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.

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

Why another GPS logger?
This logger is optimized for battery life. You can select a gps interval and between these events gps will be completly disabled.
Therefore, it is especially suitable for very long tracks (hiking, trekking, sailing, biking,...) or to track a phone (track your childs).
You can check the points on a map or you can send them by mail (smtp account). The mail from the phone includes timestamp and a google map link for each GPS point.
Additionally you can generate KML- and GPX-files, store them on sdcard and send them as mail attachment.
You can define gps accuracy, min log distance, pause intervals and much more.
This pro version is a donate app, if you like the app, spend me a beer.

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

The graphical interface is very simple and easy to read in the plane. The checklists are organized in four levels. No other app in the market has four levels, needed in aviation.
Of course beside aviation, the app can be used for any other purpose where organization in four levels is needed as well as an easy transfer between phone and personal computer. Yeno Checklist XML files are also compatible.
The first level is “Aircrafts”. You may have items like
The second level is “Checklist Groups”. For each aircraft you may have items like:
The third level is “Checklists”. For each “Checklist Group” o procedure you may have items like:
Finally the fourth level “Tasks” may have items like:
“Flaps as Required”
“Propeller Full Forward”
Even though the user-friendly interface of the program allows you to directly create your checklists in the phone or tablet, for your convenience, you may download this desktop application for free from:
This program allows you to create or modify the checklists faster at your windows-based home computer (Apple and Linux apps will follow shortly).
You can transfer your checklists between your computer and your phone or tablet simply copying the database file (“AvChecklist.db”) or exporting and importing to an XML file.
Previous Yeno Checklist’s XML files are also compatible.
You can also upload and download checklists from the internet to easily share checklists between users or to transfer your checklists between the home computer and your Android device.

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.
