6. ‘WHICH CAME FIRST?’
chicken or an egg? Not that notorious question its aerodrome or aircraft?
Obviously aircraft came first
The aviator first constructed an aeroplane, and then began to search for a suitable ‘airfield’, where he can test it.
The aerodrome parameters had to be selected on the basis of performance and geometrical characteristics of the aircraft.

7. The first aeroplanes were light, with a tail wheel, and the engine power was usually low.
A mowed meadow with good water drainage was sufficient as an aerodrome for those aeroplanes.
the surrounding airspace to be free of obstacles over a relatively wide area.
The main change in the airfield’s physical characteristics was the runway length.
The multiengine aircraft required the length to increase to approximately m.

8. Jet aircraft required further extension of the runway, together with increases in its width and upgrading its strength.
The increasing number of aircraft, and the training of the military pilots required more support facilities at airfields, such as hangars, workshops and barracks.
According to Boeing, air traffic will double by 2020 and new runways will be needed at 60 of the world’s largest airports by 2025.
Boeing predicts that the world aircraft fleet will double by 2025 and estimates a need for approximately new commercial airplanes

9. ICAO REGULATION
Safety is the overriding requirement in aviation. Standardisation is one of the means to achieve it.
In the case of airports, it is standardisation of facilities, ground equipment and procedures.

VAP Visual Aids Panel–visual aids of airports
OCP Obstacle Clearance Panel

10. Cont…
ARCP Aerodrome Reference Code Panel–method for interrelating specifications of airports

ICAO languages (English, French, Spanish or Russian)
STANDARDS contain specifications for some physical characteristics, configuration, materials, performance, personnel or procedures.
Annex 14, include guidelines for aerodrome design, construction, planning and operations.

For an aerodrome used by international civil aviation for non-precision approaches, the elevation and geoid undulation of each threshold, the elevation of the runway end and any significant high and low intermediate points along the runway shall be measured to the accuracy of one-half metre or foot and reported to the aeronautical information services authority.
For precision approach runway, the elevation and geoid undulation of the threshold, the elevation of the runway end and the highest elevation of the touchdown zone shall be measured to the accuracy of one-quarter metre or foot and reported to the aeronautical information services authority.

Navigation Warnings
At both ends of Runway 07/25 its width is twice that of the associated edge lights due to extra pavement at one side. Since runway centre lighting is not installed, pilots should ensure that they are correctly lined up The base of the London TMA overhead is 2,500ft The London Gatwick CTA is 1nm east of the aerodrome On occasions, high performance military aircraft operate to and from Dunsfold Aerodrome

30. Minimum distance between parallel runways
Where parallel non-instrument runways are intended for simultaneous use, the minimum distance between their centre lines shall be:
210 m where the higher code number is 3 or 4;
150 m where the higher code number is 2; and
120 m where the higher code number is 1.

31. NATURE OF RUNWAY SURFACE
The runway length determines the types of aircraft that may use the
aerodrome, their allowable take-off mass and hence the distance they may fly.
The runway surface type must be notified as
bitumen seal;
asphalt;
concrete;
gravel;
grass; or
natural surface.

32. DECLARED DISTANCES
Declared distances are the available operational distances notified to a pilot for take-off, landing or safely aborting a take-off. These distances are used to determine whether the runway is adequate for the proposed landing or take-off or to determine the maximum payload permissible for a landing or take-off.
take off run available (TORA);
take off distance available (TODA);
accelerate-stop distance available (ASDA);
landing distance available (LDA);

33. (TORA) is defined as the length of runway available for the ground run of an aeroplane taking off. This is normally the full length of the runway; neither the SWY nor CWY are involved. (TODA) is defined as the distance available to an aeroplane for completion of its ground run, lift-off and initial climb to 35 ft. This will normally be the full length of the runway plus the length of any CWY (ASDA) is defined as the length of the take-off run available plus the length of any SWY. Any CWY is not involved. ASDA = TORA + SWY

34. (LDA) is defined as the length of runway available for the ground run of a landing aeroplane. The LDA commences at the runway threshold

38. Supplementary take-off distances available (STODA)
Supplementary take-off distances available (STODA). For TODA having an obstacle clear gradient of more than 1.6%, STODA must be provided, except if the STODA is less than 800 m. STODA must be provided for obstacle clear take-off gradients of 1.6%, 1.9%, 2.2%, 2.5%, 3.3% and 5%, up to the gradient associated with TODA. In calculating STODA, care must be taken to ensure that a shielded object does not become critical for the lesser take-off distances
