NavUP
Read full descriptionHide full description
NavUP keeps your aircraft's aeronautical databases current, with a workflow built for how pilots actually fly: download at home on wi-fi, then write to your panel's cards in the field - even with no internet. TWO SIMPLE PHASES 1. DOWNLOAD - connected to your subscription, NavUP downloads the available cycle (navigation, electronic charts, terrain, obstacles, SafeTaxi and more) and stores it on your iPhone. 2. WRITE TO CARDS - with a USB-C reader and your panel's SD cards, NavUP writes each database to the right card. Works 100% offline, in the hangar or on the ramp. BUILT FOR THE FIELD - Works with no internet when it's time to write - no more being stranded away from wi-fi. - Recognizes each card's role (MFD, PFD, spare) and writes the correct content. - Skips anything already on the card at the correct version. - Integrity check on every downloaded file. - Clean, direct interface in cockpit language. MAINTENANCE - Finds the reports recorded by the onboard computer (CMC/ENG) on the card and lets you send them to the manufacturer straight from your iPhone - by email, AirDrop or Files. - You choose which files to export. Nothing is deleted from the card. - No computer, no cable, no waiting until you're back at the hangar. ORGANIZED - Electronic charts appear as a single package covering all regions. - See the available cycle and what's left to download or write at a glance. REQUIREMENTS - An active subscription to your aircraft's database services. - An iPhone-compatible SD card reader (USB-C) and your panel's cards. NavUP is an independent tool for a pilot/operator's personal use in updating their own aircraft. It is not affiliated with or endorsed by Garmin or Jeppesen; trademarks belong to their respective owners.
