Courtesy Car

The courtesy car availability at GNB is due to an economic development grant from the Friends of the Granby Airport, Inc., and a cooperative effort by members of EAA Chapter 1267. The Pilot Community thanks the Town of Granby for the donation of the courtesy car for use by visiting pilots.

The GNB courtesy car is stationed at the Flight Planning Facility. The keypad access code for entry is CTAF. Further instructions on completing the required courtesy car access form and for obtaining access to the keys to the courtesy car are posted inside the Facility. It is provided on a first-come, first served basis. Pilots are requested to replace whatever gasoline is used in the car.

Noise Sensitive Notice

Due to rising terrain to the East and the highly noise-sensitive area, bearing 075 degrees from, and located only 0.5 nm East of the airport, good mountain pilots rarely, if ever, take off to the East. Study the traffic pattern chart and the noise-sensitive notice shown below.
