HYDERABAD: Now, Rajiv Gandhi International Airport (RGIA) has its entire Airfield Ground Lighting (AGL) signage converted from CFL (Compact Fluorescent Lamp) to LED (Light Emitting Diode) lamps.
A total of 132 units of AGL signage were converted from CFL to LED in a span of two weeks. More than 350 LED strips of 10W power were retrofitted to these signage. All these installations meet the mandatory regulatory requirement and maintain the required photometry level as per the operational needs. These signage are deployed across around 1,700 acres of the airside.
LEDs are known to be energy efficient. With the upgrade to energy-efficient LED signage, RGIA would save almost 45 percent of energy used over the conventional lights. The energy thus saved will reduce the airport’s dependency on traditional non-renewable sources of energy, slashing the greenhouse gas emission, which in this case translates to reduction of over 20,000 kg of CO2 per annum.
AGL signage acts as a guidance sign post to help pilots in identifying the location of their aircraft while at the airside and also while taxiing to the designated areas. There are typically two kinds of signage at the airside – mandatory instruction signage and information signage. Mandatory instruction signage has the inscription in white on a red background.
Information signage is provided where there is an operational need to identify a specific location, or routing (direction or destination) information.RGIA is operated by GMR Hyderabad International Airport Ltd (GHIAL).
