Section 3 – Emergency procedures
INTRODUCTION

NTRODUCTION
Section 3 includes checklists and detailed procedures for coping with various
types of emergency conditions that could arise after a system failure.
The procedures affected from installation of the Special Mission Platform are the
following:

Single alternator failure / overvoltage

Both alternators failure

Both alternators overvoltage

Engine securing

Total electrical failure

Inflight engine restart

Engine failure during takeoff run

Engine failure during climb

Engine failure in flight

Engine fire on the ground

Engine fire during takeoff run

Engine fire in flight

Electrical smoke in cabin on the ground

Electrical smoke in cabin during flight
The main difference regarding aircraft systems, compared with the basic AFM, is
the presence of the Power supply from built-in generators, Alternators with 70A
and Converter Box. The powering and disconnection of converter box is very
simple and, in most of abnormal cases, is automatically managed by relays and
safety provisions.
The converter box (following described in Section 7) is managed by the pilot only
via two switches, located in the bottom LH side of pilot seat on a single panel
provided by: two switches, two breakers and two indicating lamps.
Only when pilot selects BOTH switches ON (right and left AUX) and both alter-
nators are operative the system allows a surplus of power generated by the en-
gines and alternators to flow into 4x converters and, then, into mission equipment,
when installed.
The health status of converters inside the box (located into the baggage compart-
ment) is monitored by mission operator, via 4x failure indicating lamps. Follow-
ing the key concepts when managing converter boxes:
1. Mission Power Switches: they enable the converter box ONLY when
BOTH are set to ON;
2. Converter box power: enabled only if both LH and RH main alternators
are generating power;
3. Converter box: automatically switches OFF in case LH or RH main alter-
nators is faulty / not generating;
4. Converter box: automatically switches OFF in case LH or RH mission
switch is set to OFF;
