What KGNB publishes
Instrument approaches at KGNB
Granby-Grand County has 1 published instrument approach of 1 type (RNAV (GPS)). 1 of them offers vertical guidance; RNAV (GPS) gives the lowest minimums. One is circling only — bringing you to the airport rather than a runway, to circle for whichever runway the wind favors at circling minimums.
No published approach to runway 09 and 27: landing on those ends in instrument conditions means a circling approach or a visual after breaking out.
Takeoff, alternate and surface information
- Takeoff minimums are published for KGNB. Standard is 1 statute mile visibility for one and two engine aircraft (½ mile for more than two) unless this section says otherwise; Part 91 operators are not bound by them but the obstacle notes apply to everyone.
- Granby-Grand County has an obstacle departure procedure (ODP): the charted way to clear terrain and obstacles after takeoff in instrument conditions. ATC does not assign it; under Part 91 it is recommended rather than required, and it is what you fly when no SID or radar vectors have been given.
- Non standard alternate minimums are published: if you file KGNB as an IFR alternate, the required forecast is higher than the default 600-2 for precision or 800-2 for non precision approaches. Check the alternate rule tool.
