Diamond Mass & Balance calculation App with easy and interactive weights adding and real time Chart plotting. You can calculate for DA20 models: DA20-A1, DA20-100, DV20-100, DA20-C1, DA20 i and DV20 E. Check out the CG moving while you're selecting your Weights. Get access to Loading Charts for accurate reading. Red Dot "marks the Spot". Also Red warning alerts if you're overweight! Create your PDF file with your loadsheet in a professional looking sheet. Write your remarks in it, save it, print it, share it or e-mail it! Includes regulatory data such as A/C registration, departure aerodrome, arrival aerodrome, time and date. Convert all necessary weight and fuel Units on a dedicated page. You can retain data from A/C's Registration, BEW and Arm, Pilot's weight and arm so that you don't have to insert it every time you restart your App, if the A/C and pilot are the same as the last flight. Enjoy your Mass and Balance on your iPad or your iPhone! Available for Diamond Aircrafts. Also available for Cessna and Piper aircrafts.

Microwave Link Calculator: plan point-to-point microwave links in minutes Built for telecom and transmission engineers, Microwave Link Calculator turns two site coordinates into everything you need on the tower: distance, azimuth, tilt, Fresnel zone, terrain profile and expected receive level. It works with links from any vendor, such as NEC Pasolink, SIAE, Ceragon, Ericsson MINI-LINK and Huawei. NEW IN THIS UPDATE • Site library: import your sites from a CSV or text file, paste a list, or add them one by one. • GPS autofill: start typing a site name in a link and pick it from the suggestions. Its coordinates are filled in for you, and you can still edit them. • Map crosshair: move the map under the crosshair and tap to place a site exactly where you want it. • Redesigned link form: Site A and Site B side by side, one "Set" button per site (pick on map, current GPS or paste coordinates), and quick + / āˆ’ buttons for antenna height and Tx power. • Smart checks: warnings when antenna efficiency is outside 0.5–0.8 or both sites have the same name. • Elevation profiles for links of any length, including links over 100 km. • Available in 13 languages. LINK CALCULATIONS • Distance, azimuth and tilt (up/down) between the two sites. • Fresnel zone and terrain elevation along the whole path. • Antenna gain and expected received power in free-space conditions, based on frequency, Tx power, antenna diameter and efficiency. • Antenna height above sea level for each site. • Metric or imperial units (m / ft, and m / ft / in for antenna diameter). MAP AND FIELD TOOLS • See your link on Apple Maps with standard, satellite or satellite-with-roads styles, and line it up with nearby landmarks. • Add obstacles such as new buildings or trees and see them on the elevation profile. • Built-in compass with haptic feedback for precise azimuth alignment when you're on site. • Pick a site by tapping the map, using the crosshair, or searching for a place. YOUR DATA, EVERYWHERE Links and saved sites are stored on your device and synced through iCloud, so they're ready on all your iPhones and iPads. Some features, such as the elevation profile, obstacles and the compass, require a Pro subscription.
