Description of Fuel Dumping Aircraft Configuration 

We estimate that this will take 1 minute to complete.

2       Detailed Explanation 

ETP Fuel Dump Configuration

Fuel dumping is used in ETP engine failure situations. If due to an engine failure an aircraft type is unable to maintain a safe altitude that meets drift down requirements, N-FP will calculate the necessary amount of fuel to be dumped in order to maintain a safe altitude (MORA). A field can be added to the flight plan fuel block that provides the amount of fuel to be dumped in an ETP engine out scenario.

In order to implement fuel dumping you need to contact NAVBLUE performance engineering to enter the necessary performance data.

The following steps will show how to enable fuel dumping for a particular aircraft type.
