På EAA: s AirVenture-flygning på Oshkosh (KOSH) , görs landning och ibland start-verksamhet ofta av prickar som är målade på banan, så att flera operationer (en landning eller en start) görs samtidigt på en enda landningsbanan.
Ett diagram över de prickarna för dem som inte vet vad jag pratar om:
Händer den här typen av banaoperation (det vill säga samtidiga landningar eller startar på en enda banan) någon annanstans eller är detta speciellt för AirVenture?
ICAO definierade förfaranden för Reducerad bananseparation som till viss del tillåter samtidiga operationer på en enda banan. ICAO nämner inte något om färgade prickar, men ICAO-förfarandena öppnas för att göra något liknande det du beskriver.
Följande är från Doc 4444 / PANS-ATM:
7.11.4 For the purpose of reduced runway separation, aircraft shall be classified as follows:
- Category 1 aircraft: single-engine propeller aircraft with a maximum certificated take-off mass of 2 000 kg or less;
- Category 2 aircraft: single-engine propeller aircraft with a maximum certificated take-off mass of more than 2 000 kg but less than 7 000 kg; and twin-engine propeller aircraft with a maximum certificated take-off mass of less than 7 000 kg;
- Category 3 aircraft: all other aircraft.
[...]
7.11.7 Reduced runway separation minima which may be applied at an aerodrome shall be determined for each separate runway. The separation to be applied shall in no case be less than the following minima:
landing aircraft:
- a succeeding landing Category 1 aircraft may cross the runway threshold when the preceding aircraft is a Category 1 or 2 aircraft which either:
- has landed and has passed a point at least 600 m from the threshold of the runway, is in motion and will vacate the runway without backtracking; or
- is airborne and has passed a point at least 600 m from the threshold of the runway;
- a succeeding landing Category 2 aircraft may cross the runway threshold when the preceding aircraft is a Category 1 or 2 aircraft which either:
- has landed and has passed a point at least 1 500 m from the threshold of the runway, is in motion and will vacate the runway without backtracking; or
- is airborne and has passed a point at least 1 500 m from the threshold of the runway;
- a succeeding landing aircraft may cross the runway threshold when a preceding Category 3 aircraft:
- has landed and has passed a point at least 2 400 m from the threshold of the runway, is in motion and will vacate the runway without backtracking; or
- is airborne and has passed a point at least 2 400 m from the threshold of the runway;
departing aircraft:
- a Category 1 aircraft may be cleared for take-off when the preceding departing aircraft is a Category 1 or 2 aircraft which is airborne and has passed a point at least 600 m from the position of the succeeding aircraft;
- a Category 2 aircraft may be cleared for take-off when the preceding departing aircraft is a Category 1 or 2 aircraft which is airborne and has passed a point at least 1 500 m from the position of the succeeding aircraft; and
- an aircraft may be cleared for take-off when a preceding departing Category 3 aircraft is airborne and has passed a point at least 2 400 m from the position of the succeeding aircraft.
(anmärkning: Jag har ändrat formatering något för att bättre passa det här formatet)
Dessa allmänna regler tolkas olika av olika länder, men vissa olika former av minskad bananseparation används på olika platser i världen.
