standards. The jet trainer is being used to gain experience on flying jet-powered drones.
The XCalibur+ jet trainer is based on a model aircraft, where several modifications have been applied to bring the aircraft onto ASRPAS1 specifications. The drone can fly on various speeds and is remotely piloted. It was the first time that the NLR flew this drone. Four NLR employees have been specially trained in Germany in order to fly jet powered, fixed wing, drones. Furthermore, the trials are supervised by a pilot with expertise on real jets and drone jets.
The experience gained with the jet trainer is essential for future NLR big drone activities. For some time, NLR has been working on the development of a large remote controlled jet plane measuring 4 meters in length and 4 meters span and weight over 100 kg. It does this within the framework of the EU Cleansky 2 SCALAIR (SCALed AIRcraft) project, in which a flying scale model of an existing airplane is being developed, built and tested. The purpose of this scale model is to show connection between the scale behavior of the scale model and the full-scale aircraft.
NLR chooses Twente Airport because this location is unique. ‘The NLR has the Netherlands RPAS Test Center (NRTC) in Marknesse, however, for the first flights with the jet trainer and other big drones, Twente Airport is chosen because of the availability of a long hardened runway, an obstacle free environment and relatively little air traffic. In addition, Technology Base, located at Twente Airport, offers the environment where innovative entrepreneurship and a lot of space to experiment together, “said Jan Willekens of NLR. Within the Dutch Drone Platform, NLR works closely with Space53 and the other proposed Drone test locations in the Netherlands to promote Drone development and use.
On the 27th of April 2017 AELS welcomed the first aircraft for disassembly at Twente Airport. On this date former Swiss Airlines A.340-600 HB-JMK arrived from Zürich. Many spectators were present at the Spotters Hill to witness this event.
At 10.36h, the A.340 made it’s last-ever landing at Twente. This was a unique moment for Twente Airport as well, since it was the largest aircraft to ever land here.
The Airbus with line number 169 is a 20 year old airframe, which made the last commercial flight from Johannesburg to Zurich on 24 April 2017. It started commercial service with Austrian Airlines and was later transferred to Swiss Airlines.
This is the first disassembly project that AELS carries out at Twente Airport. AELS has created a technical team that mostly consists of people from the region around Twente Airport. This team will carry out the disassembly of the aircraft.
Twente Airport has several good characteristics to dismantle a wide-body aircraft, which are beneficial for AELS. These are amongst others, a 2400m runway, sufficient platform and hangar space and the flexibility to host these types of aircraft.
It will take approximately 3 months to disassemble a complete Airbus. First the engines will be removed, after which all the useable parts will be parted out. Finally, the remains of the aircraft will be scrapped and recycled.
Since 2006, AELS has dismantled 50 aircraft, but this A.340-600 is the first wide-body aircraft. It is a large aircraft: approximately 64 meters in length, a wingspan of 60 meters and a height of 16 meters.
On Thursday 30 March 2017 Twente Airport was officially opened as a civilian airport. During a ceremony the authority was officially transferred from the Dutch Ministry of Defence to the Province of Overijssel.
More than 250 guests attended the ceremonies surrounding this transfer of authority, one of them was Sharon Dijksma, secretary of Infrastructure and Environment. In her speech she referrred to the pioneering powers for which the Twente region is well known. “Twente Airport will be a regional airport with regional characteristics and a national innovative agenda”.
Twente Airport will focus on 3 aspects of aviation: business and small aviation, testing and the settling of aviation related companies. This was already shown earlier with several tests that were executed at Twente Airport (see The Runway is Wet and NLR Tests at Twente Airport) and after the opening the NLR also announced that it would start testing large scale drones at Twente Airport. The settling of companies has also started with AELS. AELS is a company that specializes in the dismantling of aircraft and selling the reclaimed parts. They will use Twente Airport as a location to dismantle wide-body aircraft, such as the Airbus 340 and Boeing 747. The dismantling of aircraft like this takes approximately 2 months per airframe.
After a round-table discussion the moment came for Colonel J.P. Apon to officially transfer the authority to respresentative Eddy van Hijum. During this transfer the Koninklijke Luchtmacht said goodbye in a fitting way, two F-16’s made a fly-by over the runway that they had used for many years.
Airport Director Meiltje de Groot was hopefull for the future and commented: “The last couple of months we already received several requests to land at Twente Airport. Now we are really open for business! We already have several aircraft booked for the coming months and for example, the NLR will use Twente Airport to test their X-calibur drone.”
Earlier on the day several aircraft had already landed at Twente Airport to take part in the official opening. A special visit was made by a CH-47D Chinook from the Koninklijke Luchtmacht, it gave a small performance show for the spectators that had gathered on the Spotters Hill.
On 21 and 22 March 2017 Twente Airport hosted an Airbus A.400M to perform wet runway tests together with the Netherlands Aerospace Center (NLR). Niek van der Zande Photography was there to witness these tests.
The fact that Airbus would send an A.400M to Twente only became known to the outside world on Monday 20 March, when a NOTAM (NOtice To AirMen) was issued and the Grizzly was airborne out of the facty airport in Sevilla, Spain. Twente Airport already knew of these plans for a long time, but was not allowed to mention anything before.
Upon arrival in Twente, the crew first circled the airfield for a considerable time, as the crew was not yet sure whether the meteorological conditions were good enough for them to land. There are no ILS facilities in Twente, which means that conditions need to be good enough for a visual approach. Luckily, Twente Airport has its own meteo station on site, so the most accurate information could be passed on to the crew, after which they considered it safe to land.
The reason behind this unique visit is that Twente Airport has the facilities to perform wet runway tests, something that cannot be performed just anywhere. Twente has the unique situation that it has a long runway with the right surface. Next to that, the runway is prepared to create a water basin through which the aircraft can perform high speed taxi runs. In 2016 the first tests were already performed with a NLR Citation ( see: NLR tests at Twente Airport ), these tests were now performed on a larger scale. For this a set of grooves of 1cm wide and 3cm deep were cut into the runway. In these grooves large rubber slats were inserted so that a basin was created. This basin could be filled up with up to 3 centimeters of water, which resembles a heavy downpour of rain during a storm.
The A.400M then taxied through the water basin in order to measure the brake performance under various circumstances. IN order to get a clear picture, a total of 16 runs were executed, all at different speeds and with different braking profiles. The maximum speed at which the runs were performed was 110 knots, which guaranteed a big splash of water around the aircraft.
The tests themselves were initiated by the European Commission, in order get further information on aircraft performance under extreme conditions. These results will be used to further expand regulations and certifications and thus enhance the safety in aviation.
After this succesful series of tests, the A.400M left for Sevilla on Thursday 23 March. Twente Airport hopes to see more of these tests in the future, they are now talking to the Chinese manufacturer COMAC in order to see if tests with the COMAC C919 can be held at Twente Airport. This will get easier when ownership transfers from de Dutch Ministry of Defence to the Province of Overijssel on the 30th of March 2017. From then on the restrictions on the usage of the airfield will be lifted and visiting aircraft can be accepted at a 24 hours advance notice (24Hr PPR). This 24Hr PPR was introduced since the airport does not have a fixed staffing of Air Traffic Control, Fire Brigade etc. These will be hired on a need-be basis.
In order to facilitate operations outside of daylight hours, a GPS appraoch system will be introduced in the fall of 2017. This means that pilots can fly to and from the airport under Instrument Flying Rules (IFR).
The Netherlands Aerospace Centre (NLR) has chosen Twente Airport as the location of several tests with it’s airplane, a Cessna Citation businessjet.
On the 13th of September brake tests were held, whereby the runway was artificially soaked. The tests will continue on 15 and 16 September, but now brake tests will be performed in a water basin, which will be purposely built on a section of the runway. The NLR was looking for a location where some special tests could be executed; plenty of space and a runway with a special coating were required.
The top layer, Antiskid from the Possehl company, increases security when landing on a wet runway. These tests are held to measure exactly what the friction of the runway is in rainy conditions. The runway will be soaked with the use of six large tanker trailers that will spray a large amount of water on the runway. The testplane will then land shortly after.
On 15 and 16 September another set of braking tests were performed but now in a so-called waterbasin, that will be constructed on a part of the runway.
The amount of water in this basin represents the amount of water that can accumulate on the runway during a heavy downpour. The purpose of these tests is to see how the aircraft brakes perform in these extreme conditions. The knowledge that is gained will be used to adapt rules and regulations, which will then in turn increase flight safety. The tests on 15 and 16 September were performed in the light of a European study to increase flight safety.
The 1st of May 2016 was a historical date for Twente Airport with the arrival of the first commercial flight since 9 years.
With the departure of the Koninklijke Luchtmacht on 7 December 2007 military use of the airport ceased. As of 1 January 2008 the airport has been closed for civil aviation as well, pending governmental agreement on the future of the airport. On 16 June 2010 the province of Overijssel agreed on a spatial plan including an airport.
On 1 December 2010 the ownership of the airport grounds was transferred to the Twente region and the city of Enschede. Though it was attempted to find a party interested in operating the airport commercially, it was announced on 4 December 2012 that despite three parties showing interest in this proposal, none of them made a bid to operate it. In March of 2014 the government proposed that the airport could re-open for General Aviation users in 2015, and commercial traffic in 2016. Movements would be limited to 22.000 a year under the proposal primarily for noise abatement. However, in June of 2014 both the provincial government and the city of Enschede abandoned the plan to re-open the airport for commercial traffic. The future of the airport remained uncertain. In August 2015 it was announced that Belgian aircraft recycling firm Aeronextlife intended to start using the airport to scrap aircraft. As part of the plan, Aeronextlife would become responsible for the costs of certain vital services required for airport operation, such as a fire fighting presence during aircraft operations.
Besides the arrival of Boeing 737 aircraft for scrapping, additional traffic allowed at the airport include cargo aircraft to transport airplane parts, business charter aircraft of a number of operators that requested permission to use the airfield, a limited amount of smaller general aviation aircraft and gliders. Approval was granted, and flights to Twente Airport resumed one the first of May 2016 with the landing of Cessna Citation Sovereign PH-HGT, owned by ASL – Air Service Liège, coming from Manchester, which departed for Aosta later that day. Plenty of enthusiasts were present on the newly erected spotters hill to witness this historical moment.
On 24 and 25 April 2016 the U.S. President Barack Obama visited Hannover, Germany. The main purpose of his visit was to open the Hannover Messe but next to that he also had meetings with German Chancellor Angela Merkel, as well as with the Prime Ministers of France, Italy and the United Kingdom.
The pictures on this page were taken during President Obama’s arrival at Hannover Airport on 24 April and his departure on 25 April. Obviously there was a large number of security staff from both German and US authorities.
Between 28 September and 15 October 2015 the exercise Trial Embow 2015 was held at the range of WTD 91 in Meppen (Germany). This item gives some insight into the participants and purpose of the exercise.
The purpose of the Embow excercises is to familiarize aircrew with the self-defence tools that they carry against ground-based systems. The main aim of Embow is to allow aviators to test, under live and monitored conditions, the capacity of their aircraft to evade infrared-guided surface-to-air missiles, from basic Manpads to more advanced surface to air short-range systems (SHORADS). As a cherry on the cake, the Embow trials are always performed in highly instrumented areas so that the participants can take a close look at the actual efficiency of the systems they field. Any noticed discrepancy is then funneled, in a second move, back to the industry for updating and improvements.
For this year’s edition the WTD 91 range was chosen as the location. The range is the largest instrumented range in Europe and with dimensions of 7 by 31 kilometers and a reserved airspace up to an altitude of 5000 feet. Next to that the facility has its own airfield and helipad, which was very useful for the helicopters participating in the exercise.
Down on the Range
During a typical sortie, the range was booked for the duration of 30 minutes. Sorties were only flown by single aircraft, as the whole mission had to be measured. The aircraft would then fly a pre-determined set of patterns (radials) upon which a flare would be dropped after a count down from the ground station. These missions were also flown with different types of flares per aircraft type. Evaluation of the measurements would then show if the flare behaved in the same way as specified by the producer.
At the airfield
Trial Embow XV saw participation from all over Europe with various types of aircraft, ranging from a Belgian A.109 Helicopter to the British C-17 transport aircraft. Particpating countries were Belgium, Czech Republic, Denmark, Finland, France, Germany, Italy, Norway, Spain, Sweden, Switzerland, United Kingdom.
Most helicopters were temporarily based at Meppen’s airfield, whereas most fighters operated from Nörvenich and Leeuwarden airbases. Most transport aircraft flew directly form their homebase. Upon arrival at Meppen (EDR-34), they would change their normal radiocallsign to a callsign ranging from Outlaw01 to Outlaw10.
The Royal Netherlands Air Force Historical Flight Foundation, in Dutch ‘Stichting Koninklijke Luchtmacht Historische Vlucht’ (SKHV), was first started in 1969 as an aero club (Stichting Vliegsport Gilze-Rijen) by a group of former Air Force and Navy fighter pilots. The commander of the Gilze-Rijen Air Base at that time supported the renovation of a small hangar in which a Harvard and a Piper Super Cub were restored. The initial aim of this aero club was to provide private pilots with the possibility of advanced flying training. In the following years several historical aircraft were added to the fleet after having been carefully restored to an airworthy condition. From 1976 onwards the club has dedicated itself to the restoration and the maintenance of propeller-driven aircraft formerly used by the Royal Netherlands Air Force and Navy.
In 1998 the Stichting Vliegsport Gilze-Rijen and the Dutch Spitfire Flight merged to form the Royal Netherlands Air Force Historical Flight (SKHV) thereby bringing the only airworthy Dutch Spitfire and a Beaver into the collection. On September 24th 2004, during the 35th anniversary, the merge of the Duke of Brabant Air Force (DBAF) and the SKHV was announced. Since then the DBAF flag-ship, the B-25 Mitchell, has been part of the SKHV fleet.
During the past few decades the SKHV has grown into a leading aircraft museum with a unique collection of airworthy historical military propeller-driven aircraft. The professional and enthusiastic contributions of the many volunteers and the co-operation with the RNLAF ((Royal Netherlands Air Force) is the sound basis of its existence.
The SKHV has contributed to the making of several feature films, such as A Bridge Too Far, Soldaat van Oranje, De Aanslag, the musical Joe and the film Zwartboek directed by Paul Verhoeven. Various SKHV aircraft and participants appear in these films. The SKHV is also a regular participant in air shows in the Netherlands and abroad.
The Spitfire and the Mitchell but also various other types of aircraft are shown.
The SKHV organises aviation events giving the spectators the opportunity to be introduced to historical aviation. An elucidation of aviation history, the sight of formation flights, and the smell and sound of droning engines often leaves behind an indelible impression, and a flight in one of the historical planes is invariably perceived as a unique experience.
