in order to decrease the risks associated with the management of urban watersheds, the use of proper methods is an essential task to estimate the runoff with a high degree of confidence. time of concentration is one of factors that impacts on peak discharge and runoff volume. the objective of this study is to select the best method among the empirical formulas for estimating the time of concent...

The study, by the U.S. Federal Aviation Administration (FAA) Civil Aeromedical Institute (CAMI) in Oklahoma City, Oklahoma, found that one such personal computer (PC)–based simulator “can be a useful and economical tool for examining experimental questions involving general aviation pilotage,” despite some minor drawbacks. Although this study examined the uses of PCs and standard software for g...

This report is the 4th in a series of joint ATM operational performance comparisons between the US and Europe. Building on established operational key performance indicators, the goal of the joint study conducted by the Federal Aviation Administration (FAA) and EUROCONTROL on behalf of the European Union is to understand differences between the two ATM systems in order to further optimise ATM p...

www.mathworks.com The purpose of RTCA/DO-254 (referred to herein as “DO-254”) is to provide guidance for the development of airborne electronic hardware. The Federal Aviation Administration (FAA), European Aviation Safety Agency (EASA), and other worldwide aviation safety authorities require this standard to ensure that complex electronic hardware used in aircraft systems works as specified und...

Distance Measuring Equipment (DME) is seeing renewed interest for its ability to support future aviation navigation and surveillance needs. It is one of the primary technologies being examined by the Federal Aviation Administration (FAA) Alternative Positioning, Navigation and Timing (APNT) project to support needs to provide an alternative to global navigation satellite systems (GNSS) in the N...

Current concerns about persistent visual abnormalities after the use of isotretinoin may lead the Federal Aviation Administration to further restrict its use in pilots or future pilots.
