Discussion

The collection shown above is only a small selection of the wide variety of pictograms used all over the world for the messages Aircraft and Airport.

Using the Production Method Gehringer (1979) explored which mental images or visual stereotypes exist concerning the message Airport. 85 % of the responses showed a plan view of airplane and 5 % an airplane plus a building. While 8 % produced other images that could have been understood, only 2 % of the respondents did not produce anything. Responses show clearly that a plan view of airplane is the dominating visual stereotype.

In the Appropriateness Ranking Tests of the ISO test series 1979/80 regarding more than fifty pictogram variants to indicate the location of an airport (Easterby & Graydon 1981 a), only simplified plan views of airplanes were judged as most appropriate, while side and especially front views of airplanes were placed at the end of the rankings.

The Comprehension Tests in several countries (Easterby & Graydon 1981 b) revealed that all pictogram variants tested were identified as airplanes by about 90 % of the respondents.

In a Japanese study to propose domestically unified graphical symbols based on scientific methods, the pictogram variant labeled as Eco-Mo Foundation reached a comprehension score of 94.6, an almost perfect value (Eco-Mo Foundation, 2001). An when Fiori (2008) examined an map symbol showing a simplified plan view of airplane placed diagonally, 97.2 % of the respondents answered correctly.

These results confirm that a simplified plan view of an airplane - the concept usually followed - is well understood. Displaying additional elements like engines or runway markings does not enhance comprehensibility. The authors of the AIGA study 'Symbol Signs' also mention that 'Details or characteristics that tend to define a specific type of aircraft should be avoided because they cannot remain up to date'.

Recommendations

An aircraft in plan view like the example from AIGA should be used to signify this message, as it is highly comprehensable, not directional when placed like this, and almost impossible to improve concerning distance legibility/visibility (see Eco-Mo Foundation, 2001).
