Consideraciones sobre ENGINE FIRE ON THE GROUND NNC
Recently changes to engine fire NNC and the new engine fire on the
ground NNC leads pilots to use (EVEN MORE DURING TRAINING) different
criterias on which NNC have to accomplish in case of an engine fire
condition on the ground (master fire warning + engine fire switch
illuminated)
Consulta a Boeing
Example:
During ground operation if we have an engine fire (MASTER FIRE
WARNING + ENGINE FIRE SWITCH ILLUMINATED)
Option 1:
Do the Engine Fire NNC and after item 6 go to the Engine Fire on
the Ground NNC
Option 2:
Accomplish the ENGINE FIRE ON THE GROUND NNC
Which NNC does Boeing prefer as method of operation?
Option 1 or option 2?

The condition statement briefly describes the situation that caused the light,
alert or other indication.

Sin MEMORY ÍTEMS. (Recomendación de la industria)
Se evita el uso de DOS NNC (Engine Fire + Engine Fire on the Ground)
- REQUIERE DEL USO DE MEMORY ÍTEMS, lo cual va en contra del objetivo
del cambio (This change is consistent with the industry effort to reduce
memory items. FOTB 737 21-01)
- Requiere de la lectura de una NNC más, incrementado así la carga
de trabajo y el tiempo de respuesta total, siendo esto contrario al
objetivo del FOTB 737 21-01.
MÉTODO RECOMENDADO
On the ground, Boeing recommends the crew access a
checklist in the quickest way possible. We assume this to be
to go to the Engine Fire on the Ground checklist in the back
cover section. This is a better choice than using the
annunciated ENGINE FIRE checklist. It is easier to find in the
QRH and avoids having to switch between two checklists.
El fabricante recomienda el uso de FIRE ON THE GROUND
NNC.
The new checklist is intended to be used during ground
operations when an engine fire occurs. (FOTB 737 21-01)
Por otro lado, conscientes de que algunos cambios llevan
tiempo en su implementación, dejan como “aceptable”, y
basados en el comportamiento habitual, el uso de la
“annunciated ENGINE FIRE checklist”.
However, in all cases it is acceptable if crew goes to either
checklist. This acknowledges habitual behavior for response
to fire warnings. Both checklists lead to the more
appropriate "on ground" actions.
