Chapter 2: APPLICATION CRITERIA
2-1
PURPOSE OF CHAPTER
This chapter provides application criteria to ensure that the installation of visual air
navigation facilities is appropriate for its intended purpose and that it is sufficient to
achieve the desired level of operation.
2-2
RELATION TO ELECTRONIC FACILITIES
Except for VFR operation, electronic facilities are required to provide initial positioning
and direction information to an approaching aircraft. Visual air navigation aids are
required to ensure a timely and safe transition from the instrument phase of an
approach to its visual phase. The planned operational level for an instrument runway
can only be achieved through a combination of appropriate electronic and visual
guidance systems. Failure to include required visual aids in the planning of an
instrument runway will degrade the utility of the electronic systems. Conversely,
enhancing of a runway with inappropriate visual aids will waste resources with little
operational advantage.
2-3
APPLICATION OF REQUIREMENTS
Use the application criteria in this chapter for planning, budgeting, and installing visual
air navigation facilities. Do not initiate the addition or upgrading of visual aids to a higher
order of operational requirement unless the runway, taxiway, or helipad has been
officially approved for the new level of operation and appropriate electronic aids have
been installed or are programmed for installation. Waivers are required for all deviations
in accordance paragraph 1-10 or 1-11, as applicable.
2-4
MATRIX OF REQUIREMENTS
The matrix of requirements for Air Force airfields is shown in Table 2-1A. and for US
Army airfields is shown in Table 2-1B. The matrix of requirements for helipads/heliports
is shown in Table 2-2. Each matrix contains application criteria for operational
categories and the related visual aid requirements.
2-4.1
Not Required (NR) designates a visual aid which is not required for a
particular operation and is therefore not specifically provided to support it.
2-4.2
Not Applicable (NA) designates a visual aid whose operational
performance is not adequate to support a particular operation or where a particular
operation that could be supported is not required.
