Robinson R22 · R44
W&B, density altitude, METAR decode, and Robinson checklists — built for student and returning pilots.
Features
CG calculation plotted on the R22/R44 limits envelope. Pass/fail with margin to forward and aft limits. Save named configurations.
Pressure altitude + OAT → density altitude with plain-English performance impact. Flags DA thresholds relevant to Robinson hover margins.
Raw METAR and TAF in plain English. Ceiling, visibility, wind, altimeter, remarks. Go/no-go summary framed for VFR helicopter ops.
Normal and emergency procedures for R22 and R44. Tap-to-check with hold-to-confirm on critical steps. Fully offline.
Log events per tail number. Visual warning as the 5-event limit approaches. Per-tail history for A&P and CFI review.
Search by name, ICAO, or city. Nearby airports by GPS. Frequency cards: CTAF, tower, ATIS, approach. Works offline.
Key regulations and procedures from Parts 61 and 91 plus AIM chapters on airspace and weather. Fully bundled — no network required.
Pilots use this on the ramp in sunlight and in dim cockpits. Numbers are big, labels are small, contrast is high.
Checklists, W&B, and DA never touch the network. Airport data is bundled locally. Weather degrades gracefully.
Pass/Fail/Caution uses color + icon + text — never color alone. Calculated outputs always carry a disclaimer.
