8. INSTALLATION, INTEGRATION AND CHECKOUT
8.1 Introduction
This section contains the information required to install the equipment, inspect the installation, perform startup and
preliminary testing procedures, and perform an installation verification test.
8.2 Site Information
The Marker Beacons are located along the extended runway centerline to provide a rough indication of an aircraft's
distance from the runway threshold, and to indicate significant points along an instrument approach path.
An Outer Marker is typically located 4 nautical miles from the runway threshold; this location normally coincides with the
point on the Marker Beacon approach at which the glide slope altitude equals the intercept altitude. A Middle Marker is
typically located 3500 feet from the runway threshold; this location normally coincides with the point on the glide path at
which the decision height (DH) is located for Category I operations--200 feet above the touchdown zone elevation.
A typical Marker Beacon site plan is illustrated in Figure 8-1. This illustration shows the shelter and tower foundation
locations, trenching details, and site preparation requirements. The terrain around the Marker Beacon site is to be graded
to the specifications of FAA Order 6750.16B, Siting Criteria for Instrument Landing Systems, or as determined by the
siting engineer.
8.3 Unpacking and Repacking
Packing cases are to be handled and opened with care to avoid damage to electronics components. Be certain all
fasteners, supports, and tie-downs have been removed before attempting to remove the units. Inspect all items for ship-
ping damage and check against the packing slip to ensure complete shipment. Check the packing slip against Table 1-2.
