Flight Helicopter

The Military Coordination Center (MCC) monitored conditions in the security zone and had operational control of Eagle Flight helicopters (the Black Hawks), which provided general aviation support to the MCC and the CTF. 

Russian-American aeronautical engineer Igor Sikorsky makes the first successful tethered helicopter flight. 

The inability of the engine to produce a useful propulsive force at zero or low flight speeds necessitates the use of an auxiliary power plant to initially accelerate the vehicle to the required take-over speed of the ramjet. Such auxiliary power is also required for controlled landing of the vehicle. As a consequence the ramjet engine is not well-suited for conventional aircraft applications (with the exception of the helicopter) and the principal application of the engine appears to be further restricted to missiles or other similar vehicles of a one-flight expendable nature ...

These results were later confirmed in an actual in-flight study in which 10 pilots completed a series of 1-hr flights in a specially-instrumented UH-60 helicopter throughout 40 hr of continuous wakefulness (180). When 10-mg doses of dextroamphetamine were given at midnight, 04 00, and 08 00, the performance...

Dispersants are applied either neat (undiluted) or diluted in sea water. Aerial spraying, which is done from small and large fixed-wing aircraft as well as from helicopters, is the most popular application method. Spray systems on small aircraft used to spray pesticides on crops can be modified to spray dispersant. Such aircraft can perform many flights in one day and in many different conditions. Their capac-...

Chapters 5 and 6 are devoted to problems which could be understood most easily by applying the energy balance, and this chapter is devoted to other problems, which could be understood most easily by applying the momentum balance. Some problems are most easily understood by applying both the energy and th momentum balances. A very interesting example is the elementary analysis of flight, which helps explain the behavior of airplanes and helicopters and birds and insects.

The MIDAS system has evolved over a period of 15 years of development (Corker and Smith 1992). The basic structure of the core system presented here is based on the work of Tyler et al. (1998). This architectural version of MIDAS has throughout its development been used to evrduate helicopter crew stations, short-haul civil tiltrotor emeigency handling operations, tmd the impact of MOPP flight gear on crew performance (Atendo et al. 1996, 1998 Shively et td. 1995). The spedfic development for analysis of air traffic management systems will be provided below.

Each study employed a variety of related assessments. In the dextroamphetamine and triazolam studies, flight performance was objectively measured by eomputer in a UH-60 helicopter simulator or aircraft while subjects flew a standardized course central nervous system (CNS) function was measured ly a resting eyes-open/eyes-closed electroencephalograph (EEG) mood and/or sleepiness were measured by self-report instruments such as the Profile of Mood States (POMS) or the Stanford Sleepiness Scale and vigilance and cognition were measured with the Walter Reed Performance Assessment Battery (PAB), the Synthetic Work Battery (SYNWORK), or the Multi-Attribute Task Battery (MATE). 

To address these concerns, lOUH-60 pilots were exposed to 1 week oftesting that included two separate40-hourperiodsofcontinuous wakefulness very similar to those used in the earlier simulator study. Subjects completed flights in a specially instrumented UH-60 helicopter, as well as electroencephalographic, cognitive, and mood tests. During one deprivation period, subjects received three separate 10-mg doses of dextroamphetamine 1 hour prior to each of the...
