Build a signal fire that gets seen
The point of a signal fire is smoke and contrast, not warmth.
1. Pick a spot with a wide sky view — a ridge, clearing, or lakeshore. Not under trees.
2. Build three fires in a triangle 25 m apart if you have the fuel; three of anything is a distress signal.
3. Keep a pile of green boughs, wet moss, or damp grass at each fire, ready to dump on.
4. Against snow use dark smoke: green vegetation. Against dark forest use white smoke: damp grass, moss.
5. Only light when you actually hear or see a search — smoke ignored is smoke wasted.

Aim a signal mirror at an aircraft
A signal mirror is visible 20+ miles on a clear day — but only if you aim it.
1. Hold the mirror close to your face and sight through the aiming hole (or over the top edge).
2. Extend the other hand as a V with two fingers framing the aircraft.
3. Tilt the mirror until the bright spot from the sunbeam lands on your fingers.
4. Sweep across the aircraft repeatedly — a moving flash catches attention.
5. Even without a proper mirror, use a phone screen, CD, or polished can lid the same way.

Ground-to-air signals every pilot knows
Five internationally recognized symbols. Make each one 10 ft / 3 m tall in high-contrast material.
1. V = require assistance.
2. X = require medical assistance.
3. N = no or negative.
4. Y = yes or affirmative.
5. → (arrow) = proceeding in this direction.
6. Stomp them into snow, dig them into sand, or lay them out in dark logs on light ground.
Tip: Size and contrast matter more than shape. From 2,000 ft, small is invisible.

Signal for rescue with the rule of three
Three of anything — fires, whistle blasts, gunshots, flashes — is the international distress signal recognized by rescuers.
1. Build three signal fires in a triangle or straight line with 30–50 feet between them, in the largest clearing you can find.
2. Prep them fully but light only when you hear or see aircraft or searchers — the goal is instant ignition, not constant burn.
3. Have wet leaves, green boughs, or damp moss ready to throw on for thick smoke by day.
4. By night, add dry fuel for tall, bright flames.
5. If you have a whistle, use three sharp blasts, pause, repeat. Three flashes with a mirror or headlamp follow the same pattern.
Tip: Rescuers look for straight lines and geometric shapes because they don't occur in nature. A single fire may be dismissed; three in pattern is unmistakable.

Signal SOS with light, sound, or ground marks
SOS is the most universally recognized distress signal — three short, three long, three short — with any signaling method.
1. Light or sound: three short bursts, three long bursts, three short bursts, pause, repeat.
2. With a whistle: three quick chirps, three 2-second blasts, three quick chirps.
3. With a flashlight or mirror: three short flashes, three long flashes, three short flashes toward the observer.
4. On the ground: stamp or scrape 'SOS' in letters at least 10 feet tall in snow, sand, or a clearing.
5. Keep repeating in cycles with a pause between; a single SOS is easy to miss.
Tip: The pattern matters more than the medium. A rescuer who hears three-three-three anything will investigate.

Choose high-contrast colors for signal panels
Contrast beats color. What matters is that your signal looks nothing like the ground around it.
1. In snow or on light rock: use dark materials — a garbage bag, dark jacket, or scorched wood.
2. In green forest or grass: use bright orange, yellow, or blaze pink if you have them; a silver space blanket also works.
3. On dark ground or wet dirt: light or reflective materials — foil, mirrors, or white cloth.
4. Weight the corners and edges with rocks so the panel doesn't blow away.
5. Combine ground panels with a geometric shape — a big X or triangle — so aircraft recognize it as human-made.
Tip: Bright red is the color humans notice fastest in natural settings. If you have a red jacket, keep it on top when signaling.

Signal with a whistle
A whistle carries farther than a voice and works when you're exhausted. Three blasts is the universal distress call.
1. Three short blasts = distress or need help.
2. Three of anything — whistle, flashes, shouts — is recognized as a call for assistance.
3. Pause after each set of three to listen for a response.
4. Two blasts can mean 'all clear' or 'come here' within a group, but agree on meanings beforehand.
5. Blow in bursts; a continuous blast wastes breath and is harder to locate.
Tip: Carry a whistle on your pack strap or neck lanyard, not buried in a pocket. Seconds matter in moving water or dense brush.

Build a night signal fire
At night, flame and light contrast matter more than smoke. A signal fire needs to be seen from the air.
1. Choose a high, open spot with a clear view of the sky — ridge, clearing, or shoreline.
2. Build three small fires in a triangle 25 meters apart if you have the fuel and it's safe.
3. Keep a large supply of dry, fast-burning material ready to throw on when you hear an aircraft.
4. Use bright flames against dark terrain; against snow, dark smoke from green boughs contrasts better.
5. Only light when you have reason to believe searchers are nearby — a fire left burning is a fire that can escape.
Warning: Never build signal fires in dry, windy conditions where embers can ignite surrounding forest. Clear the ground to mineral soil first.
