The answering pennant: Signal Flags and Meanings
The answer pennant belongs to the complete international flag set, without being a letter or a digit. It accompanies the process of communication, confirms different stages of reception and can also represent a decimal sign. Its meaning therefore depends particularly clearly on who shows it, where it stands and in what context it appears.

A procedural mark instead of a single notification
The answer pennant shows five alternating red and white cross fields, beginning and ending with red. While Alfa reports an activity and Oscar an event, the answer pennant fulfills above all a task in the exchange of signals. The English name Code and Answering Pennant reflects several uses. In addition to 26 letter flags, ten pennants and three assistants, it is one of the 40 characters in the ICS set. Another spelling name after the pattern Alfa or Bravo is thus not assigned to it.
The difference is important when learning pictures: recognizing the pennant does not yet fully answer what is being communicated. For him, the procedure is part of the message. The code distinguishes the perception of a flag signal from its understood content. It is precisely this gradation that makes the pennant a vivid example of how communication can require feedback about the message itself.
Seen, Understood and Completely Differentiated
In the flag method described, the response pennant appears at the receiver first in the position at the dip, i.e. approximately halfway up. Fully boosted, close up, he confirms the understood signal. The positions are therefore not decorative variants. They distinguish an initiated reception process from the confirmed communication. NOAA explains the same difference in a learning offer with model flag exchange.
The transmitter can show the response pennant after the last signal individually to indicate the termination. This is a different role than the feedback from the recipient. If the content is unclearly recognizable or not understood, the signal book also provides for distinctions. The basic idea for a knowledge page is therefore: A pennant can carry various procedural statements without needing its own signal image for each of them.
Decimals, code display and race context
Between number pennants, the answer pennant can represent the decimal sign. This use is expressly ignored when determining auxiliary stands: the pennant does not count as an additional numerical position. In addition, the signal book describes a code display by warships in communication with merchant ships. These applications explain the name Codewimpel and show why a single German short definition can only serve as an introduction.
In sailing, the same pennant is often known as the AP and refers to a start postponement according to the race rules. This is an independent sporting significance. A photo of the launch ship can therefore not be explained by the general formulation reception confirmed. Conversely, a start shift is not a universal ICS meaning. The classification shall take into account the role of the showing ship, the rules and, where applicable, other signs shown together.
Details Worth Remembering
Understood is more than seen
The code distinguishes the perception of a sign from the understanding of its meaning. The two positions of the response pennant make this separation visible. This is also a comprehensible example of the difference between reception and successful communication outside the flag customer.
A sign changes its role
As a decimal sign, the same pennant belongs in the middle of a sequence of numbers. He does not confirm a reception there, but structures a number. The position and the context thus explain a function that cannot be read on the isolated flag image.
AP belongs to the sports code at the race
The known use of the regatta as a shift signal must not obscure the process-related ICS tasks. Anyone who labels an image collection should therefore complement the respective context. Thus, both uses can be correctly explained side by side without creating a mixed definition.
