WBCheck: Weight & Balance
Your envelope in 10 seconds
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Weight & balance in 10 seconds — built by pilots, for the real preflight.
Pick your aircraft, drag the sliders, and watch your center-of-gravity envelope update live. WBCheck shows takeoff, landing and zero-fuel points against the published envelope, computes fuel burn and endurance, and — for helicopters — estimates IGE/OGE hover ceilings at your density altitude.
WHY PILOTS USE IT
• No account, no friction — open it and go.
• Works offline once loaded — perfect on the ramp with no signal.
• Live envelope with TO / LD / ZF points and the MTOW line.
• Fuel burn, endurance and reserve at a glance.
• Density altitude and hover performance for helicopters.
• One-tap PDF load sheet with a timestamped reference — sign and file.
• kg·L or lb·gal — your choice.
POH-VERIFIED PROFILES
Every aircraft profile is built from the POH and type certificate, with sources cited during development. Includes Robinson R22 / R44 / R66, Guimbal Cabri G2, Bell 206, Cessna 150 / 152 / 172 / 182 / U206, Piper Archer / Warrior / Super Cub, Beechcraft Bonanza and Cirrus SR22 — with more added on request.
FREE + PRO
Your first aircraft is free, forever. Unlock any other aircraft as a one-time purchase, or go WBCheck Pro for the whole fleet, custom profiles from your own weighing record, and every future model.
ADVISORY TOOL
WBCheck uses model reference values and starts from your inputs. Always verify and adjust against the POH and the weighing record of your specific aircraft. It does not replace the official weight and balance computation or the planning required by your aviation authority. The pilot in command is the final authority.
