(I am not a proffessional pilot yet so I will post this in this subforum)
The FAA Aeronautical Information Manual (AIM) describes two types of threshold markings but fails to inform when the different types will be used. The "configuration A" being 8 longitudal pianokeys and "config B" being longitudal pianokeys and the number of pianokeys being a code for the RWY-width...
How can I tell the difference between a config A (8 pianokeys) and config B on a 100ft wide RWY which also has 8 pianokeys?
When do they use config A vs config B?
