Landing lights are used in night landing operations by aircrafts. Position lights are also known as navigation lights. These lights are placed on the wingtip (red on left wingtip, green on right wing tip) and on the tail of the aircraft. Anti-collision lights illuminate the important parts of the aircraft. These lights are placed at the rudder (vertical tail of the aircraft), fuselage (body of the aircraft), and on the wingtip of the aircraft. A red beacon is used on the rudder whereas white strobes are used on the wingtips. Cockpit lights assist the pilots to view the important switches and instruments. Cabin lights are used to illuminate the aircraft cabin. Emergency lights include interior and exterior lights, which are battery powered. They are not directly connected to the main electrical system of the aircraft.

A UAV payload includes the objects carried on a UAV which are used to make the UAV efficient and versatile. Electro-optic cameras that can take real-time video of objects in the visible light spectrum are an example of a UAV payload. UAV payload also includes lasers that provide light at night for viewing and targeting an object. SARs that use a single antenna to generate accurate radar imaging of target places, signal intelligence sensors used to locate, detect, and classify radio frequency transmissions, and electronic warfare equipment used to locate, detect, and classify radar emitters are some of the other examples of UAV payload. UAV payload is controlled by ground control units, which include command, control, communication, computers, and intelligence systems. Such units are used to collect data and make it available to different departments of the intelligence system of a country through integrated surface routers.

This report covers the present scenario and the growth prospects of the Global UAV market for the period 2012-2016. The market size is based on the sale of UAVs to the DODs of various countries. To calculate the market size, the report considers the revenue and unit sales of the different segments of the Global UAV market such as Mini-UAV, Small Tactical UAV, Tactical UAV, Naval UAV, MALE UAV, HALE UAV, Uninhabited Combat Air Vehicle, and Civil Small UAV. The report also presents the vendor landscape and a corresponding detailed analysis of the top four vendors in the Global UAV market. In addition, the report discusses the major drivers that influence the growth of the Global UAV market. It also outlines the challenges faced by the vendors and the market at large, as well as the key trends that are emerging in the market.

The objectives of the study were to use finite element computer modeling to investigate the behavior of Wisconsin W wide-flanged prestressed girder ends during and immediately following the strand detensioning process, and to identify solutions for controlling girder end cracking by reducing concrete tension strain or introducing sufficient reinforcement to keep concrete tension strains low and crack width limited.
