Taxiing a retractable gear aircraft in slush, snow, or ice-covered taxiways presents several challenges that can severely affect safety and performance. These conditions create a risk for losing control during taxi, as the wheels may not have adequate traction, potentially leading to skidding or sliding. Additionally, ice and snow could conceal surface irregularities, making it difficult for the pilot to maintain proper control and awareness of the aircraft's position.

Furthermore, retractable gear aircraft often have a specific ground handling procedure, and adverse conditions can complicate these procedures, increasing the risk of mechanical extensions or retractions of the gear if not done properly. Under such conditions, the aircraft is more susceptible to damage from bumps or unseen obstacles.

In contrast, dry pavement provides optimal traction and control, while rainy weather, although it can present challenges such as reduced visibility, is generally manageable with appropriate pilot techniques. Sunny weather presents no inherent risks related to surface conditions for taxiing. Thus, slush, snow, or ice-covered taxiways are indeed the most problematic for taxiing safely in a retractable gear aircraft.
