CFI Tools Takeoff Landing Distance at Mac App Store analyse

---------------------------------- CFI Tools Takeoff Landing Distance ---------------------------------- 
PURPOSE: The Takeoff Landing Distance App is used to calculate Takeoff and Landing distances for a given Aircraft under given conditions. Calculation is available for 29 Aircraft ---------------------------------------- Beechcraft Bonanza V35 Cessna 150-M Cessna 172-L Cessna 172-M POH Cessna 172-M 1974 Owners Manual Cessna 172-N 1979 Cessna 172-P Cessna 172-R Cessna 172-S Cessna 182-R Cessna T182-T Cessna 310-R Cessna Cardinal Cirrus SR20 Diamond DA 20-C1 Diamond DA 20-C1 with Gross Weight Increase Diamond DA-40 Grumman AA-5B Tiger POH Rev 4 1983 Grumman AA5B-137 1979 Owners Manual Mooney M20M Piper PA-28-161 Warrior II Piper PA-28-181 Archer II Piper PA-28-236 Dakota Piper PA-28R-201 Arrow III Piper PA-28R-201T Turbo Arrow III Piper PA-28RT-201T Turbo Arrow IV Piper PA-28RT-201T Turbo Arrow IV Flaps 25 Piper PA-32-301 Saratoga Socata TB 20 Why only these 29? Because these are the aircraft that I am currently flying. As I get requests to add others I am doing that. Also, these are some of the most popular GA airplanes. How it works ------------- 1. Select an aircraft - 29 are available 2. Select an airport - The App comes with a worldwide airport database. - Runway information is available only for US airports 3. Enter conditions - Wind, temperature, pressure altitude, weight and runways - US runway information is filled automatically or can be entered, there is also an option to define default runways on the Options tab 4. Check the results Real time METARs for weather ------------------------------ If the airport has a METAR station the current weather can be obtained by touching the "Get WX" button Internet access is required to get the weather Options Tab ------------ You can select a default Airplane and Airport to be loaded at startup. Weather can also be set to load automatically at startup. Measurement units for Wind speed, temperature, Distance and Weight can be set on the Options Tab. As Always ---------- Make sure that any Takeoff and Landing calculations are verified using the manufacturers approved flight manual or POH. Please Note ------------- I have tested these calculations and believe them to be reasonable. However I want to emphasize the need to verify them. I have had some experience building other software that uses METAR data for input. One thing that you may not realize is that METAR data may be entered by hand. That means that it is possible that there could be typos or simply some added information that is not expected by the software. This added information could cause unpredictable results and the user should be alert to this possibility. ---------------- About CFI Tools ---------------- Im a Pilot and a CFI. I build these iPhone apps and other software for my own use. Some other pilots saw them and said "Hey you should sell those". So here they are for sale. I hope you enjoy them. Any suggestions for improvement or new apps are always welcomed. Have a good flight.
