Which of the following is NOT an approved flight planning service provider for Whitewind?

• A. Airinc
• B. Jeppesen
• C. Garmin
• D. Fltplan.com

Answer: (C)

In Part 135 operations, a carrier relies on approved flight planning service providers to deliver standardized planning data, weather, NOTAMs, weight and balance, fuel calculations, and an official filed flight plan. These providers are vetted to meet the operator’s regulatory and data integrity requirements.

Garmin is primarily an avionics manufacturer that offers onboard navigation and pilot tools, including flight planning apps for individual use. While useful for general planning, it isn’t the type of operator-approved flight planning service that Whitewind uses to prepare and file official company flight plans and to provide fleet-wide planning data. The other providers—Airinc, Jeppesen, and Fltplan.com—are established sources for dispatch-level planning, weather, route analysis, and filing, which is why they appear on Whitewind’s approved list.

So, Garmin isn’t an approved flight planning service provider for Whitewind.
