The T Instrument Scan Sequence

Instrument scan

The T instrument scan has to always start from the base instrument which is the attitude indicator. Once the attitude is observed, (& understood) the next instrument is chosen.

The order of the scan is not too important as long as the sequence is kept in a T formation.

Attitude ==> Heading ==> Attitude ==> Altimeter ==> Attitude ==> Air Speed Indicator==> Attitude

If in the process of scanning the instruments, an anomally is observed, then scanning of VSI or Turn & Balance indicator might be warranted
