About

HD Flight Log

Features
Read full description

HD Flight Log is a simple personal flight logging and operational note-taking app designed for pilots who want a fast way to record flight activity in the field. Start a flight in seconds, complete the entry after landing, and track key details such as flight time, landings, cycle counts, hook hours, fuel values, notes, and attached photos. Entries are grouped by day, with daily and rolling totals to help you quickly review recent activity. Customize your setup by aircraft type so each aircraft can show the fields that matter most. Configure aircraft registrations, adjust visible fields, manage fuel units, and back up or restore your setup when needed. Version 1.0.2 adds new operational tracking tools, including an Air Time Calculator for tracking takeoff-to-landing segments, a Loads/Drops counter for bucket drops, sling loads, or similar repetitive operations, and improved timezone-consistent time calculations for flights that may cross time zones. Deleted entries can also now be moved to a recoverable Deleted Entries section before being permanently removed. Features include: • Fast start-flight workflow • Editable flight entries • Daily totals by aircraft • Rolling flight-time summaries • Configurable aircraft types and fields • Aircraft registration management • Fuel, cycle, landing, hook-hour, and note fields • Air Time Calculator with segment logging • Loads/Drops counter • Timezone-consistent flight time calculations • Photo attachments for flight entries • Deleted Entries recovery section • iCloud sync across devices signed into the same Apple ID • Backup and restore support • Configuration import and export HD Flight Log is intended as a personal flight logging and operational note-taking tool.
