Interpretation of High Altitude Instrument Approach Plates
T-45A UJPT & E2-C2 INav-07
j.
Closed runways/taxiways
k.
Location/identification of buildings, control tower, airport
beacon, and other structures
l.
True/magnetic north orientation, date, and annual rate of
change - True/magnetic North orientation may vary from
diagram to diagram, i.e., North may not be at the top of the
page
m. Location/elevation of obstructions
n. Geographical coordinate grid - Coordinate values are shown in
1- or 1/2-minute increments. They are further broken down into
6-second ticks, within each 1-minute increment
o. Runway weight-bearing capacity
C. Instrument approach minimums section 2.9.4.1.1
1. Type of approach
a. Straight-in/circling/side-step
b. Precision/nonprecision
2. Aircraft approach speed determines the aircraft's category
a.. A,B,C,D,E, and copter
b. Generally, only categories C, D, and E are listed in high altitude
terminal approach plates (T-45A falls under C). Occasionally
category B is listed
3. Ceiling and visibility requirements - criteria used for IFR destination
and alternate filing purposes. Also establishes takeoff criteria
a. Ceiling in feet above ground level (AGL)
b. Prevailing visibility in statute miles (sm)
c.
Runway Visual Range (RVR) in hundreds of feet (if airport is so
equipped)
NOTE: To convert RVR values to mile or metric equivalents,
refer to the METAR Conversion Chart near the front of each
FLIP (Terminal) high altitude approach publication.
