ILS Course 15441921

DESCRIPTION

This 10-day course is designed for international participants as an introductory, instructor-led training course for technicians, engineers, and developmental technicians on Instrument Landing Systems (ILS) concepts. Concepts covered throughout the lecture include ILS, glide slope and localizer theories. This course will prepare participants to be successful in ensuing equipment courses and in obtaining a conceptual understanding of the operational principles of an ILS system. Subject matter may be modified to meet unique customer needs by special agreement.

OBJECTIVES

At the conclusion of the course, participants will be able to successfully:

• Identify the functions, operating frequencies, and general locations for the ILS subsystem.
• Explain modulation and demodulation principles.
• Utilize concepts and terms related to ILS subsystems.
• Explain the effects of changes in antenna phase, separation, and current magnitude has on radiation patterns.
• Identify signals when looking at antenna feedlines, indicating waveforms and RF phases.
• Calculate effective space modulation by combining the carrier and sideband voltages in phase and mis phased.
• When given a simplified block diagram, identify the signals and the effects of sideband amplitude has on the ILS receiver.
• Calculate within + 0.1 degree, the elevation angles of all critical points given the glideslope antenna heights.
• Calculate and sketch DDM at any elevation angle up to five times the glide angle.
• Describe the null reference glideslope array proximity errors, the causes, and the methods used to compensate for it.
• Determine phase error within + 5 degrees at any point using quadrature phasing theory given the phaser change.
• Identify the minimum distance from threshold for a localizer antenna array.
• Identify the purpose of each component in a monitor circuit.
• Identify types and priorities of the different types of flight inspections.

WHO SHOULD ATTEND

Participants will be required to be proficient in basic algebra, as well as performing computations on a scientific calculator. Knowledge of basic electrical and electronics theory and components is expected.
