Q-Helipad Hapi System

Details

HAPI (helicopter approach path indicator) systems (Q-HAPI system) provides the necessary visual information to place the helicopter on the ideal approach slope path. Pilots can easily determine if their approach is too high, too low, or correctly on slope through combinations of red and green lights. The Q-HAPI is available in three basic models with multiple configuration options to comply to ICAO requirements.

The Q-HAPI consists of a single lighting to provide a visual indication of the correct approaching path of the helicopter . In compliance with ICAO requirements, the Q -HAPI is located adjacent to the nominal aiming point and aligned with the preferred approach directions. The angle of elevations setting of the Q -HAPI is easy to adjust by the build in monitor showing the actual angle. The Q -HAPI is below 25 cm and it is therefore approved for all helidecks installations, forming no obstruction for the helicopter. Each flight approach path is required to have a HAPI system.

A) This product must be connected to the Q72RI03C – Q-HAPI control system. The Controller is sold separately.
B) When a complete helideck/heliport package is offered, the Status Light Controller can be built-in the Q-Control X series.

The Q-HAPI is a lighting unit which emits four distinct types of light:

1. Flashing Green Light = Helicopter above the optimal approach slope (too high)
2. Fix Green Light = Helicopter on the slope
3. Fix Red Light = Helicopter slightly below the optimal slope (slightly too low)
4. Flashing Red Light = Helicopter below the optimal slope (too low)

The signal repetition rate of the flashing sectors must be greater than 2 Hz.
In accordance with ICAO, the HAPI is capable of adjustment in elevation at any desired angle between 1 and 12 degrees above the horizontal with an accuracy of +/- 5 minutes of arc. The Q-HAPI will switch off atomically when the vertical misalignment of a unit exceeds ±0.5 degrees (±30 minutes).

OFFSHORE / ONSHORE USAGE

In compliance with ICAO requirements, the Q -HAPI must be located adjacent to the nominal aiming point and aligned in line with the preferred approach directions. The angle of elevations setting of the Q -HAPI must be such that, during approach, the pilot of the helicopter observing the upper boundary of the “below slope” signal (flashing red) clears all objects in the approach area by a safe margin.
