2. Airside Components Runways
Taxiways (Significant changes to taxiways occurred recently. See latest FAA Advisory Circulars) *
Taxilanes
Apron

3. Airside Example

4. Airport Types Utility airports Transport airports
Speeds < 120 knots
Transport airports
Speeds >121 knots

5. Design Aircraft Classes
Based on wingspan

TWY 1.2 WS +10
TLN 1.1 WS+10
Behind (object to TWY or TLC CL)
TWY 0.7 WS +10
TLN 0.6 WS+10

10. Apron Area Parking type All around clearance of 0.1 WS+10 Nose in
Angle
Parallel
All around clearance of 0.1 WS+10

11. Example (1/2)

Bounds
RWY
TWY

12. Example (2/2) 1.1 WS + 10 = 129 = separation between taxiways
L+(0.1WS+10)+(WS/2)=230 = distance from taxiway to terminal
L=154
0.1 WS+10=21
0.6 WS+10=75=distance from CL of TW to object
