Precision Approach

Question 1

What is a precision approach?

Answer 1

A precision approach provides both lateral and vertical guidance to a runway. Because of the addition of vertical guidance (the glide slope), the precision approach has the ability to get an aircraft closer to the ground than a non-precision approach.

Question 2

What does the ground equipment consist of?

Answer 2

The ground equipment consists of two highly directional transmitting systems, the localizer and the glideslope and, along the approach three or fewer marker beacons

Question 3

What three parts is the system divided into?

Answer 3

The system is divided functionally into three parts:
guidance information - Localizer, Glideslope
Range information - Marker Beacon, DME, Compass Locator
Visual information - Approach Lights, touchdown and centerline lights, runway lights

Question 4

Location of localizer and what it does

Answer 4

Far end of Runway
The localizer provides guidance to the runway centerline and it is located at the far end of the runway.

There’s a front and back course in the opposite direction. 3* width, 1.5 full deflection

Question 5

Location of glideslope and what it does

Answer 5

the transmitter is located on the approach end of the rwy, its usable distance is 10 nm. width is 1.4* full scale deflection is .7*
