Altimetry System Error (ASE) is a measure of the height-keeping performance of an aircraft. In airspace where the Reduced Vertical Separation Minimum (RVSM) is applied, the importance of accurate aircraft height-keeping is magnified. ASE is not detectible in routine operations; specialized measurement equipment is necessary to independently measure the errors. To be eligible for RVSM operations...

guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

Ernest P. Manly, W7LHL PO Box 1307 Graham, WA 98338-1307 [email protected] The selection of propagation modes for amateur microwave stations is often progressive. Most of us start with simple equipment and the contacts are usually by line-of-sight propagation. Longer distances are then accomplished by going to high locations. As equipment gets better, the use of various objects for reflection...

In aviation, aircraft ground handling defines the servicing of an aircraft while it is on the ground and (usually ) parked at a terminal gate of an airport. Ground handling operations include many activities: passenger handling, ground transport, assistance in blocking the aircraft and delivery of required equipment, loading and unloading of the aircraft, including provision and operation of re...

Maintenance management plays a key role in many industries, as maintenance determines the availability of systems, influences their lifespan, impacts customer satisfaction, and result affects overall investment profitability. In this context, aviation industry seeks models to improve efficiency. Researchers seek provide conceptual that help shape industry’s operations. Spare parts fundamental a...
