Use of Runway and Clearway | FP&P Flashcards
What is the width of the stop way supposed to be?
The same width as the runway.
Which two lengths combined will equal the accelerate stop-distance?
The runway plus the stopway.
What is the purpose of a clearway, and what is the four ICAO requirements?
The clearway provides a safe area behind the runway for the aircraft to make its initial climb.
- It must be at least 75 metres either side of the runway centre line
- It must be under control of the airport authority
- It must be clear of all obstacles
- It must not be at an elevation higher than that of the runway
Does the clearway include the stopway? Yes or No.
Yes
What symbol is used to indicate a temporary displaced threshold?
Symbol that looks like a little tent(Tents are temporary)
Define “TORA”
Take off run available is the physical length of runway available for the ground run of an aircraft which is taking off.
- A displaced threshold does not reduce TORA
- TORA does not include the stopway length
Define “TORR”
Take off run required is the actual runway length required on a given set of conditions, ie weight, surface wind, temperature and altitude, for an aircraft to become airborne.
Define “TODA”
Take off distance available is the distance available for the aircraft to become airborne and climb to specific height above the surface.
- TODA is the TORA plus the clearway.
- TODA is unaffected by a displaced threshold
Define “TODR”
Take off distance required, is the actual distance required to become airborne on a given set of conditions, ie weight, altitude, temperature, surface wind, for an aircraft to become airborne and achieve a specific height above the ground.
Define “LDA”
Landing distance available, is the runway available from threshold to threshold. Remember, threshold is not necessarily from the beginning of the runway if a displaced threshold is active.
Define the runway slope formula
Difference between threshold elevations divided by runway length multiplied by 100 = slope in percentage,
Define “accelerate stop distance”
This is the distance required to accelerate to V1, experience an engine failure at v1, and stop, using brakes and propeller/thrust reverse with the operative engine.. When calculating the distance, the pilot has to note following:
- Weight, temperature, altitude and surface wind has to considered, since this will obviously affect performance.
- The various conditions will be entered into a performance graph supplied by the aircraft manufacturer.
Define “Accelerate go distance”
This will be the distance required to experience the following, in the following order:
- Accelerate to V1
- Experience an engine failure at V1
- Continue accelerating to Vlof
- Then climb and accelerate in order to achieve climb speed(v2) at 35 ft above the runway.
Atmospheric conditions also need to be taken into consideration when calculating the accelerate go distance.
The length of the runway can be defined as?
The physical length of the runway from the beginning to the end.
The stopway is?
An extension to the end of a take-off runway which may be used to slow down and stop an aircraft in the event of an aborted take-off. Neither the surface, nor the strength is the same as that of the runway.
