Sleeping Altitude Ascent Planner
Audit a sleeping-altitude itinerary rather than only the highest summit reached during a day.
Your altitude itinerary inputs
An itinerary audit using selected published planning checks, not an AMS probability or a declaration that an ascent is safe.

How to use Sleeping Altitude Ascent Planner
- Audit a sleeping-altitude itinerary rather than only the highest summit reached during a day.
- The report identifies selected numerical planning checks from altitude guidance.
- The chart shows sleeping elevation and the table shows signed night-to-night changes.
Worked example
A repeated 3500 m night has zero sleeping gain. It remains in the timeline rather than being removed from the itinerary.
Formula, accuracy & limitations
Daily sleeping gain = current night altitude − previous sleeping altitude. Report maximum positive daily gain, total positive climb and repeated-altitude nights. Flag gains over 500 m when the new night is above 3000 m, and an initial single-day arrival at 2750 m or more from below.
An itinerary audit using selected published planning checks, not an AMS probability or a declaration that an ascent is safe. Prior acclimatisation, travel route, symptoms and health are not assessed. No preventive medication is recommended.
The primary result is rounded to two decimal places. Calculation tables show up to four and supporting metrics up to six. Very small nonzero values use scientific notation. Display rounding is not fed back into the arithmetic.
Official source and method context ↗Record where each night is spent
Audit a sleeping-altitude itinerary rather than only the highest summit reached during a day. Enter your previous sleeping altitude and each planned night in order. A repeated elevation is meaningful and stays in the list as a night without further sleeping-altitude gain.
Separate individual checks from a risk diagnosis
The report identifies selected numerical planning checks from altitude guidance. It does not combine them into a validated personal risk score. A route without a displayed flag is not certified safe, and the calculator cannot account for how recently a person was acclimatised or whether symptoms have already appeared.
Inspect gains and rest nights
The chart shows sleeping elevation and the table shows signed night-to-night changes. Descents remain negative changes; total positive climb is reported separately from net elevation gain. Repeated nights are counted descriptively and are not automatically judged adequate acclimatisation for every traveller.
Use professional advice when the context changes
Underlying conditions, illness and altitude symptoms require context beyond a spreadsheet. This tool does not suggest acetazolamide, oxygen, a rate of ascent for an individual or a decision to continue climbing. It is a transparent itinerary worksheet to discuss alongside authoritative travel guidance.
Frequently asked questions
Does no flag mean my trip is safe?
The numerical checks cover only part of itinerary planning and do not certify personal safety.
Should I enter daytime summit altitude?
Use the altitude where you sleep for each night. A summit reached and left the same day is a different exposure detail.
Do repeated nights disappear from the calculation?
They remain as zero-gain nights and are counted in the itinerary.
Does the tool prescribe altitude medication?
No medicine, oxygen plan or individual treatment recommendation is generated.
