3.4 AMPLIFIED EMERGENCY PROCEDURES
This section is provided to supply the pilot with additional information concerning emergency
procedures in general. Elaboration of the procedures specified in the EMERGENCY
PROCEDURES CHECK LISTS as well as the inclusion of some more generalised emergency
procedures that can be better covered by a general descriptive procedure rather than a formal
check list are included in this section. This will give the pilot a more complete understanding of
these procedures.
3.4.1 Fuel Gauges / Low Level warning Light (where equipped)
The J160-C may be fitted with electronic fuel gauges on the instrument panel. In addition, the
sender units which drive these gauges are visible in the wing root area and incorporate an
analogue needle showing fuel level. While the gauges on the instrument panel are designed so
that only extended changes in fuel level are shown, the sender units in the tank show the current
level directly and so will change in flight as the fuel sloshes in the tank. These senders can be
used as a direct confirmation of the level indicated on the gauges. Note that due to the shape of
the wing tank the gauges will read full from when the tanks are full (67 Litres) until the level falls
below approximately 50 litres.
The optional low fuel level warning light will illuminate when around 3 litres of fuel remain in the
header tank. This will allow the crew around 10 minutes (at cruise power consumption) to attempt
to fix the problem with the fuel feed (such as flying out of balance, with the wing containing more
fuel higher to encourage fuel flow from it into the header tank) or to locate a suitable place for a
precautionary landing. While false indications are possible from this system they are unlikely, and
unless the pilot is confident that he has sufficient fuel
and that it is reaching the header tank, he
should immediately reduce fuel consumption and seek a suitable place to carry out a
precautionary landing. Note that this is a separate system from the fuel pressure warning light.
3.4.2 Engine Failure
If an engine failure occurs during the take-off run, the most important action is to stop the aircraft
on the remaining runway. The extra items in the checklist will provide additional safety after an
engine failure on take-off.
If the engine fails shortly after lift off the initial response must be prompt lowering of the nose in
order to maintain safe airspeed. In most cases, the landing should be executed straight ahead
with only small changes in direction to avoid obstructions. After an engine failure on take-off,
altitude and airspeed are seldom sufficient to execute a 180
°
gliding turn to return to the runway of
departure. The checklist procedures assume that adequate time exists to secure the fuel and
ignition systems prior to touch down.
After an engine failure in flight, the best glide speed should be established as quickly as possible.
While gliding toward a suitable landing area, an effort should be made to identify the cause of the
failure. If time permits, an engine restart should be attempted. If the engine cannot be restarted a
forced landing must be executed.
3.4.3 Forced Landings
If all attempts to restart the engine fail and a forced landing is imminent, a suitable landing area
should be selected and the EMERGENCY LANDING WITHOUT ENGINE POWER checklist
should be completed if at all possible.
