About this puzzle

A hard 50x50 grid in the transport theme, Helicopter 50x50 Nonogram hides a recognisable picture once the logic clicks. About 31% of the grid is shaded — 772 filled cells out of 2500 — which makes for a fairly balanced board.

The biggest single run here is 38 cells long — fill that first and the surrounding lines fall into place faster. Budget about 38 minutes for a relaxed solve.

How to solve this nonogram

On a large board, divide it into zones: lock in the longest clues, mark proven-empty cells with X, and only then chase the tight lines. With balanced coverage, alternate between filling forced cells and ruling out empties to keep both kinds of clue moving. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
