The quality of illumination provided by LED lighting systems
can improve crew situation awareness by providing better visibility
during safety critical phases of operation, such as taxi,
takeoff and landing. " Focused beam patterns from LED wing
inspection lights also give the crew better visibility of the wing
leading edge during icing conditions. As a last point, it is relevant
to consider the empty weight and ESG since LED lighting systems
are typically lighter than the legacy lighting systems and reduced
empty weight improves the efficiency and carbon footprint of the
operation, " said Heads Up Technologies.
Cost-Benefit Analysis
The cost-benefit analysis for upgrading older lamps to newer LED
models in aircraft involves evaluating the costs associated with
the upgrade and comparing them to the potential benefits gained,
observed Fogel. " For this analysis it is necessary to first identify
the existing lamps, determine the types and number of lamps
currently installed in the aircraft, including their specifications,
such as wattage, lifespan and maintenance requirements, " he
affirmed. " Secondly, it is necessary to research and identify LED
lamp models that are suitable replacements for the existing lamps.
It is also important to assess the costs, including the purchase
and installation costs of the LED lamps and quantify the benefits
like the energy savings, longer lifespan, reduced maintenance
requirements, improved lighting quality, and potential weight
reduction due to the lighter LED lamps. "
The potential savings have to be calculated based on the identified
benefits, according to Fogel. " For example, the energy savings
should be estimated and the reduction in maintenance costs
based on the longer lifespan of the LED lamps calculated, " he said.
" Consequentially, the estimated savings should be compared with
the costs associated with the upgrade, this comparison will help
determine if the benefits outweigh the costs and if the upgrade
is financially viable. "
It is also important to consider additional factors that may
influence the decision, such as regulations or industry standards
and, finally, make an informed decision that should consider the
financial, operational and regulatory aspects, as well as the longterm
benefits that LED lamps can provide, affirmed Fogel. " It
is important to note that the specific cost-benefit analysis may
vary depending on the aircraft, the type of lamps being replaced,
and other individual factors. Additionally, it is key to consider
the potential risks and challenges associated with the upgrade.
These may include compatibility issues with the aircraft's electrical
system, the need for additional modifications or certifications,
and potential disruptions to operations during the installation
