If you encounter any problems using one of the Flite applications, please refer to the online help pages as first priority. Each screen provides a help text that can be invoked by tapping on the small 'i' in the top right corner.
If the situation is still unclear, try to get the most recent version of the application on the respective page and try again.
The following FAQ then lists some questions that have been asked.




What is a HotSync ID and where can I get mine?
The HotSync ID is a unique name you gave your Palm device on initial installation. In order to retrieve it, call the HotSync application from the 'System' category on the handheld. Your ID is then in the top right corner of the screen.
Alternatively, your HotSync ID is displayed on the registration form of any Flite application that must be registered, written in bold between the 'Enter key for HotSync ID' text and the field for the key entry. In the following example, the HotSync ID is 'Christoph Regli':

HotSync ID.

The correct submission of the HotSync ID is crucial for registration key generation, especially concerning small and capital letters and blanks. Note that the HotSync ID can be empty.

How can I switch off the Palm system sounds in order not to disturb my environment when using Flite?
Start the 'Prefs' application ('Einstellen'), go to 'General' ('Allgemein'), and select 'System Sound' ('Systemsignal') to 'Off' ('Aus').

Where can I enter or modify values?
As a general Palm OS user interface design guideline, whenever there is a grey or dotted line, you can select or modify a value. Triangles denote a popup list.

How can I determine the version number of the installed application?
Simply press on the small Flite arc at the bottom of the screen, or press the menu button and select 'Options', 'About'.
The Excel sheet of the FliteLX application has a release date instead. This date is written on the 'Help' page.

Are the programs available for Windows CE / PocketPC / Psion / ... PDAs?
No, they are not. It takes quite an effort migrate software to a new operating system. Especially on PDAs where the screen size is rather limited, the possibilities of the user interface drive the design of an application, so the existing Flite software would have to be re-designed. I prefer to invest my time into the current target operating system.




Which fleets are supported by the hold over time decoder?
Currently, the HOT tables of the Embraer 145 were implemented, only minor differences have been noted to the Jumbolino HOT tables. A comparison with the tables of all other fleets has to be done yet. It is therefore not intended to be used operationally.




I installed the database files but there is no icon on the application launcher, and FliteLX reports "The FlitePilot application has not been found." when I press the button with the phone receiver symbol.
Besides at least one of the database files ('Pilots.pdb', 'OM.pdb' or 'Schedule.pdb'), you need to install the application file itself ('FlitePilot.prc'). Refer to the FlitePilot section to get this file.

What means 'No database file was found.'?
The FlitePilot application is a database viewer for currently three different databases: The seniority and phone numbers list, the OM-A reference, and the Swiss International Air Lines timetable. It won't start up if there is not at least one of these database files installed. Refer to the FlitePilot section to get these files.




Please refer to the manual.

How can I enter data on the desktop PC?
It is not possible to enter data on the desktop PC; everything has to be entered on the Palm handheld. The 'FliteLX.xls' Excel sheet only displays the content of the Palm databases that are copied onto your desktop PC during a HotSync process. So do not modify an Excel sheet manually as the totals and forwards won't be computed correctly.
It is possible however to import the duty plan. Refer to the respective section of the manual.

Are there any tips on how to efficiently use the loadsheet application?
Clear the loadsheet fields by pressing the 'C' button first. Then start at the very top of the 'Payld' page and work from top to bottom. Enter the passenger figures prior to entering the class distribution. This is due to the fact that the loadsheet applications do not accept a class distribution with zero passengers, it always assures the integrity of the data. Some values may modify other values that appear later in the sequence: If you modify the passenger total, the service index adjustment will be influenced if enabled e.g., or the fuel burn adjusts automatically to being lower or equal the block fuel.
It may be helpful to select the number in a field and then to overwrite it: Simply tap at the beginning of the number and move the pen to the end of the field. Alternatively, tap on the label of the field.
Finally, after having had a glimpse at the 'Env' page, press the '?' button.

Why do infants not have a mass any more?
Prior to the OM-A revision dated 2002 October 27th, infants occupying a separate passenger seat had be calculated with a mass of 11kg, while infants carried by adults are included in the passenger mass of the adult (former OM-A, article).
Now however, this 11kg article does not exist any more, so infants do not influence the total mass.

How can I use the service index adjustment?
As soon as the checkbox is ticked, any passenger total will influence the service index adjustment. However, you can manually enter any service index mass or index. The application then calculates the other value.

The baggage and cargo indices differ for the same mass value. Why that?
This depends on the total loading in the cargo compartment. If you have say 12kg of baggage, you get a baggage index of 0. When you add 1kg of cargo, this kilogram leads to an index of 1.

What can I do when an aircraft immatriculation is not yet on the list?
Enter the BOM/BOI manually. The BOM/BOI is the DOM/DOI excluding the catering.

Why do I have two 'Ballast' fields, one on the 'Payld' page and the other one on the 'M&B' page?
On the 'Payld' page you enter the mass of the ballast in the cargo compartment, while the ballast field on the 'M&B' page denotes the amount of fuel used as ballast. Refer to the next question for further explanation.

What is the purpose of ballast fuel?
Ballast fuel can be used if the aircraft is light, e.g. on ferry flights, and the zero fuel point is below the flight envelope. Thinking of loading ballast into the cargo compartment in order to resolve this situation, it turns out that the zero fuel point moves parallel to the ballast trend vector, i.e. more rightwards than upwards, so never joining the flight envelope when loading ballast into the cargo compartment.
The fuel trend vector shows the movement of the points when changing the amount of fuel on board. Now, the zero fuel point is per definitionem at the very bottom of the fuel trend vector, with zero fuel. This is where the ballast fuel plays its role: The zero fuel point here includes the ballast fuel.
Note that in this case the operational block fuel calculation must NOT include the ballast fuel; the zero fuel point would move outside the flight envelope, should any part of that ballast fuel be burned.

Why is the observer part of the DOM and not listed under traffic load as on the manual loadsheet?
Because the observer is part of the crew required to operate the aircraft and therefore not part of the payload. There are no guidelines on how to calculate the mass and index of a passenger on the cockpit jumpseat - passenger masses differ from the crew mass (90kg).

What are the reasons for the discrepancies between the DCS loadsheet and the result of the loadsheet applications?
The two reasons are a) DCS loadsheets consider seven trolleys as standard, i.e. without the indication of a DOM/DOI, the number of trolleys is 7. b) In contrast to the manually calculated loadsheet, which leads to the same result as the Flite loadsheet programs, the DCS loadsheet is based on seat row trim, whereas loadsheet applications implement the class trim according to the PIH.

Why doesn't the application make a suggestion on how to change the cabin version if the envelope constraints can be met by doing so?
In order to meet the envelope constraints by changing the cabin version and/or passenger class distribution it is crucial to re-seat the passengers accordingly. It has been decided to lower the priority of this possibility so the pilots are not tempted to changing it on the paper only.
