Definition
Written or electronic records made in a pilot's or mechanic's logbook to document flight time, training received, instructor endorsements, aircraft maintenance, or other items required by the regulations. Each entry typically includes the date, a description of what occurred, and the signature and certificate number of the person making the entry when required.
Plain English
Notes written into a pilot's or mechanic's logbook that record what was done, when it happened, and who signed for it. They are the official paper trail that proves training, experience, and required sign-offs.
Context Anchor
You will see this term when an instructor records training, signs off a student for a required step, or verifies that a pilot has completed required experience.
Derivation
From 'log,' originally a wooden float ('log line') thrown overboard on sailing ships to measure speed, with results recorded in a 'log book.' Aviation borrowed the word and the habit: a running written record of what happened, when, and how. The 'entries' are the individual dated notes inside that book.
Why Pilots Care
These entries are legal proof of training and qualifications; incomplete or improper entries can delay certification or result in enforcement action.
Intuition Check
Do not read “logbook entry” as just a casual personal note. In FAA training use, it is a formal record that may prove training, experience, or instructor approval.
Example Sentence 1
