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) .

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 mode which has emergency glide capability and allows you to build custom plane types. We continue to add features to this version. Supported iPhone models: : X and up Operating system: iOS 14.3 or better 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.
