Definition
A Basic Aviation Training Device (BATD) is a ground-based flight training device approved by the FAA that provides a training platform for at least the procedural aspects of flight relating to an integrated ground and flight instrument lesson. A BATD must replicate a generic aircraft and meet the requirements outlined in the current FAA Advisory Circular for ATDs. Time logged in an approved BATD can be credited toward certain pilot certificate and rating requirements, including instrument currency, within limits set by the FAA.
Plain English
A BATD is an FAA-approved desktop or simulator-style training device that lets a pilot practice basic instrument flying procedures on the ground. It doesn't represent a specific aircraft, but it's realistic enough that the FAA allows some training time in it to count toward pilot certificates and instrument currency.
Context Anchor
Seen in flight instructor training, simulator lesson planning, logbook-credit discussions, and FAA guidance on using flight simulation training devices.
Derivation
"Basic" indicates the entry-level tier of approved aviation training devices — below the Advanced ATD (AATD) in capability and credit allowed. The word "basic" here doesn't mean "simple" or "low quality" — it refers specifically to the FAA's approval category.
Why Pilots Care
A BATD lets a pilot log valuable instrument practice time at lower cost than an aircraft or full simulator. Knowing what counts as a BATD (versus an AATD or an unapproved desktop sim) determines whether the time can legally be logged toward currency or a rating.
Intuition Check
“Basic” does not mean “not approved” or “not useful.” Here it means the lower of the FAA’s two main Aviation Training Device categories: Basic and Advanced.
Example Sentence 1
The student logged an hour in the school's BATD practicing holding patterns before flying the same procedure in the airplane.
Example Sentence 2
Before the lesson, the CFI verified that the BATD could be used for the planned navigation exercises.
