ZKReg is an instant mobile reference of all New Zealand ZK registered aircraft. ZKReg accesses a hierarchical database; this is a much richer product than a simple spreadsheet-like flat file. Having found a particular item, you can navigate up, down and across the database with a few taps to discover all related information. All data is held on as server, which is synchronized with the publication of new data as it is published by the CAA, so its always up to date. [Please note that this app requires wifi or cellular access to the internet]. With ZKReg you can get instant answers to the following questions: • What are the registration details for aircraft ZK-abc? • Who is the registered owner? • Show me ALL of the aircraft that they own or operate • Give me a list of ALL other aircraft which are of the same type, or are from the same manufacturer. • Find any owner or operator (and therefore all of their aircraft) from an auto-complete style drop down of names. • For any of the above, make a single-tap call to the internet search engines, to discover anything known about the aircraft, owner, operator, or model etc. ZKReg implements a tight integration with the internet’s leading search engine. If you want extended information about an owner, or need to know engine details, or get pics of the aircraft, it’s generally only a few taps away. ZKReg comes with two screen presentations (selected in iPhone…Settings) - a daylight format, and a night format, so you won't impair your night vision from the cockpit late at night! The app is fully documented through on-screen help, with full email support to all purchasers from the developers.
