What do the aircraft-fit stars mean? Scored for: twin turboprop (King Air class)
- ★★★ Strong fit for the selected aircraft
- ★★★ Good match, but with extra hurdles such as local registration, a partner or a specific sensor
- ★★★ Weak fit: wrong platform, a specialist sensor, a small area or a long ferry
- – No flying (data only)
Rules: the tender's platform (fixed-wing, helicopter, drone), required altitude, payload and equipment (fire tank, bucket, scooper, spray), endurance, low-level or over-water work, area size, specialist sensors, and local registration or ferry distance. Fire tenders: helicopters suit bucket/helitack jobs, SEATs suit tenders for single-engine or fixed-wing tankers (and spraying, vector control, bait drops), large tankers suit amphibious, scooper or large/very large air-tanker tenders; a stated tank size or type is applied. Fixed-wing survey aircraft only fit fire spotting or air-attack coordination. A first view, not bid advice.
