About VFR Course Calculator
The VFR Course Caclulator calculates true heading, magnetic heading & course, compass heading & course, wind correction angle, cross wind and headwind by entering the true course, wind direction and speed, true air speed, variation and deviation. Further it is possible to calculate the flight time (TL) for a distance in dependance of groundspeed. Based on these values it calculates fuel demand and weight if you enter the consumption (flow) and fuel density. It does not matter which field you use. The app will automatically convert the entered data in metric, US and UK unit system. The app converts NM (nautical miles), SM (statue miles) an KM (Kilometers) instantly. You can switch in the results for ground speed (GS), cross wind (XW) and head wind (HW) between knots (kt) or kilometres per hour (kph)
True course, true heading, wind direction and wind speed is visualised with a vector (TC), aircraft symbol (TH) and wind barb (WD & WS).
If you want to calculate only the flight time and/or fuel and know your groundspeed, just put your groundspeed into field "true air speed" and enter flight distance "distance leg", fuel demand (burn per hour) and fuel density. Leave the other fields empty.
This app is useful to pilots and aircraft apprentices for planning your VFR flight fast and easily.
App is running natively on iPhone and iPad.
The app is completely written in LiveCode.

V 1.6.1: Minor bugfixes which missed to fix in V 1.6.0. See below for new features in V 1.6.0
V 1.6.0:
1. Now there are input fields in kph (km/h) for wind speed (WS) and true air speed (TAS) with auto conversion to knots (kt) and vice versa.
2. You can further switch between knots (kt) and kilometres per hour (kph) in the results for ground speed (GS), cross wind (XW) and headwind (HW).
3. For distance leg (DL) there are additional input fields for kilometres (KM) and statue miles (SM) with auto conversion to nautical miles (NM) and vice versa.
4. Bugfix for crashed graphics on iPad (landscape mode for the moment disabled, need some more adaptation first) and some issues with restoring the entered values when bringing app back to foreground.

Fixed a bug which in some cases leaded to an incompletely restoring from the entered data when bringing app back to foreground.
Added "Information"-Button which show up (offline) the Privacy Policy from the App according to DGPR.

Added support for iPhone X Display. For iPhone X users there is an UTC clock on the top of the screen.
Last used parameters are saved and restored when closing and reopen the app or switching to another and back.
(If app is not used for more than 15 Minutes values will be reseted on next start)
Minor optimisations in the code and design.

New App-Icon!
Visualisation of true course (TC), true heading (TH), wind direction (WD) and wind speed (WS) added.
The vector stands for TC, the aircraft symbol for TH and the wind barb for the wind direction (WD) and velocity (WS).
Code optimization:
- Input fields now accepting only numbers.
- Comma (,) is autocorrected to dot (.), (this is needed to prevent wrong calculations internally).
- Courses and angles bigger than 360° are corrected to courses equal or less 360°. (e.g. 720° is automatically corrected to 360°)

Fuel calculation and instantly conversion for metric, US and imperial units added. Input your values in one of the three fuel fields (consumption and density) and the other will convert instantly.
To switch between metric, US and UK units in the results just tap on the option button.
You can know reset the values by tapping twice on the titlebar or shake your device. Easier when working an iPad.
Some design optimisations.
