## Description

Only for educational purposes.
Instant Q400 takeoff, landing, cruise and missed-approach performance — V-speeds and weight limits in seconds.

Fast, accurate takeoff and landing performance for the DHC-8-402 (Q400) — built by pilots, for pilots.

Q400 Performance Calculator turns AFM tables into instant results on the flight deck. Enter your conditions and get V-speeds, weight limits, and runway-specific numbers in seconds — no paper charts, no guesswork.

KEY FEATURES
• Takeoff — V1/VR/V2, max weights and limit codes for dry, wet, tailwind, MEL and contaminated runway conditions
• Reduced (assumed-temperature) takeoff with torque selection
• Landing — Vref, Vtarget, Vmax, go-around speeds with wind and contamination corrections
• Cruise — LRC, ISC, HSC, MCR plus single-engine and holding performance
• Missed approach climb gradients
• De-icing / icing speed corrections applied automatically
• Built-in airport and runway database — elevation, length, slope, shift

Designed around a clean cockpit-style interface: high-contrast values, dark display, and a layout that reads at a glance under any lighting.

This app is a planning aid. Always cross-check results against the approved Aircraft Flight Manual and your operator's procedures. The pilot in command remains responsible for all performance decisions.
