What is the outcome if a pilot requests a speed exceeding the limit without informing of higher minimum speeds required?

When a pilot requests a speed exceeding established limits, the standard protocol is to ensure that safety and operational guidelines are upheld. If the pilot does not indicate that higher minimum speeds are necessary for their aircraft type or operational situation, air traffic control has to prioritize safe separation between aircraft and adherence to established speed limits for that airspace.

Declining the request in such a scenario is a responsible and prudent action taken by the air traffic controller. It ensures compliance with airspace regulations and maintains safety for all aircraft in the vicinity. The emphasis is on maintaining operational standards and safeguarding against possible risks that could arise from exceeding speed limits without proper justification or awareness of the aircraft's performance capabilities.
