Designed to the same outline as a low altitude approach plate, for aircraft penetrating the high altitude enroute structure to land during instrument conditions
Pilot Briefing and Procedure Notes:
HI-TACAN 24R, Miramar
Includes NAVAIDs required and the final approach course with limited airport information for quick reference
Notes referencing the approach as a whole will be included
Approach light systems will be labeled and depicted
Missed approach instructions are published in text
Types of radar coverage available (ASR/PAR)
Frequencies for:
ATIS
Approach
Any headings listed for different frequencies are based on your heading TO the airport
Example: Heading 270 a note 360-200 would mean you do NOT use that one while a 200-360 would be the correct frequency
Plan View:
20-mile radius circle around the navigation facility features encircled by bold print line are to scale
Feeders will be included when able but normally won't be to scale, expect a radial and DME
Used mostly to orient one remote NAVAID to another
The terrain within 6 NM of airfield rises to at least 2,000' above airfield elevation
The terrain within the plan-view "to scale" area exceeds 4,000' above the airport elevation
Four basic penetration patterns:
Straight-in
Offset
Arcing
Teardrop
Holding Patterns:
Used until you are cleared to proceed beyond the IAF onto the approach
Thin solid line with notations indicate arrival holding
Holding in lieu of a procedure turn is NOT depicted on high altitude approach plates
Entry diagram found on the upper right corner of plan view to assist with entry
Missed approach holding patterns are depicted the same as the route
Obstacles:
All obstacles are referenced from Mean Sea Level (MSL)
Single: inverted V with elevation in feet
Group: two overlapping inverted Vs with elevation in feet
Highest: large inverted V with elevation in feet
Spot Elevation:
All elevations are referenced from Mean Sea Level (MSL)
Indicated by a dot with elevation in feet
Highest: bold dot with elevation in feet
MSA: Minimum safe for a radius of 25 NM from the approach NAVAID (labeled) divided into sectors of at least 90° with different altitudes
ESA: Emergency safe for a radius of 100 NM from the approach NAVAID (NOT labeled) providing 1,000' / 2,000' clearance in normal and mountainous areas respectively
Penetration Track:
Begins at the IAF to the FAF and is depicted by a bold dotted line
