Takeoff roll vs available runway
Indonesia is hot and often high — density altitude lengthens the takeoff roll, while headwind shortens it and tailwind lengthens it. Everything below updates live.
⚠ Planning tool only — not a substitute for the POH. Weight & balance limits use the Van's RV-7/7A Section 14 sample data; your actual aircraft empty weight, arms and limits WILL differ — enter them under "Advanced". Performance figures derive from Van's published specs (180 HP, constant-speed prop), a standard density-altitude model and a textbook wind/ground-roll correction; treat best glide as a typical benchmark and the crosswind/headwind as planning components only. Always confirm against your POH, current AIP and NOTAM. The pilot in command is solely responsible for the final determination.
