The Problem

From raw OFP PDF to structured cockpit data.

Every flight starts with a 150-page PDF - raw, unstructured, and difficult to navigate mid-flight. AvComp parses your Lido OFP in seconds and turns it into a structured, interactive briefing that stays with you from gate to gate.

The Tools

Everything you need in flight. Nothing you don't.

Built by pilots. Designed for real operations.

OFP Brief

Parse and brief.

Parses your Lido OFP PDF in seconds - Lido Classic and Lido NextGen formats. Hero card, fuel plan, waypoints, alternates, NOTAMs, and ETOPS data, all structured and searchable.

ATC

Record clearance.

Two tools in one tab: a purpose-built clearance recorder with a field-adaptive keyboard, and a tap-to-build taxi route tool with color-coded operational chips.

Weather

Route weather.

Live METAR + TAF for any ICAO airport. One tap loads your full OFP route with departure, destination, alternate, and enroute stations grouped for fast scanning.

Calculators

OFP-bridged math.

Six calculators: Alternate fuel, FDP, Wind, Distance/Altitude, Volume, and Timezone - designed around operational aviation inputs.

Logbook

Export-ready records.

Digital logbook with PDF import and export in regulatory formats, including night time support from civil twilight at each airport.

Diversion

Contingency flow.

In-flight contingency procedures for 35 FIR regions, covering weather deviation, engine failure, decompression, medical, comms loss, and fire or smoke.
