"QuickSearch PDF Reader is the tool you didn't realize you needed ... searches are extra fast but it's the interface design that shines ... a terrific app" -- The Unofficial Apple Weblog (tuaw.com) QuickSearch PDF Reader makes it fast and easy to find text in PDF documents. When you add a document, it is scanned in the background, so when you search, results are instant. And as well as searching within a document, you can search across all your documents at once. It’s also a great PDF viewer with a very natural style of navigation. It snaps to page boundaries, yet it’s easy to flick past them. Zooming is straightforward by pinching, or you can double-tap a region of text to zoom to fit. You can easily jump to any part of the document using the scrub bar. And everything is lightning-fast, even on large documents. You can easily get your documents into QuickSearch from other apps on your iPad or iPhone that support the "Open In..." function, such as Mail, Safari, or Dropbox. You can also use iTunes File Sharing to transfer documents to and from your Mac or PC. Full step-by-step instructions are included.

Cold Temperature Corrections – Professional Aviation Tool When outside air temperature is colder than ISA, an aircraft’s true altitude is lower than the indicated altitude—reducing terrain and obstacle clearance. To mitigate this risk, regulations require pilots to apply cold temperature corrections. The Cold Temp App streamlines this process with fast, accurate calculations based on the ICAO Cold Temperature Correction Table or precise engineering equations, ensuring compliance with ICAO PANS-OPS and FAA TERPS. In its latest revision, the app has been enhanced with additional modules: • ATMOS Module – Advanced atmospheric calculations, ISA parameters, and air data conversions. • CDFA Module – Constant Descent Final Approach planning with integrated cold temperature corrections. With expanded capabilities, regulatory compliance, and operational accuracy, the Cold Temp App is an essential professional tool for safe and efficient flight operations in cold-weather environments.
