Claim:
An aircraft display system, comprising: a display device; and a processor in operable communication with the display device, the processor adapted to receive an altimeter setting signal representative of an altimeter setting value and an altimeter value toggle signal and configured to command the display device to: (i) simultaneously render an altimeter and an active altimeter setting field, (ii) at least selectively render a standby altimeter setting field simultaneously with the altimeter and the active altimeter setting field, (iii) in response to receipt of the altimeter setting signal, selectively render the altimeter setting value as either (a) an active altimeter setting value in the active altimeter setting field or (b) as a stored altimeter setting value in the standby altimeter setting field, and (iv) in response to receipt of the altimeter value toggle signal, to selectively command the display device to render the stored altimeter setting value in the active altimeter setting field.
