Lecture 3 - Airside capacity

Question 1

Classification of flights (4 criteria)

Answer 1

• Aircraft approach
• Airplane design
• Airport reference
• Wing span

Question 2

Approach classification (FAA, speed (kts), 5 classes)

Answer 2

• A: V < 91
• B: 91 < V < 121
• C: 121 < V < 141
• D: 141 < V < 166
• E: 166 < V

Question 3

Airplane design group classification (ICAO/FAA, Wing/Gear span (m))

Answer 3

• A/I: < 15, < 4.5
• B/II: 15-24, 4.5-6
• C/III: 24-36, 6-9
• D/IV: 36-52, 9-14
• E/V: 52-65, 9-14
• F/VI: 65-80, 14-16

Question 4

Airport ref. code (ICAO, ref. field length (m), 4x)

Answer 4

• 1: < 800
• 2: 800-1200
• 3: 1200-1800
• 4: > 1800

Question 5

Maximum throughput capacity

Answer 5

Average number of runway operations (= take-off and landing) that can be performed per hour within ATC rules under the assumption fo continuous demand.

Question 6

Declared capacity (char., 4x)

Answer 6

• Cap per hour used for specifying number of available slots.
• No standard for determination of LOS
• Typically 85-90% of max throughput
• May be adapted to apron or terminal

Question 7

Capacity factors (9x)

Answer 7

• Number of layout runways
• Separation requierments
• Weather (visibility/ceiling)
• Wind (direction/strength)
• Mix of AC
• Mix and sequence of operations (landing/take-off)
• Quality of ATM system (incl. controllers and pilots)
• Runway exit locations
• Noise

Question 8

Main capacity constraint

Answer 8

ATC separation requierments

Question 9

ATC separation requierments

Answer 9

• Divides AC in 3-4 classes (FAA example: H > 255000 lbs, L 41000 < MTOW < 255000, S < 41000)
• Separation specified per combination of classes
