Features & Capabilities

v4.4: live altitude sync between paired iPads and iPhones. Consolidated OPS tables. Polished navigation, refined abbreviations, sharper readouts.

sQRH is an electronic Quick Reference Handbook designed for airline pilots. It provides instant access to emergency procedures, checklists, operational data, deicing holdover times, and flight time limitation calculations -- all in one app, directly on your iPad or iPhone.

QUICK REFERENCE AT YOUR FINGERTIPS

Browse your airline's QRH data with a pilot-optimized interface. sQRH connects to your airline's server to download and keep your aircraft data up to date, including per-MSN applicability. You can also import eQRH ZIP loads directly from Files -- no server required.

FLIGHT TIME LIMITATIONS AND REST (FTL) On-the-spot FDP limitation calculator based on EASA ORO.FTL. FC and CC crew types with augmented crew (3 FC / 4 FC). Duration timeline with sector blocks, elapsed/remaining time, and color-coded limit zones. Crew rest split with live cruise timer, configurable rest buffers, and local notifications. Share full FTL state to a paired device. Covers split duty, delayed reporting, commander extension/discretion, minimum rest, and cumulative limits.

COCKPIT CHECKLIST SYNC

Pair two iPads by scanning a QR code -- once paired, they auto-reconnect every session. Checked items, section expansions, and resets sync live via encrypted MultipeerConnectivity (no internet required). Both devices must use the same aircraft and QRH version; if they differ, sync pauses with a warning.

TAKEOFF CG/TRIM CALCULATOR

The Takeoff CG/TRIM POS checklist section features an interactive calculator. Enter your CG% using a cockpit-friendly numpad and get instant THS trim position with a horizontal gauge. Trim data is read directly from eQRH XML files for maximum accuracy across all aircraft variants.

VERSIONS (VER)

Track all your EFB app and system versions in one place. Pull down to check the App Store for updates -- a badge appears next to outdated entries. Create, edit, and archive version records. Works standalone with local data, or syncs with a server automatically on launch.

EMERGENCY PROCEDURES (EMR) Instant access to emergency evacuation and landing procedures. Toggle between EVAC and EMER LANDING with a single tap. Full procedure rendering with inline illustrations, warnings, cautions, notes, tables, and ECAM references.

OPERATIONAL ENGINEERING BULLETINS (OEB) Browse and view OEB procedures with complete rendering of all procedure elements including tables, graphics, nested lists, and action blocks.

CHECKLISTS (CKL) Aircraft checklists with full content rendering, proper formatting, and state tracking. Syncs live with paired devices.

STANDARD OPERATING PROCEDURES (SOP) SOP reference materials with expandable sections and complete procedure content display.

ABNORMAL PROCEDURES (ABN) AND OPERATIONAL DATA (OPS) Two-panel split navigation: category sidebar on the left, procedures on the right (iPad). On iPhone, tap to drill into each category. Each procedure is individually collapsible. Custom airline tabs are auto-detected from loaded data.

ALTITUDE REFERENCE (ALT) Interactive altitude table with ISA deviation and QNH correction. ICAO and metric (Chinese RVSM) flight levels. Configurable max altitude with RVSM markers. Big single-line readout with tap-to-toggle m/ft, 3-state GPS icon, and long-press to reset ΔISA/QNH. ALT state syncs live to paired devices over MultipeerConnectivity.

HOLD-OVER TIME (HOT) -- IN-APP PURCHASE Deicing holdover time calculator with FAA and Transport Canada 2026 data. Select weather and fluid type (I-IV) for accurate holdover times. Countdown timer with Live Activity on lock screen and Dynamic Island.
