Here are Ole´s Stories
Hi, I´m Ole. Since Induperm A/S was founded in 1969, I have been involved in the supply of airfield lighting equipment to airports all over the world. The different fields led to great memories and friendships. I would like to tell you some of my personal stories.
Our first major Induperm contract in Africa
In the middle of the 1970s, the small country Malawi was almost isolated between not very friendly neighbors, and without direct access to a harbor, therefore, the country was very much dependent on supplies by air. However, the new airport in the capital city of Lilongwe was delayed due to financing problems and the only airport in use, Chileka Airport, was only with a non-category and very poorly maintained AGL system.Read moreRead less
Induperm A/S was requested to perform a survey and come up with a project suggestion to update Chileka Airport to Cat.1, whilst keeping the airport operational during the project phase.
Induperm A/S was awarded the contract for the design, supply of equipment, installation, training and commissioning.
For the on-site work, two Danish engineers were in Chileka for approx. 6 months, an additional sixty local workers were hired during the installation phase.
Before the supply, three technicians from Malawi visited Denmark for training for an eight-week period. Each of the technicians was trained to take over the responsibility for a certain technical area, such as electronics (Remote control and CCR), light fixtures and ground parts (cable, joints and isolating transformers).
All necessary equipment (including 80 km high voltage cable, 20m poles in 6m sections) was shipped in six 20” containers.
Malawi was a very poor country, but the people are extremely friendly and very helpful. The job was completed on time and, during subsequent visits, we could see that the Malawi technicians are capable in maintaining the system in the best way.
The first important steps in Greenland
For many years all airtraffic in Greenland was based on helicopters, except for a handful of traditional airports. Helicopter traffic is very expensive and sensitive to bad weatherconditions. On the other hand, it is very difficult and expensive,sometimes even impossible, to find a suitable terrain for a traditional runway.
In 1980 it was decided to build the first STOL (Short Take Off and Landing) with an AGL system according to ICAO STOL standards.
A STOL airport has a very short runway (typicallyfrom 800m to 1200m), a short approach light system (but with side row lights), and a much steeper landing angle than normal (typical 6°instead of 3°).
The requirements for the light fixtures were typically wider main beam and steeper light angles.
Such light fixtures were not available on the market at that time, and Induperm won the contract to develop this range of fixtures and supply the complete AGL system for Jacobshavn Airport, now Ilullisat Airport.
Our initial project in Switzerland
In the middle of the 1970s, a new runway, 14-32, was established as an (almost) parallel runway to the existing runway 16-34 in Zurich
For the first time, the series system was selected for the AGL system. Induperm was awarded the contract for the supply of Thyristor-based Constant Current Regulators and a large number of isolating transformers.
The installed AGL system was state of the art with light intensity levels well above the ICAO minimum values.
The first landing was a Jumbo jet (Boing 747) from SwissAir arriving from US. For this event, a number of VIPswere invited to watch the landing from a position in the approach area. A provisional command center, with a golden push button for switch-on, and blue / red push buttons for intensity control was established.
On the picture two young engineers can be seen testing the control center (Alfred Seiterle, Aeroplan and Ole Lund-Hermansen, Induperm).
The system was put into operation in 1976.
The two young engineers are still good friends and still feel young inside!
Induperm as first mover on PAPI installations
In the late 1970’ties a new idea of another visual approach aid system was revealed from Great Britain. It was called the PAPI system (Precision Approach Path Indicator).
Long before it was official approved, Induperm realized the potential behind the idea, and Induperm started development of the necessary PAPI units in 1977. The first test installation was set-up in Esbjerg Airport in Denmark, to create operational data for an official approval.
In the late 1970s a new idea for an alternative visual approach aid system was introduced from Great Britain. It was called the PAPI system (Precision Approach Path Indicator).
Long before it was officially approved, Induperm realized the potential behind the idea, and Induperm started development of the necessary PAPI units in 1977. The first test installation was set-up in Esbjerg Airport in Denmark, in order to create operational data for an official approval.
The test set-up in Esbjerg consisted of a conventional VASIS installation on one side of the runway, and a PAPI installation on the other side. The accuracy in the approach path was monitored for both aircrafts using the VASIS system and the PAPI system.
The results were very clear. The pilots were satisfied with the PAPI’s visual harmonization with the ILS, and the reduced number of flight angle corrections during the approach.
Below a picture from the test set-up:
