An SCBA squad training calculator per Order No. 640: control pressure, work time and the whole worked solution. Fully offline, for practice and self-checks. A training calculator for practice and self-checks in gas and smoke protection service (GDZS) work. It computes SCBA squad parameters using the methodology of EMERCOM of Russia Order No. 640 of 27 June 2022 (Appendix No. 3). Data and formulas are shown as-is and require your own verification; the results are not meant for use in real emergencies. Fully offline, with no ads and no analytics. Enter each member's switch-on pressure and the switch-on time - the calculator shows the control exit pressure, the exit order time, the total work time and the expected return time. Below the result is the whole worked solution: every formula, the substituted numbers and each intermediate value, so any step can be checked by hand. The methodology is open: the formula source is cited, and the reserve factor k and air consumption Q can be checked against the order's text, adjusted if needed and marked as verified. Until you confirm the parameters yourself, the app plainly shows "Not verified by you" - it does not claim the normative data is true; it gives you the tools to check it. What you get: - Squad parameters: control exit pressure, exit order time, total work time, expected return - The worked solution, step by step: formula, substitution, result - nothing hidden behind the final number - Apparatus presets, each citing its data source: PTS Profi, PTS Profi-240, AP-2000, AIR-98MI, Dräger PSS, PTS Bazis-168, Omega (compressed air), Ural-10, KIP-8, Dräger BG-4 (compressed oxygen) - plus your own - Check and edit the k and Q coefficients, with a "verified by you" mark - A reference of the Appendix No. 3 formulas, each with an explanation - Pressure conversion: kgf/cm2, bar, MPa, psi - one value in every unit at once - A calculation journal kept on the device - Russian and English, light/dark/system appearance Private by default. The app works fully offline: no network requests, no accounts, no ads, no analytics, no tracking. The journal and settings are stored on your device only. A disclaimer is shown on first launch and available in the About section: the data and formulas require verification, and the app is not for use in emergencies or outside training self-checks. Requires iPhone with iOS 26 or newer.
