Professional Fuel Management for Every Cockpit.
The Seahive Aviation Fuel Conversion Card Set is built for the line: printed on high-quality, rugged, waterproof plastic that won't fade or tear. At standard credit card size, these cards are designed to live behind your pilot ID on a lanyard, tucked in your wallet, or clipped to your kneeboard—ensuring critical data is always within reach for quick and easy refueling.
Fuel is weight, and weight is safety. The Seahive set replaces mental math, handwritten "cheat sheets," and clunky EFB apps with a professional, standardized reference tool. Whether you are a student pilot in a Cessna 172 or a professional pilot flying a turboprop or a jet, these cards provide instant data for accurate fuel management.
Seahive provides two distinct, specialized cards:
Avgas 100LL Card: Calibrated to ISA 6.0 lbs/gal (0.72 kg/L).
Jet-A Card: Calibrated to ISA 6.7 lbs/gal (0.80 kg/L).
Dual-Sided Efficiency for the Modern Cockpit Don't fumble with an E6B or a smartphone app while standing on a busy ramp in the rain or sun.
Front: A lightning-fast reference table to ensure accurate refueling at a glance.
Back: A conversion flowchart—the "logic map" that lets you calculate any custom fuel load in seconds.
The Perfect Gift for the Aviator in Your Life Whether it's a graduation gift for a new student pilot, a "thank you" for a CFI, or a professional tool for pilots on the line in any aircraft, the Seahive Aviation Fuel Conversion Card is the practical accessory every flight bag needs.
Master your math. Protect your flight. Choose Seahive.
