Principal interactions between the environment and the aircraft in Figure 3.4
1. Landing environment interaction-Landing environment is an external interface. It is made
up of shock, vibration and ILS Beacon. This involves the housing system that is designed
to give compatibility to the constraints that the landing environment may expose the
aircraft to (Kossiakof et al., 2011). The installers must provide a mechanical mounting to
ensure the system is not subjected extreme shock and vibration.
2. Support Environment interaction- This is an external interface. It is comprised of power
and fuel. Support systems are part of aircraft’s infrastructure which it depends on while
functioning or carrying its mission. This is what makes the aircraft operate well. The air
control traffic system is also part of the support system (Kossiakof et al., 2011). The
design of the support system represented in the aircraft is a standard interface that helps
the aircraft’s system to function harmoniously.
3. Flight Environment interaction—Flight environment is an external interface. It consists
of the winds, turbulence, flight commands and beacon interrogation. These external
entities are either natural or human-made (Kossiakof et al., 2011). Weather is a threat
which can expose the system to risks. For example, the water environment can be very
corrosive that can affect the system. Threats to the system are supposed to be identified
for them to be considered while designing the aircraft.
4. Maintenance environment interaction- Maintenance environment is an external interface.
It ensures the readiness of the system to operate (Kossiakof et al., 2011). The system
needs to be designed in a manner that provides access to testing, monitoring and repairing
requirements which should be included in the construction of the aircraft. It is therefore
essential to explicitly recognize the maintenance environment.
a. Functions performed:
Water inlet control valve-control amount of water required in the washing
Water pump- circulates water to the machine and also re-circulates.
Tub- inner and outer tubs- inner tub washes, rinses and dries clothes. Have holes
to drain water. Outer tub in thinner than the inner tub.
Rotating disc or agitator- is inside the tube. It performs the actual cleaning of the
The motor of the washing machine- with agitator produces motion. Timer- Sets
the washing time for clothes. It is automatic
Printed Circuit board (PCB)- made of electronic components. It calculates the
total weight of the clothes.
Drain pipe-removes dirty water from the washing machine
b. Physical components (Kossiakof et al., 2011).
Solenoid valve- the point of water entry in the machine- electromechanical
Rotating disc-electromechanical-cleans the clothes
Motor-initiates electromechanical motion that generates energy
PCB-calculate weight to help in the normal functioning.
Tub- inner and outer- inputs electrical pressure through using a transducer

The adolescents who are faced with diabetes have a high number of infections in the
general state. There are no clear means the healthcare system deals with these kinds of diseases
because they are termed as hereditary. Also, the treatment of diabetes among adolescents has
dramatically impacted both positively and negatively the social, economic state of the nation.
These have to lead to the reduced amount of the income that is earned and the way various
groups relate to each other. The population suffering from the disease is standing at around 23%
which is a significant number of people for the state to manage. Most of the adolescents that
develop the diabetes complications are at the same time infected with another kind of diseases
because of their immunity that is weak thus probable to a variety of conditions. The adolescents
on the other hand they require, improved management and evaluation. This makes it a high
burden for the American state to handle them, significantly (Engelgau et al. 2004). It will have to
spend almost half of their revenue in the treatment and prevention of the diseases.
Diabetes has greatly impacted the state both socially and economically. That is because;
it has demarcated or drawn a boundary between the old and the adolescents. This means there
will be great instances of discrimination during the time services are offered, because they may
favour either way. The amount of state money spent will as well have been used in the
development of some other state projects (Scott, at al. 2007). The generation that is ailing could
have been used to help in generating the income of the state, but instead, it is consuming what
has already been made. This means that the economy will drug behind due to the reduced
workforce to render the general services.
PUBLIC HEALTH COMMUNICATION PLAN
The parents as the target audience will help in disseminating the information to the
relevant groups. The adolescents who are suffering will be guided by their parents that are why
they are the best people to be used as the target population. Parents were singled out because
they can instil discipline in their children and force them to force the health message that has
been communicated to them. On the other hand, the oarent6s ...
