Various Levels of Data Available | Honeywell EGPWS manual

Various Levels of Data Available

•Low Fidelity Data:

•Slow sample rates (greater than 1 sample per minute)

•Minimal data precision (ie: Latitude, Longitude, altitude, etc)

•Would show long term trending with little inability to show immediate behaviors/signatures.

•Medium Fidelity Data:

•Medium sample rates from 1/sec to 1/minute

•Moderate data precision.

•Would show medium range trending with minimal ability to show immediate behaviors/signatures

•High Fidelity Data:

•High frequency rate of data capture (1Hz or faster)

•High data precision.

•Good indication of immediate behaviors and performance just just

prior to the accident.
