Thank you for having chosen FlyPrep!

FlyPrep assists you with the flight preparation as well as during the flight.
You can do the flight preparation in front of the aircraft with the exact weights of the passengers and baggage, and the correct amount of fuel in the tank.

FlyPrep lets you plan and save routes. The selected route is displayed in the airfield view amongst the airfields, the airspaces, the navigations aids and other aircrafts with active FlyPrep or FLARM2. FlyPrep gives a warning if there is a probability of a collision with another aircraft and alarms if a collision is very likely.
The runways of the airfields are displayed true to scale in length and in the true direction.
For the event of engine failure during the flight, FlyPrep helps you in estimating if a surrounding airfield can be reached gliding.

FlyPrep lets you manage your own aircrafts. The data of the selected aircraft is used in navigation and in flight preparation and flight information dialogs.


FlyPrep is only intended to be an add-on to the compulsory flight preparation and flight execution! The collision warning system only provides additional information, you have to look out and decide yourself!


FlyPrep has been created with the greatest care. Nevertheless, it is not guaranteed to be error free. Always check the plausibility of the given information.

Remark: All values shown in the dialogs in this manual are examples.

Introduction

For flight preparation, FlyPrep provides the calculation of the planned TAS, MACH#, MH/HDG and GS; the required IAS, TAS and MACH#; the required amount of fuel; and the Weight&Balance.
During the flight, FlyPrep provides the calculation of the current TAS, MACH#, GS and wind; and the fuel consumption, the distance flown, the flight leg, the Point of No Return and the Equal Time Point.
The calculation of the endurance, the pressure altitude and density altitude is useful before as well as during the flight.
For the weather trend it is important to calculate the cloud base and the dew point.

In the navigation of FlyPrep you can plan your routes graphically or via the route dialog that includes an airfield search. Waypoints are set graphically by dragging the displayed route on the waypoint. The route dialog lets you save the displayed route and you can load and activate it for another flight.
In the airfield view, FlyPrep displays along with the active route, the airfields, the airspaces, the navigation aids and the aircrafts with active FlyPrep or FLARM2. FlyPrep gives a warning if there is a probability of a collision with another aircraft and alarms if a collision is very likely.
The runways of the airfields are displayed true to scale in length and in the true direction.
For the event of engine failure during the flight, FlyPrep helps you in estimating if a surrounding airfield can be reached gliding.

Usage

After the start the initial display of FlyPrep is displayed:

StartDialog

At the top the selected aircraft is displayed and, in case you are airborne, the 'In Flight' indicator. How you select an aircraft is described in chapter Aircraft.
FlyPrep knows when you take off and land and sets the 'In Flight' indicator accordingly. In case you activated FlyPrep after takeoff or you do not want to log the flight, you can manually change the 'In Flight' status in Settings.

Below that there is a row with buttons in the flight preparation, flight information and aircraft dialogs. The Reset button is described in more detail further down in this chapter. The Set button and the context help link are only displayed in the flight preparation and flight information dialogs and are described in more detail in chapter Flight preparation and Flight information.
In the aircraft dialogs, the aircraft being edited, the New and Delete buttons are displayed instead of the selected aircraft and the Set button. These are described in more detail in chapter Aircraft.
Aircraft

In Navigation, Settings and Help no button row is displayed.

At the bottom of the screen is the menu:

Menu

With the menu you can swap between:
FlyPrep displays the four dialogs for the Flight preparation and Flight information. These dialogs provide all calculations of FlyPrep.
Navigation displays the airfield view, the map view and the flight log of Navigation.
Aircraft displays the three dialogs for the Aircraft being edited. In these dialogs all data for the aircraft are entered and displayed respectively.
Settings displays the two dialogs for Settings. In these dialogs you can change the general settings and the settings for the navigation.
Help displays the help system and the About information in two views.

In the middle of the screen are the dialogs and views respectively of FlyPrep.

In case FlyPrep gets interrupted, e.g. by an incoming call or pressing of the home button, the collision warning system and the GPS location service continue to run in the background for 10 minutes(iOS6) and 3 minutes(iOS7) respectively. In case FlyPrep calculates a collision probability during this time span, it displays the collision warning or the collision alarm as notification, plays the warning or alarm sound and shows a '1' in the icon.
Badge
If you activate FlyPrep through the notification, FlyPrep will display the collision warning or the collision alarm immediately (see collision warning system). Please refer to your device handbook on how to handle and configure notifications. Never switch off the FlyPrep notifications in the notification center!
If you activate FlyPrep when it's still running in the background, FlyPrep resumes its work without losing GPS precision.
Without activation FlyPrep switches the collision warning system and the GPS location service off to not drain the battery.

Number panel

The Number panel appears automatically when you tap on an input field in a dialog:

Number panel

For entering a value in an input field you tap on the corresponding input field. This input field is highlighted in orange and the Number panel is displayed half transparent on top of the dialog.

Collision warning system

The collision warning system of FlyPrep communicates with other aircrafts with active FlyPrep or FLARM2. If you are airborne, FlyPrep calculates the collision probability with the surrounding aircrafts. For that calculation FlyPrep considers the aircrafts in a radius of 60NM of your current position. If the calculated collision point is within 1-3 minutes of your current position, FlyPrep gives a warning. If the calculated collision point is less than one minute of your current position, FlyPrep gives an alarm.
In case of a collision warning FlyPrep does the following:
- displays the airfield view in Navigation, centers it to the GPS coordinates and adjusts the zoom level
- plays a warning sound
- displays the causing aircraft yellow
- displays the backgrounds of the selected aircraft and the menu yellow
Collisions warning

In case of a collision alarm FlyPrep does the following:
- displays the airfield view in Navigation, centers it to the GPS coordinates and adjusts the zoom level
- plays an alarm sound
- lets your iPhone vibrate
- displays the causing aircraft red
- displays the backgrounds of the selected aircraft and the menu red
collision alarm

For the communication with other FlyPrep users FlyPrep needs an existing internet data connection. In case your device does not have data connection, the positions of your own and the surrounding aircrafts cannot be updated. Aircrafts with no position update for more than 1 minute are classified as indefinite and will not be considered anymore in the collision warning system. They will be deleted from the views.

Flight preparation and Flight information

In these dialogs you can do all the calculations for the flight preparation and flight information.

Dialogs

There are four dialogs: You can scroll between the dialogs with single swipes to the right or to the left, or by tapping left or right of the page control.

For each dialog the selected airplane, the Conversion button, the Reset(R) button, the Set button, the context help link and the Calc button are displayed.
With the context help link FlyPrep jumps to the section in Help explaining the calculation for the displayed dialog.

Set button

Set
In case you selected an aircraft and/or GPS data is received, the Set button sets all relevant values of that aircraft and/or from the GPS in the active dialog.
The values that can be set are described in each dialog's description.

Calc button

Calculation
Pressing the Calc button triggers a calculation. In the dialog Weight&Balance it leads to the calculation of the total weight, the centre of gravity and the total moment. In the dialogs Wind&Course, Altitude&Speed and Fuel&Distance the calculation depends on the given input values. In the description of these dialogs the calculations table shows which input values are needed for which calculation. When there are more input values given in a dialog than are needed for one of the calculations, all calculations of a dialog have different priorities. These priorities are shown in the calculations table in the respective dialogs as P1, P2, and so on where P1 has the highest priority, i.e. P1 is executed before P2, P2 before P3, and so on.

Example: You would like to calculate the planned MH and the planned GS:

Navigation

In the navigation of FlyPrep you can plan your routes graphically or via the route dialog that includes an airfield search. Waypoints are set graphically by dragging the displayed route on the waypoint.
In the airfield view FlyPrep displays along with the active route, the airfields, the airspaces, the navigation aids and the aircrafts with active FlyPrep or FLARM2. FlyPrep gives a warning if there is a probability of a collision with another aircraft and alarms if a collision is very likely.
For the event of engine failure during the flight, FlyPrep helps you in estimating if a surrounding airfield can be reached gliding.

Navigation

There are three views: You can scroll between the views by tapping left or right of the page control.

Airfield view

NavAirfield

The airfield view displays at the top the current altitude, the current true track and the current ground speed.
At the left bottom corner the vertical and horizontal resolution of the view is displayed. At the middle bottom is the page control which you can use to swap between the airfield view, the map view and the flight log. At the right bottom the latitude and longitude of the center of the view are displayed. Both values are editable, i.e. tapping on the value activates the number panel the value can be changed. After the change the view is centered automatically to the new coordinates.
The following is displayed in the view:
NavAirfieldDetail
For grass runways, the runway and the name of the airfield are displayed in green, for sand runways both in brown, and for solid runways both in black.
The minute line indicates where the airplane will be in a few minutes. It is divided into minute segments and shows maximum 5 minute segments. Depending on the plane's speed and the resolution of the airfield view fewer minute segments may be displayed.

The red and blue connection lines from your aircraft to the surrounding runways help you in estimating if you can reach these runways gliding in case of an engine problem. The red line is the direct way from your current position to the middle of the runway. The blue part on this line marks the estimated glide distance. Prerequisite for this calculation is a selected airplane with given correct glide ratio and speed for maximum glide. When the blue part is far away from the airfield, you cannot reach this airfield by gliding. Even if the blue part touches the airfield, it is not guaranteed that you can reach the airfield by gliding. This depends on the wind, on the weather, on the surrounding terrain and how well you maintain the speed for maximum glide. In case the actual wind (wind direction and wind speed) was calculated with FlyPrep and the speed for maximum glide for the aircraft was entered, these will be taken into account during the glide path calculation.

How the collision warning of the surrounding aircrafts functions, is described in chapter Collision warning system.

The view contents can be scrolled like a map. Double tap or pinch open for zooming in, two fingers tap or pinch close for zooming out. The display of the vertical and horizontal resolution and the coordinates for latitude and longitude are updated accordingly.
A triple tap anywhere in the view centers it to the current GPS coordinates.
A long tap invokes the route popup. If the tap was on an airfield the ICAO code and name of the airfield are displayed at the popup top. If the tap was on a navigation aid the ICAO code of the navigation aid is displayed. Otherwise the latitude and longitude of the tap position are displayed. At the popup bottom the airspace with its limits is displayed for the tap position.
Examples: At the popup center are buttons which:

You can delete single flights in case after you transferred them to your flight log document. To delete tap on the flight and then on Delete of the selected flight.

Contents

Aircraft

In the aircraft dialogs you can manage your aircrafts. You can create a new aircraft or modify or delete an existing one.
For the name you can use the aircraft's call sign (e.g. N765FL) or the aircraft type (e.g. Cessna 172) or a combination of both. Up to 50 characters are allowed for the name.

Aircraft

There are three dialogs: You can scroll between the dialogs with single swipes to the right or to the left, or by tapping left or right of the page control.

For each dialog the aircraft being edited, the Conversion button, the Reset(R) button, the New button and the Delete button are displayed.

To create a new aircraft enter the name in the field 'Aircraft' and the values in the three Aircraft dialogs.
To modify an aircraft select the desired aircraft from the aircrafts list (field 'Aircraft') and modify the incorrect values or add the missing values.
Modifications and additions to an existing aircraft are saved immediately. A newly created aircraft is saved automatically upon leaving the aircraft dialogs.
To delete an aircraft select the desired aircraft from the aircrafts list (field 'Aircraft'). Pressing the Delete button will delete the aircraft.

The data of the last selected aircraft will be used in the Flight preparation and Flight information dialogs to set relevant values with the Set button and in Navigation to calculate the glide path.

Weight

In this dialog you can enter the weight of the empty airplane and the arms of all weights.

Weight

In the weight values for Fuel, Pilots, Passenger and Baggage you can enter the corresponding maximum permissible limits. The weights entered in the dialog Weight&Balance are checked against these limits during the calculation of the total weight and if a weight value violates a limit, the calculation is invalid.

Contents

Centre of Gravity diagram

In this dialog you can create a centre of gravity diagram from the centre of gravity limits defined in the flight manual. To do so, enter in order the pairs of value for the points of the centre of gravity limits.

Centre of gravity

By default the pairs of value are arranged as Weight and Arm. In case the pairs of value in the flight manual are given as Weight and Moment you can change the input by tapping on 'Arm' to 'Moment'. This adjustment will be stored with the airplane and taken into account during the checking of the centre of gravity in the dialog Weight&Balance.

The correct way to fill the rows is: Enter in the top row the lightest, most front centre of gravity limit, in the second row the clockwise next centre of gravity limit (second lightest or second front) and so forth until you reach the first centre of gravity limit again.
Example with six value pairs:

Schwerpunktdiagramm
Pressing the Draw button draws the centre of gravity diagram according to the entered values and you can check if the drawn one corresponds to the one in the flight manual.
In the dialog Weight&Balance it is checked during the calculation of the centre of gravity, as to whether it lies within this centre of gravity diagram.

Draw button

Draw
Pressing the Draw button draws the centre of gravity diagram according to the entered values.

Contents

Misc. Values

In this dialog you can enter the usable fuel capacity, the average fuel consumption, the normal cruising speed (TAS), the glide ratio and the speed for maximum glide.

Misc.Values

The glide ratio and the speed for maximum glide are used in Navigation in the airfield view to calculate the glide path.
