NRST vs TLAR

Don't miss your airport! Designed for pilots of any size aircraft, this app provides you with bearing and vertical speed required to nearby airports. The following information is shown for destinations: • Distance from current location • Field Elevation • Descent rate required • Time to Top of Descent (TOD) • Bearing • Frequencies • Runways • Glide distance delta Additionally your current speed, course, altitude and vertical speed are displayed. Tapping on the information button, Time to TOD or Target Altitude allows you to customize the desired descent rate. All data is updated in real time as you fly. You may choose a nearby airport or select an airport by identifier by scrolling down on the airport list. Filter by runway length and surface type and choose any of the following: airports, seaplane bases, heliports, balloon ports and closed airports. You may optionally provide a glide ratio for your aircraft. The glide distance long or short of the selected airport is then displayed and is conveniently color coded. A positive, green glide delta indicates the glide distance has been estimated to exceed the distance to the airport with a 25% safety margin. Runway headings, if known, are used to draw runways on the heading indicator. If the magenta arrow is pointed straight up and aligned with a runway then you are headed straight in. Worldwide airport information is provided by multiple sources. Canada, Europe and all continents are covered! For more information go to ourairports.com/world.html. Database updates are performed daily. Your location and altitude is provided by your device's location services. If location or altitude is not available that information will not be displayed however you can still search for an airport by identifier. Unfortunately external GPS devices are generally NOT compatible. You must be moving for course information and the magenta relative bearing arrow to be displayed. The Watch app has many of the same features and fits on your wrist. See distances to nearby airports or bearing to a selected airport. Frequencies and runway lengths can be seen with a swipe. A green glide icon or delta indicates glideability is likely. Just like the iPhone and iPad app, the Watch app requires GPS information to locate nearby airports and relative bearing. Additionally, altitude is needed to calculate descent rates. Feedback and feature requests are appreciated. Thanks!

The TLAR ("That Looks About Right!") app is designed to improve general aviation pilot situational awareness of aircraft performance. TLAR computes takeoff, climb, cruise, and landing performance of the following single-engine piston-powered aircraft types (Expert version allows you to build your own plane type, below are pre-loaded): • Aero L39C (L39) • American Champion Super Decathlon (8KCAB) • Bonanza A36 (A36) • Cessna 150M (C150M) • Cessna 152 (C152) • Cessna 170B (C170B) • Cessna 172M (C172M) • Cessna 172N (C172N) • Cessna 172S (C172S) • Cessna 180K (C180K) • Cessna 182P (C182P) • Cessna T-240 (C240T) • Cessna A185F (CA185F) • Cirrus SR20 (SR20) • Cirrus SR22 (SR22) • Cirrus SR22T (SR22T) • Cub Crafters FX-2 (FX2) • Cub Crafters FX-3 (FX3) • Diamond DA40 (DA40) • Glasair Sportsman (GLSP) • Glasair Glastar (GLST) • Harmon Rocket II (HROC2) • Kitfox 7 Series SS (K7SS) • Kitfox 7 Series STI (K7STI) • Mooney M20F (M20F) • North American Aviation T-6G (T6G) • Piper J3 (J3) • Piper PA18 (PA18) • Piper PA22 (PA22) • Piper PA24-250 (PA24250) • Piper PA24-260 (PA24260) • Piper PA28-140 (PA28140) • Piper PA28-181 (PA28181) • Vans RV-4 (RV4) • Vans RV-6 (RV6) • Vans RV-7 (RV7) • Vans RV-8 (RV8) • Vans RV-10 (RV10) • Vans RV-12iS (RV12iS) • Vans RV-14A (RV14A) The basic version of the app is free.  It predicts aircraft performance using user-entered weather and elevation information in a static fashion like a calculator. The pro version requires a subscription, but offers significantly more features and capabilities. It dynamically recalculates performance in real time responding to the aircraft's 3D position and automatically updated weather conditions. With the addition of airfield information from either the included 73,000 airfield global database or user-defined airstrips, TLAR computes additional performance metrics such as predicted height by end of the runway on takeoff, bearing, distance, glide path, and descent rate required to the airfield, predicted stopping point on the runway during landing, approach stability on short-final, displaying that status visually, and audibly in your headset (for aircraft with communication panels that can connect via bluetooth or cable to your phone). The pro version allows the pilot to set tailorable safety margins and warns the pilot if predicted performance will violate any of the set safety criteria. The expert version adds patent-pending emergency glide functionality, telemetry recording, and automatic landing zone loading. It will tell you where and how high you will be when your aircraft will be capable of conducting an engine windmilling turnback to the runway on takeoff or in cruise. During takeoff and climb it will show you your current wind-corrected glide footprint and announce on headset your latest abort point, when a turnback is possible and show you the route of flight back to the runway along with your predicted altitude when reaching the runway. The expert version also has a heads-up display, NEXRAD radar, custom plane types, and store telemetry. We continue to add features to this version. Supported iPhone models: : X and up Operating system: iOS 17 or better for new interface (14.3 thru 16 will download the legacy TLAR version which has nearly the same functions, but a different interface). Supported iPad models: cellular models required (GPS) with minimum A12 chip performance or greater For more information or to download the TLAR Pilot Manual see www.TLARPILOT.com.
