Introduction
Air travel is so safe and you probably never have to use any of the advices given to you during the pre-flight safety briefing when you are on-board. But if you ever do need it, flight safety information could
save your life.
3
The Problem
Airline passengers usually take safety for granted when they board an airplane. They tune out the crew's pre-flight announcements or reach for a magazine instead of the cards that show how to open the emergency exit and what to do if the oxygen mask drops down.
Because of this, passengers are needlessly hurt or killed in accidents they could have survived. Avoiding serious injury or surviving an air accident is not just a matter of luck; it's also a matter of being informed and thinking ahead.

Statement of the Hypothesis
There is a significant difference in the level of understanding of pre-flight safety briefing between
frequent fliers, leisure travelers, and aviation professionals
5
Results & Analysis
The one-way ANOVA (one-way simply means that there is only one independent variable) was used and the
following slides present the findings of this study. The main question of this study was:
What are the reasons for some passengers’ lack of attentiveness during pre-flight
safety briefing?

Summary Results: How attentive do you believe you are during the pre-flight
safety briefing?

•Female 65%

•Male 44%
•Female 56%

Analysis
It is observed that the mean (4.4398) of the Aviation Professionals’ group (group 3.00) is higher than the mean (3.7935) of the Frequent Flyers group and the mean (3.5710) of the Leisure Travelers group.
Although the Aviation Professionals’ group mean is higher, this research study investigated if this mean was "significantly" higher.

Table 2. Levene's Test of Equality of Error Variances (a)
Analysis
The Levene's Test was conducted to provide information about the variances of the three different groups of passengers.
The Levene Test's value of .006 is less than the .05 p value that was chosen as the level of significance; therefore, equal variances is not assumed (there is no homogeneity in the variances).

Table 3. Tests of Between-Subjects Effects
Analysis
The important columns of this table are first the "degrees of freedom" (df). The number of df for the (Between) “Groups” is simply the number of groups the researcher is investigating minus one (i.e., 3-1=2). The number of the "Error" (Within Groups) 154 in this case, is the number of total passengers in the three groups (157) minus the total number of groups (3).
The column titled "Sig." referred to the p value. Obviously, in this case the p value is .000; therefore, the null hypothesis was rejected (.000 < .05). Consequently, it was proved in this study that there was a significant difference between the groups. However, since there are more than two groups, it is not obvious where the significant difference lies. Which scores are significantly different from the other?

Table 4. Scheffe Results :Multiple ComparisonsAnalysis
In order to find out the significant differences between the three groups, the above table was observed. After comparing groups 1.00 and 2.00, the researcher observed a p value of .493, so the null hypothesis could not be rejected. The second comparison between groups 1.00 and 3.00 indicated a p value of .003; therefore, the researcher rejected the null hypothesis and stated that there was a "significant" difference between the two groups. Obviously, a third comparison between groups 2.00 and 3.00 indicated a p value of .000; therefore, the researcher rejected the null hypothesis and stated that there was a "significant" difference between these groups.

Why Passengers are Inattentive?
Cabin distraction 41%
Embarrassing 5%
It is the same at all flights 19%
Language barriers 4%
All of the above 31%
12
Ways to Engage
1. Have influential figure endorse safety
2. Make safety “tests” mandatory
3. Minimize the cabin distraction
4. Safety briefing should be demonstrated by different languages
5. Interacting more with the passengers for example of a passenger is sitting in an exit row ask them to volunteer to see if they know the precautions needed if an emergency were to happen
6. Update the videos and make the safety procedures more interesting somehow
13
Conclusion
Based on the above results, this study statistically proved that the Aviation Professionals group has better understanding of the pre-flight safety briefing than the Frequent Flyer and Leisure traveler group of passengers.
Interestingly, the level of understanding of frequent flyers appears to be relatively equal to that of the leisure travelers in that the passengers in these two groups did not have mean scores in the Likert scale questions related to the understanding of the preflight safety briefing that were "significantly" different from each other.
Apparently, the Aviation Professionals’ group is the most educated in
aviation safety and takes the preflight safety briefing more seriously than the other groups of passengers; therefore, airlines should find means in educating and increasing the attention of all passengers before departure safety procedures.
