WHEELS

5.4.1 General: Aircraft wheels provide the mounting for tires which are designed with proper strength and characteristics to:
• Carry the total weight of the aircraft
• Withstand initial landing impact during touch down
• Offer and withstand high frictional force with the runway pavement
during landing roll
• Avoid aqua-planning (skidding due to water on the runway)



5.4.2 Types and variations:
1. Split wheel-the most popular type.
2. Removable flange type
3. Drop center fixed flange type
The split wheel is used on most aircraft today. Illustrations of wheels used on light civilian type and heavy transport type aircraft are shown to illustrate the similarities and differences.

5.4.3 Split Wheels: Figures 5.7 and 5.8 illustrate the split wheel for light and heavy aircraft respectively.
