What is indicated if the min flap retraction speed is not displayed during flight?

The indication that the min flap retraction speed is not displayed during flight suggests that it is not pertinent to the current phase of flight. This situation commonly occurs when the aircraft is either not configured for flap retraction or is operating within a flight envelope where flap retraction speeds do not need to be displayed, such as during takeoff or when flaps are already retracted.

In various phases of flight, particularly during landing or when flaps are being deployed or have just been deployed, the aircraft may not display this speed if it does not apply to the current configuration or conditions. For example, if the aircraft is in a clean configuration (with the flaps retracted), the indication may not be relevant, hence the absence of a displayed speed.

Other options relate to specific scenarios that would not universally apply. For example, the presence of fully extended flaps, an incorrect configuration, or being in landing configuration would imply conditions where some indication might still be relevant. However, if those specific conditions do not exist, the absence of a display aligns with the conclusion that the information is simply not applicable at that time.
