Information added in the field Pilot notes also will appear on the Trip Sheet, in the section 'Pilot Notes'.

Tower hours shared.png

If you hover the mouse over it you will see a message Click to make this field private which means that no-one apart from you can see added information. If you go for private option the icon will turn to Do not share.png. You can always undo that action by clicking on this icon again.

Timezone and Time format options

When editing Control Tower Hours field you can choose the timezone for opening hours between Local Time (LT) and UTC (Z). The zone highlighted blue is the zone that applies to Opening Hours.

Leon will not recalculate the times in Control Tower Hours automatically. Airport opening times will be checked when adding a flight based on the information in this section.

In the Control Tower Hours window you can see 3 columns, as presented in the screenshot:

  • Opening hours - here you can input either specific times “From - To”, or in Sunset/Sunrise Format which is explained further in this section, for each day of the week.
  • 24H - a checkbox that allows you to mark an airport being open for 24h on a specific day. Ticking this checkbox will turn “Opening hours” columns grey.
  • Closed - this column allows you to mark an airport being closed on a specific day. I you untick the checkbox Leon will react with accordance to previous hour setting. Most of the time unticking “Closed” checkbox will automatically tick “24H” checkbox, unless Opening hours were input manually. In this case unticking “Closed” checkbox will edit “Opening hours” column.

As you can see in the screenshot, there are two input formats in Control Towe Hours that you can use:

  • Standard HH:MM format
  • Sunrise/Sunset format where SR stands for Sunrise and SS stands for Sunset

Sunset/Sunrise format allows to input Control Tower Hours based on time (in hours-h or minutes-m) before/after Sunset or Sunrise.

For example if an airport opens 30 minutes after sunrise and closes 2 hours before Sunset, its opening time in Control Tower Hours field would be SR+30m and its closing time - SS-2h. Example of input in screenshot below

When the flight is scheduled to take off or land outside permitted hours the following message will display: Departure (Destination) airport is closed at the time of departure (arrival)

Approved handling/FBO agents

Approving handling agents

It is possible now to set the approval date of the handling agents or FBOs in Leon. Leon will send an email notification at 00:00 every day to the inserted email address, if the expiry date has passed.

  • ELEV
  • Terrain
  • Weather
  • Ground facilities
  • Special considerations

If you want to add an 'Airport brief' to Leon, mark the checkbox Airport brief available and if necessary set the expiry date and upload a file.

  1. Tick the Airport briefing available checkbox. This opens the section where you can prolong Airport Brief.
  2. Click Prolong button to open the Calendar.
  3. Choose the date and accept it by clicking OK button.

Online familiarization

If required, you can add Online Familiarization for a crew member in 2 ways:

  1. Airport Directory - edit section 'Brief / Training' and mark a checkbox Online Familiarization Required.
  2. Personal Endorsements - edit user's profile and in the tab Online Familiarization add airport code. After updating it you can add more details of the online training: number, issue & expiry date, notes, pdf scan.

In a section TABLE Leon highlights crew codes in when option 1 is added. Hover the mouse over the code to get a pop-up window with an information (see below).

online familiarization.jpg

In a section OPS an airport with marked 'Online Familiarization' is framed - when you hover the mouse over the code you will see a notice “Airport recency required”, “Online familiarization required”.

Airport Recency

You can also add an information to Leon if a particular crew member needs a Airport Recency (either on the aircraft or simulator).

Just like with 'Online Familiarization' - you can add a Airport Recency either from 'Airport Directory' by marking a checkbox Airport Recency or from Personal Endorsements, tab Airport Recency.

Option for Flight Support Companies

If you are a Flight Support Company which deals with aircraft chartering, aviation services, consulting, etc. and you want changes in Airport Directory sections: Brief/Training or Category to be applied also to operators using your 'Airport Directory', you can simply mark a checkbox Apply changes to all operators using (name of your operator) Airport Directory.

In other words - if you change i.e. Airport Category in you Airport Directory for airport LTN from A to B and that checkbox is marked - all operators you deal with will be affected with this change.

Adding new Handling Agent/FBO

Adding a new handling agent into Airport Directory

To add a new Handling Agent/FBO to an airport in Airport Directory, you have to go to Handling/FBO tab and click on Add new button. This will open Add new handler field where you can input the details of the new handling agent.

Fields “Name” and “Email” are mandatory. If Name field is empty, Leon will not save the handler. If Email field is empty while trying to save the handler, Leon will display error message that says: Error: Email field cannot be empty.

Once the mandatory fields are filled in, you can click on one of the buttons located at the bottom of the page: ✔ will save the listing, ✘ will cancel it.

Saved Handling Agent will show at the bottom of the list and the listing will have a different background.

It is also possible to delete personal Handling Agent/FBO. In order to do it you have to click on a handler you would like to remove and press Delete button. This gives 2 options, why the handler is being deleted:

  • Entry does not exist any more - this will remove handler
  • Duplicate - this will open a dropdown window with names of handlers that could be duplicats of listed handlers.
It is not possible to remove a Handler/FBO imported from AC-U-KWIK software - only those added manually can be deleted from Leon
