There are technologies being discussed to improve crash tracking technologies. These are ULB battery life improvements, an additional low frequency ULB. Another technology is ADS-B which monitors the position of the aircraft. Deployable flight recorders in the event of an accident and streaming of flight data via a satellite are also being considered. Let's take a closer look at each technology. Numerous improvements to ULB technology are underway. ULB battery life is about to be extended from 30 days to 90 days. There will be an additional ULB attached to the fuselage which will transmit at a lower frequency which will increase the audible range of the beacon. In light of the MH370 tragedy and the lingering doubt as to whether the ULB heard was the ULB attached to the aircraft, I suspect we will see a simple identifying code such as a serial number added to a ULB's sound waveform, which would not be technically difficult. Unfortunately the 90 day battery requirement will go into effect in March 2015 and the requirement for the low frequency fuselage attached ULB will go into effect in 2018. Additionally, current regulations do not require the upgrade, so considering a lifetime of 6 years in the last 30 Daily ULB may not be replaced until 2021. The cost of upgrading to a 90 day battery due to special transportation rules that add to the expense of this upgrade (Federal Aviation Administration). While progress is being made in this area, it will occur at a slow pace. Furthermore, nothing is being done to improve the survival or quality of the ULB project. The Future Air Navigation System (FANS) and ADS-B are systems in which commercial aircraft transmit identification, current position, heading, altitude and speed,... ... middle of paper ......014. .The Boeing company.
