Lecture 2 - System Planning Flashcards
1
Q
Runway designation
A
- Two digit number: magnetic direction in deg divided by 10.
- In case of parallel runways: L(eft), R(ight), C(enter)
- More than three parallel runways: +/- 1
2
Q
Operational crosswind limits (ICAO)
A
- 20 kts: 1500m < length RW
- 13 kts: 1200m < length RW < 1500m
- 11 kts: length RW < 1200m
3
Q
Cultural differences in airports (areas of difference):
A
- Operations
- Design
- Planning
- Governance
4
Q
Airport master planning involves:
A
- Defining forecast (demand)
- Exam development
- Select a single sequence of development
5
Q
Demand (questions you might want to answer)
A
- Reason of travel (business vs. leisure)
- Origin
- Destination
6
Q
Hub and spoke vs P2P networks
A
- Hub and spoke: less flights to offer al possible connections
- P2P: shorter travel time w/ no transfers
7
Q
Pitfalls of forecasting
A
- Forecasting is an art, not a science: too many assumptions and too many solutions.
- Almost always incorrect, thus inherently risky.
8
Q
Forecasting (basic concept)
A
Estimate past trends and project them forward.
9
Q
Forecasting (things to keep in mind)
A
- Span of data (years)
- Variables (price, income, employment, population, etc.)
- Form of variables (totals, types of variables, etc)
- Equation (linear, logarithmic, exponential)
10
Q
Common variables and their relation (forecasting)
A
- Employment, income, population show exponential behavior.
- Are often related and can be defined as functions of eachother.
11
Q
Uncertainties (forecasting)
A
- Economic recessions
- Oil crises > due to contracts
- Reduction in security (9/11, SARS, Wars, Covid-19)
- Data not always accurate
12
Q
How does growth occur?
A
- Increase in number of routes.
- Increase in capacity on a certain route.
13
Q
How does capacity on a route occur?
A
- Number of flights increases
- Size of the used AC increases
14
Q
Characteristics of demand management
A
- Maintaining efficient operatios at congested airports by reducing total demand and shifting demand from peak to off peak periods
- Use of non capital alternatives
- Mitigation is short to medium term
- Peak period problems
15
Q
Tools to manage demand
A
Administrative
Economic
Hybrid
