Approach coverage

KMTH’s instrument coverage is balanced across its sole runway: one RNAV (GPS) approach serves Runway 07 and another serves Runway 25. Either direction therefore has a published GPS procedure, but no other approach type is represented. With no second runway, the 5,008 ft length and 07/25 alignment define the field’s available runway options.

Regional chart context

Every nearby airport listed has a broader procedure set. KEYW has the thinnest coverage among them, while KHST has the broadest; X51 and KNQX are also substantially better represented than KMTH. The Miami Sectional and Caribbean 1 VFR chart complement the terminal procedures with wider-area visual coverage.
