Which primary factor is used to determine the minimum runway length during airport planning?
Standard runway width
Design aircraft takeoff distance
Prevailing wind direction
Surrounding terrain obstacles
The key driver in runway length determination is the takeoff performance of the design aircraft, which includes weight, pressure altitude, temperature, and runway conditions. Other factors such as obstacles and wind are considered but the aircraft’s required takeoff distance is primary. This approach aligns with ICAO Annex 14 guidance on runway length. ICAO Annex 14
According to ICAO standards, what is the standard width for a Code E runway?
30 meters
45 meters
60 meters
75 meters
ICAO Annex 14 specifies that a Code E runway, which accommodates large jet aircraft like the Boeing 777, must have a pavement width of 45 meters. This ensures adequate wingtip clearance and ground safety. ICAO Annex 14
What is the primary purpose of a runway end safety area (RESA)?
Provide a flat surface for aircraft overruns
Provide visual guidance for pilots during landing
Aid in runway surface drainage
Hold runway edge lighting fixtures
A RESA is a cleared, graded area beyond the runway end designed to reduce the risk of damage if an aircraft overruns or undershoots the runway. It does not typically include paved lighting or visual aids. The concept is defined in ICAO Annex 14 to enhance safety. ICAO Annex 14 Vol. I
In runway pavement design, what does the PCN represent?
Pavement Condition Number
Pavement Classification Number
Pavement Coefficient Nominal
Pavement CBR Number
The Pavement Classification Number (PCN) is a standardized indicator of pavement strength used internationally to inform which aircraft can operate on the pavement without risk of structural damage. The ICAO PCN system pairs with the Aircraft Classification Number (ACN). FAA AC 150/5335-5D
What is the recommended minimum runway surface friction coefficient to ensure safe braking under wet conditions?
0.20
0.35
0.70
1.00
Runway friction testing aims for a mu value of around 0.35 or higher under wet conditions to maintain safe braking performance for most transport aircraft. Values lower than this can compromise stopping distance. FAA Pavement Friction
What is the maximum recommended longitudinal slope for a runway according to ICAO Annex 14?
0.3%
1.0%
1.5%
2.0%
ICAO Annex 14 limits the longitudinal (surface) gradient of a runway to a maximum of 1.5% to ensure safe acceleration and deceleration of aircraft. Steeper grades can negatively impact performance and safety. ICAO Annex 14
Which factor is most critical when determining the optimal runway orientation at a new airport site?
Prevailing wind directions (wind rose)
Subsurface soil type
Availability of electrical power
Nearest navigational aid location
Runway orientation is selected primarily to align with prevailing winds, minimizing crosswind components and enhancing safety. Wind roses are analyzed for this purpose. Other factors are secondary. FAA Wind Analysis
At a high-altitude airport, which environmental factor most significantly increases the required runway length?
Lower air density due to altitude
Higher ambient humidity
Increased solar radiation
Reduced crosswind frequency
High altitude reduces air density, which degrades aircraft engine thrust and aerodynamic lift. This results in longer takeoff runs. ICAO performance charts account for pressure altitude. ICAO Aircraft Performance Manual
What is the primary function of a runway blast pad?
Mark high-tension cable routes
Provide a smooth transition for landing aircraft
Protect paved areas from jet blast erosion
Assist in runway visual range measurement
Blast pads are constructed at runway ends to protect adjacent pavement and soil from high-pressure jet blast during takeoff. They are not intended for normal aircraft operations. FAA AC 150/5300-13B
How wide is the runway strip (graded area) around a Code 4 runway as specified by ICAO?
120 meters
150 meters
300 meters
500 meters
According to ICAO Annex 14, a Code 4 runway requires a runway strip width of 150 meters (75 meters each side of the centerline). This area ensures obstacle clearance for aircraft operations. ICAO Annex 14
Which method is commonly used to design flexible runway pavement layers based on aircraft loading?
Equivalent Single Wheel Load (ESWL) method
Finite Element Analysis method
Axle Fatigue Factor method
California Bearing Ratio (CBR) index only
The ESWL method converts multiple wheel and axle loads into a single wheel load equivalent, simplifying pavement design. It is widely adopted in both ICAO and FAA flexible pavement design guidelines. FAA AC 150/5320-6
During runway drainage design, what minimum transverse slope is typically used to ensure adequate surface runoff?
0.5%
1.0%
1.5%
2.5%
A transverse slope of around 1.5% is generally specified for runway pavements to promote water runoff without compromising aircraft handling. This balances drainage efficiency and safe operations. FAA Pavement Design
What is the typical frost penetration depth considered in runway pavement design for cold regions?
0.1 meter
0.5 meter
1.0 meter
2.0 meters
In cold regions, pavements must account for frost heave; typical design assumes about 0.5 meter of frost penetration. Local climate data refines this value. FHWA Frost Design
For runways subjected to heavy jet operations, which material property is most critical in pavement selection?
Compressive strength
Resilience modulus
Fatigue resistance
Thermal conductivity
Repeated heavy loads from jet aircraft induce fatigue damage in pavements. Thus, selecting materials with high fatigue resistance is essential to ensure long-term durability and reduced maintenance. FAA Pavement Fatigue
In advanced runway longitudinal profile design, which formula is commonly used to compute the length L of a vertical curve given an algebraic grade change A and a constant K?
L = K × A
L = K ÷ A
L = A ÷ K
L = K + A²
The length of a vertical curve for aircraft operations is typically calculated using L = K × A, where A is the algebraic difference in slopes and K is a constant based on design speed. This ensures smooth transitions. FAA AC 150/5300-13B

Cheat Sheet

  1. Pavement Thickness & ESWL Calculation -

    When an engineer is designing the runway for an airport, converting different gear configurations to an Equivalent Single Wheel Load (ESWL) is key. Use the FAA AC 150/5320-6 formula ESWL = P·(L/B)^0.4, where P is wheel load, L is tire footprint length, and B is width. Practicing runway design MCQs on ESWL conversion helps cement this formula.

  2. Subgrade Strength & CBR Testing -

    Determining the California Bearing Ratio (CBR) of the subgrade ensures your pavement layers will support aircraft loads. Aim for a lab-tested CBR ≥ 5% for rigid pavements per AASHTO guidelines; a handy mnemonic is "C-B-R: Concrete's Backbone Rating." Reviewing airport engineering practice test questions on CBR interpretation builds confidence.

  3. Runway Length Determination -

    Calculating takeoff and landing distances involves adjusting standard performance data for elevation, temperature, and slope: L = L0·(1 + 0.007·H), where H is elevation in hundreds of feet. For example, a 1,500 m sea-level runway becomes about 1,605 m at 1,500 ft elevation. Challenging yourself with an airport runway design quiz on these corrections is an effective study tool.

  4. Pavement Types: Rigid vs. Flexible -

    Rigid (concrete) pavements distribute loads over a wide area via high stiffness, while flexible (asphalt) pavements rely on layered strength and compaction. Remember: "Rigid is solid, Flexible rolls." Comparing pros and cons in runway design MCQs reinforces your material selection skills.

  5. Runway Safety Areas & Object Free Zones -

    ICAO and FAA require a Runway Safety Area (RSA) of 150 m wide and 300 m beyond each end to protect overruns. Incorporate these clearances early in layout plans to meet compliance. Testing yourself with airport engineering quiz scenarios on RSAs ensures you won't miss critical safety dimensions.
