Which type of data does the ESD not display in the cockpit?

The Engine Systems Display (ESD) is primarily focused on providing information relevant to the engine and propulsion systems of the aircraft. The types of data typically displayed on the ESD include parameters related to the hydraulic system, oil system, and electrical system, which are critical for monitoring the functioning of the aircraft's propulsion and power management.

The "outside environmental" data primarily relates to external conditions such as air temperature, pressure, and humidity, which are not part of the ESD's direct focus. Instead, this type of data is usually monitored and displayed by different systems or panels that cater to environmental conditions, rather than engine-related parameters. Hence, the ESD does not display this kind of environmental data in the cockpit, confirming why this answer is considered accurate.
