The program Aviation RF Link allows quick calculation of the forward link from a ground station to an aircraft. Based on the RF power of the ground station, the tool calculates the distance with a given field strength to be achieved at the aircraft antenna or calculates the field strength at a given power and distance to the aircraft.
The tool calculates the path loss based on line-of-sight (LOS) conditions and does not take into account multipath propagation on the ground.
In addition to the RF path, the tool calculates the radio horizon based on the given height of the aircraft and the ground station. If the calculated LOS is lower than the distance that can be achieved with the given radio conditions, this is indicated by a red dot on the LOS tab. In this case, the radio horizon is the limiting factor and not the RF link budget.
The line of sight is calculated in accordance with ICAO Annex 10 Vol. V.
The default for the antenna gain of 2.14 dBi corresponds to an omni directional antenna.
The default for the field strength of 75 uV/m corresponds to the ICAO recommendation for minimum reception at the aircraft antenna.
To start calculation, just select a row by touching it and change a specific value.
After touching the "Return" button, the dependent values are calculated automatically.
If any value other than distance is changed, the distance is recalculated. If distance is changed, the field strength is recalculated.
If you change a unit, the corresponding numerical values are converted. For example: 1 mW yields 0 dBm if the unit is changed from mW to dBm. Also conversion between feet and meters, and between nautical miles and kilometers is performed.
Developed by a pilot and inspired by the aviation tradition of cockpit checklist handling, this application allows you to easily run through checklists and even will read you items. Checklist data is stored in a plain text file on your phone, and is easily edited on your computer.
It comes with a pre-loaded check list which has routines, such as "Daily Routine", "Weekly Routine", "Monthly Routine" and etc. You may edit them or add new routine/chores.
You will need to install this app on your phone(not SD card) in order to add widget to home screen.
Since version 2.0, users are allowed to create multiple lists. In full version, user can use widget view as a dashboard to combine multiple lists in one view. There are also statistics reports to record chore completion history. With separate purchase of Chore Checklist Cloud Connector, the full version users can also sync/backup to cloud and share their lists with other users.
We also provide free online editor at www.dotnetideas.com for easy list editing.
See Help in app for more detailed instruction.

This app is only compatible with certain phones, it's hard to give a list without having every phone for me to use, it was developed on HTC Desire bravo and works daily for me, as I only have one phone testing on other devices is limited.
If you encounter issues please do let me know and i will add it to the non supported phone list
Not compatable with HTC one and other 1080 screen phones as far as i know
ALSO YOU MUST HAVE AN EXTERNAL SD CARD WITH SOME FREE SPACE TO USE
The log book is very safe and secure, it can easily be got from the phone on your sd card, or emailed
to you by the in app email me function.
Note as our log books are so valuable if this app is removed by accident you will loose you data, planes etc but not your logbook.
All the features have been well tested however the Watcher function that monitors for when you go flying is very experimental,
It depends on your gps being on and having a good wake up time.
If you find you battery drains quickly then change the 'Watcher Frequency" it is set by default to 120 seconds ie look for take off / landing every 2 mins, however I find 200 is enough.
This app has a multitude of settings and preferences, most you don't need to use but I believe in letting you change any settings you want in an app.
GPS Watcher - The GPS watcher service is an experimental feature that uses conditions, parameters and an every increasing in complexity algorithm.
The GPS watcher runs in the background in sleep mode waking up every 3 mins (user configurable) to see what the gps reads in relation to altitude, ground speed, ROC/ROC, location and location change to name but a few to (try) and detect take off and landings, these can then be viewed or by adding Aircraft reg be added to the inbuilt log book.
There are a number of settings in the Preferences to tweak it so it works better for you.
The MOST IMPORTANT is height set it to 400ft above you normal airfield elevation
Best to open the manual and see the section on the Watcher to find what to set them to.
There is a growing user manual at www.TargetAviation.co.uk/PilotPal/Manual.htm
There are no adds and there is no charge for using this app if you like it, I am a full time commercial pilot not a software developer so while I'm happy to support it, it will be limited!
What permissions – why ?
Location – GPS is only used if the GPS watcher is turned on to detect flights
Storage – sd card to store your aircraft, airfields, preferences and logbook
Network / internet – To email your log book to you, get weather info TAF Metar and rain radar – if off phone cloud backup of you logbook is on then that too
System tools – prevent sleep – on the In Air Display screen showing track, ground speed, lat long ROC/ROD etc the screen will not time out
Supports portrait and landscape orientations.

Welcome Goal Achiever!
This Apps' mission is to encourage, support, and reward you for taking meaningful daily action towards the attainment of your goals, big or small. To help you take consistent action long after the excitement you felt when you committed to a worthy goal has faded.
One of the reasons you might not be successful at reaching a goal is because you did not take consistent and sustained action for a long enough period of time.
This checklist was especially created to help you take daily consistent action over time.
"For changes to be of any true value, they've got to be lasting and consistent." - Tony Robbins
"...we have to make good decisions, use discipline and be consistent for long enough to see the results we desire." - Darren Hardy
The idea is simple:
1. Enter the actions you know you have to take daily to reach a goal. Like: Workout for 40 minutes, make 10 cold calls to prospective customers, send out 10 resumes to potential employers, write at least 10 pages for project, etc.
2. Put the widget on your home screen. When an action is not yet completed it shows up in bright colored text. Once you check an action off the list the text becomes a lighter color.
3. Your daily mission now becomes to see the list go from bright (in the morning) to gray (before going to bed). You can instantly see how far down your action list you are at a glance. This color change also signals that you had a successful day. A day in which you accomplished all the actions you needed to take you one day closer to your ultimate goals.
A successful day, with all items checked, results in a green check mark placed on the calendar. Watching a series of check marks fill up the calendar, helps motivate you to stay consistent.
There is an indicator on the main list screen that shows the number of consecutive successful days. This is your success streak. A streak with seven or more days turns this indicator green. This gives additional motivation for consistency.
The home screen widget also serves as a constant reminder of the actions you need to take today. Each time you use your Android device you'll see the list and the amount of actions remaining.
In short: Don't go to bed if your list is not completed. If bedtime is near and your list is not close to completion, get to work on what is left on the list!
If you have any questions or comments send an email to:

More from developer
I have developed it because I couldn’t find any free flashlight in the “Android Market” without advertising and without abusive permissions.
Why does a flashlight app need permissions to access internet?
Or to read your SD card?
Or to read your phone identity?
Or to know your location?
QR Flashlight does not need any permission. Also QR Flashlight does not stay in the memory as task when you exit it. No need to stay open, using memory space and resources. No “task killer” needed to close it.
QR Flashlight is only 158 kb. It does not need any more to fulfill its mission.
If you are looking for a simple free application in the market, without advertising and without permissions, in any category and you can not find it, please send us a suggestion to email@example.com

Designed by pilots for pilots.
It covers all the aspects of Flight Planning:
- Weight and Balance
Calculates weight and balance based on the POH. Displays results on a graph. More than 20 popular planes in our database. You can also add more or send us a request to add yours.
- Fuel management
Fuel calculations are very precise. They are based on the performance charts of your POH, with the fuel flows during climb, cruise and descent corrected for altitude, pressure, temperature and wind.
- Operational Flight Plan
We obtain the true heading, the magnetic heading and the distance for each leg of the flight plan, corrected for wind, pressure and temperature. The drift is calculated. If we change the aircraft, the flight plan is recalculated automatically to the new performance. Performance charts for several general aviation planes are already loaded. The waypoint database includes more than 120.000 points worldwide. It also includes the coordinates for 18.000 Spanish villages and towns. Practically all airports, including ULM
- Flying the route with moving map with aeronautical charts
The Flight Plan is plotted in Oruxmaps (www.oruxmaps.com) and using the phone's GPS we see the route in a moving map. You can scan the chart you carry on board and use it as a moving map. VFR and IFR charts for the US are available on line. Oruxmaps allows you to download them and use them off-line in the aircraft.
- Downloads Aviation Weather Information Metar and Taf,
It automatically selects the Weather Stations more convenient to your route from the Weather Database already included. It fetches for you the last report.
- Downloads Aviation NOTAM
The app automatically selects the NOTAM need for your route and downloads it.
- To report errors, make any enhancement suggestion or get quick and friendly support, please send us an email to firstname.lastname@example.org

The game has two modes:
- One Million
You can use it to pop the bubbles at your own pace. There is a counter showing all the bubbles popped from the installation of the game. You may upload the number of bubbles you have popped to a Score Board in the cloud. Let’s see who is the first one in the world to burst one million bubbles.
- Time Trial
Pop the bubbles against the stop watch. Dare your friends to see who is faster. You can configure the competition bubble wrap sheets from 50 to 500 bubbles. Your best times records are uploaded to a Score Board in the cloud (Internet permission is needed for this).
Pop the bubbles as fast as you can and beat the scores of your friends or of other people in the world!
All the bubbles you crush in the “Time Trial Mode” are also added in the counter toward the “One Million Bubbles”
Permissions: Internet Access to upload and download your scores to the Score Board.
No other permission required. This app does not have any ads. No spyware. It does not have permission to read your SD Card. Your data is not going anywhere. It does not read your phone identity either. It has very small footprint and memory usage.
