Virtual PAPI vs Fly2Gether

Pilots love runways with visual descent guidance, such as PAPI or VASI, but unfortunately they don't exist everywhere. This app provides an adjustable visual descent guidance for every runway on the planet. The pilot can select an airport, a runway, adjust the desired descent angle and the aiming point, then Virtual PAPI will create a glide slope indicator style. The glide slope will provide accurate vertical guidance to the aiming point from any direction, 360 degrees, providing a valuable guidance for any type of approach, like base entries, short approaches, straight-ins, etc. The app comes with over 30 thousand runways in its offline database, and more will be added as they are discovered. The app works completely offline and never tries to use the internet. All it needs is access to your location. Virtual PAPI is and free and open source, with all the code available on GitHub.

Fly2Gether turns your iPhone into a wireless flight controller for PC flight simulators. Designed specifically for aviation, Fly2Gether provides the controls pilots use most often during flight while avoiding many of the limitations of traditional gamepads and generic mobile controllers. ESSENTIAL FLIGHT CONTROLS Fly2Gether focuses on the controls that matter most while flying: • Pitch and roll control using device motion • Rudder (yaw) control • Throttle control • Elevator trim • Brakes • Flaps By focusing on the controls used continuously throughout a flight, Fly2Gether provides a clean and efficient interface that works naturally on the iPhone's compact screen. Less frequently used simulator functions remain available through your keyboard, mouse, or the simulator's virtual cockpit. DESIGNED FOR PRECISE AIRCRAFT CONTROL Unlike traditional gamepads, Fly2Gether separates flight controls so that each finger is responsible for only one axis at a time. This helps eliminate unwanted mixed-axis inputs that can make precise flying difficult. Fly2Gether also features a unique pitch-freeze system. The pitch axis can be frozen and released instantly, allowing you to change your seating position or device angle without disturbing the aircraft. This is especially useful during long flights and while flying from a couch or other relaxed seating position. NO EXPENSIVE HARDWARE REQUIRED Enjoy realistic flight control without investing in bulky simulator equipment. Fly2Gether provides the essential controls needed for normal flight operations using the device already in your pocket. Ideal for: • Flight simulator enthusiasts • Travel and portable simulator setups • Users without dedicated flight hardware • Pilots looking for an additional control option DUAL-JOYSTICK SHARED CONTROL Fly2Gether also supports collaborative flight simulation. Two pilots can share control of the same aircraft using a built-in control ownership system. To prevent conflicting inputs, only one pilot controls the aircraft at a time. When the second pilot wants to take over, they simply press the "I Have Control" button and control transfers instantly. Ideal for: • Flight instruction • Simulator training • Shared cockpit flying • Cooperative simulator sessions COMPATIBLE WITH WINDOWS, LINUX AND MACOS On Windows and Linux, Fly2Gether communicates directly with the companion application running on your computer. On macOS, Fly2Gether supports a low-cost Wi-Fi microcontroller board that receives control data from your iPhone and presents itself to the Mac as a standard USB flight controller. Compatible boards are widely available and typically cost around US$20. Whether flying solo or together, Fly2Gether makes realistic flight simulation more accessible and affordable.
