Helicopter wire strike protection and prevention devices: Review, challenges, and recommendations

Evaluation of existing technologies designed for helicopter against wire-strike

“…The system can be deployed for missions conducted at nighttime. The cost of PDS is estimated at around $12,500 (Chandrasekaran et al, 2020).…”

“…One of their benefits is that there is no installation needed on aircraft for use. The cost of installing systems is estimated at around $50,000 (Chandrasekaran et al, 2020). One of the disadvantages is that these systems are only installed in designated areas.…”

“…Current WSPS fit well on larger helicopter models, but their installation on lightweight aircraft (Chandrasekaran et al, 2020) can be a challenge due to their airframe structures, and also their effectiveness is questionable.…”

“…As defined by FAA, an EFB is an electronic system designed mainly for flight deck use ( Yeh, M., & Chandra, D. C., 2007). The EFBs provide a pilot with all information needed, such as aeronautical charts, maps, VFR and IFR route charts, flight documents, and more, in "digital format" (Chandrasekaran et al, 2020). EFB system is able to store all this information on one portable device, e.g., a mobile or a tablet.…”

“…Some systems can stand alone, while others can be integrated into aircraft avionics. The price of EFBs is approximately $500 to $25,000 (Chandrasekaran et al, 2020). Just like HTAWS, EFBs require obstacles information in order to alert a pilot of any threat along the flight path.…”
