HVLAS – Helicopter Visual Landing Aid System

The Helicopter Visual Landing Aid System (HVLAS) is a flexible modular design to match customized HVLAS requirements for all needs, all helicopter types and all operating modes (NVG Stage III, HIFR, VERTREP, etc.) including LED Glide Path Indicators, LED Horizon Reference Systems, LED Flood Lights as well as LED Flight Deck Lighting. For operation, the system is completed by Lighting Control Panels with optional touch panel to monitor aviation weather, ship movement and wind limitations as well as to control helideck equipment (e.g. Refuelling, GPU and Fire Fighting). This Helicopter Integrated Monitoring & Control System (HCIMCS) offers a complete comprehensive NVG-compatible helideck system solution and is developed on a turnkey basis meeting various customer requirements.
Helidecks, whether on ships or offshore platforms, are exposed to extreme environmental conditions. Seawater, enormously high wind speeds and intense sunlight making high demands on the landing platforms and also on the safety of crews and pilots. A Visual Landing Aids System basically consists on a modular system conformed of state of the art components. This modular system enables various configurations for different requests on naval and civil vessels.

Different areas on the ship require special demands for lighting

HVLAS components meet the challenging physical requirements due to the military environmental conditions, operational areas (Tropic, Arctic and Antarctic Sea) and Flight Safety First policies. The system is designed to provide illumination, optical references and signal indication during helicopter operations on the helicopter flight deck of seagoing vessels.

Important factors when working with lighting solutions for helidecks are:

  • High range for the Glide Path Indicator (>5 NM) and exact light distribution due to the use of latest LED Technology and high precision optics
  • Complete NVG compatible
  • Two modes of operation for the complete system (NVG-mode, Normal-mode)
  • High brightness due to LED technology for safe daylight and bad weather operation
  • Outside mounting due to non-corrosive antimagnetic materials
  • Radar cross section reduced
  • Proved according to the latest relevant shipbuilding and aviation standards
  • Long lifetime
  • Extremely low lifetime costs due to LED technology
  • Low mounting and cabling costs due to an integrated system
  • Integrated system for all flight deck operations
  • Easy exchange of single components due to a modular system
  • Minimized maintenance costs and reduced power consumption (high energy efficiency)
  • Mechanical strength/impact resistance.

Mechanical strength

The development of lighting solutions for helidecks represents a huge challenge in terms of mechanical, electrical and lighting technology. It means that the products have to be extremely robust and must function absolutely reliably across a temperature range from -25°C to +45°C. Maintenance-free LED technology ensures that lights have a long and reliable lifecycle. Due to their use in extreme environmental conditions, helideck lighting products have to be robust and durable in many aspects: they must be UV-resistant. The housing should be made from seawater-resistant aluminium. This sensitive technology has to be fully vibration-proof. An IP rate of IP 66/67 is recommended for products installed on exposed positions like e.g. helideck.  

No maintenance and reduced power consumption

An important requirement on-board a marine vessel is to install luminaires that are virtually maintenance-free. This reduces or eliminates labour costs, primarily associated with the maintenance, servicing and replacement of luminaires in difficult-to-reach locations with either poor access or often no access at all. The luminaires should consume as little energy as possible in order to reduce the size of power generators, save energy and minimise pollution. The efficiency and life span of LED lighting continues to improve. LED luminaires are virtually maintenance-free, which means that vessels with LED lighting will have lower operating costs compared to vessels with conventional luminaires. The initial investment of the LED installation may be higher than a traditional lighting installation, but the LED’s reduced energy consumption and lower maintenance costs means that this price difference will be quickly recouped and payback on the investment is recovered quickly.


Lighting solutions have to be in fully compliance with the relevant international standards such as ICAO Annex 14 Vol. II, an International Civil Aviation Organization guideline to improve the safety of helicopter crews during take-off and landing.  Lighting also has to comply with the Civil Aviation Authority (CAA) standards CAP 437 and CAP 168. The HVLA System is designed to meet the highest military standards for flight safety in maritime environments for Naval and civil use.
