MEL CDL Assignments
The purpose of this program is to allow the operator to assign outstanding maintenance (MEL/CDL) items against a particular airframe so that whenever that aircraft is used by the Flight Plan program, the list with its corresponding descriptions will be displayed for the dispatcher.
We estimate that this will take 1 minute to complete.

MEL CDL Assignments
The purpose of this
program is to allow the operator to assign outstanding
maintenance (MEL/CDL) items against a particular airframe so
that whenever that aircraft is used by the Flight Plan program,
the list with its corresponding descriptions will be displayed
for the dispatcher. When an aircraft is scheduled for a flight,
the dispatcher can review the list to see if there are any
operational restrictions that may have an impact on flight
planning. For instance, some defects may impose a limit on the
maximum altitude to which the aircraft may be flown, and this
should, of course, prompt the dispatcher to cap the flight level
used by the Flight Plan.
The program automatically sorts the codes that are operational to the top of the list, and keeps track of the dates of all such entries so the age of any item is always available.
You can make MEL and CDL penalties using this menu and the MEL/CDL Dictionary screen.
the aircraft ID number. The program will verify that the
aircraft you entered exists in the Aircraft Characteristics
file, and will display the appropriate aircraft type. An error
prompt will be returned if the ID number is not in the Aircraft
If you attempt to add an aircraft ID number for which an aircraft already exists, you will be so advised. Similarly, if you attempt to Edit an Aircraft ID number that has not already been Added to the file, you will be given a Record Not Found prompt.
If this is the first time that entries have been made for a particular Aircraft ID number, then you may enter MEL/CDL codes. If you wish you may exit at this point without entering any codes; this allows you to open records for all aircraft in the fleet regardless of whether they have any outstanding items or not.
Equip/Series/Engine: These fields automatically load when an Aircraft ID is entered.
The Add mode is intended to provide a means of opening new records for new aircraft. Once a given ID number has been added, all other transactions to do with the aircraft, e.g., adding new MEL items, or removing others, should be handled with the Edit mode.
MEL/CDL: Choose MEL or CDL.
Num: Choose a number, you can only select numbers that have been added in the MEL/CDL webFOMS screen.
Description: This is automatically populated when you select a number.
Operational/Restrictions: Operational field auto-populates (checked or unchecked) based on whether the MEL or CDL item is set to operational or not. The Restrictions auto-populates (checked or unchecked) based on whether an MEL or CDL item is restrictive or not.
DMI: DMI (deferred maintenance item) number as per MEL list for that aircraft type. You must assign a different DMI number for each instance in order to assign multiple MEL items with the same number to the same aircraft.
Expiry/Extension/Updated: The Updated field auto-populates with the current day/month for which the MEL or CDL item was added or updated. Cursor then takes you to the second line where you can enter an expiry date.
Operating Count/Age: The age value defaults to zero when an MEL or CDL item is first added. This field shows the number of days since the MEL was first assigned to the aircraft. CNT/Op. Count value is the catalyst that decides whether or not a penalty will be applied. If the CNT/Op. Count value matches the value entered in the operational condition flag in the MEL/CDL Dictionary screen for that MEL, the penalty will be applied to the flight. If a value lower than the operational condition is entered in the CNT/Op. Count field in this screen, you will get a warning. This tells you that the penalty will not be applied against a flight if value is left unchanged.
