Plain English Meaning
Doing the same thing over and over in one session before switching to something else. Think of practicing only landings for an hour, then only stalls for an hour, rather than mixing them.
Full Definition
A practice method in which a learner repeats the same skill or task many times in a row before moving on to a different skill. The repetition is grouped together in a single, uninterrupted block.
Context Anchor
Seen in flight instruction discussions about how to structure practice sessions, such as repeating several steep turns before moving on to slow flight or stalls.
Derivation
‘Blocked’ here means grouped together in a single chunk or block of time, as opposed to spread out or mixed with other tasks. The word highlights that all the repetitions sit in one continuous block.
