1. NIGERIAN AIRSPACE DISTANCES - extract from NAMA Air Navigational Service Billing manual (2002).
- ENROUTE INTERNATIONAL DISTANCES
This relates to the distance flown into or out of the Nigerian Airspace by international flight as captured by Kano Area Control Center, Lagos sub FIR or any other designated airports. The information is on the services rendered to international flights that take off or land in any of the international airports in Nigeria.
The distances are computed through the established route to the first airport of direct contact before linking the other airports through direct measurement. The measurement is in nautical miles and converted to kilometers at the standard rate of 1NM to 1.85km and calculated to the nearest whole number.
Each airport is linked to all the exit/entry points within Nigerian airspace. The formula for computation of such operation is given below.
R=T x D x P
Where R = Charges
T = Unit rate (in US$)
D = Distances flown within the Nigerian airspace reduced by 20km for each take off and another 20kms for each landing and hundreds of kilometers.
P = Weight factor of aircraft = Maximum take off weight in kg (1000/50)
- OVERFLIGHT DISTANCES.
Aircraft overflying Nigerian airspace are bound to use our navigational aids and communication aids and communication facilities. The basis for the computation of the charges is the distance flown between one entry point and the other exit points within Nigerian Airspace.
The various entry/ exit points are identified and their distances calculated which is base on established routes.
Thirty-five entry points were identified and linked to each other. The standard rate of 1NM to 1.852kn is established.
Since Overflyer does not involve land nor take off in any Nigerian airport, the mandatory 20 kilometers for en-route is deducted. The measurement of the distances is in hundreds of kilometers as given in the formula below.
R = T x D x P
Where R = Charges
T = Unit rate in US$
D = Distance flown within Nigerian airspace and measured in hundreds of kilometers.
P = Weight factor of the aircraft = Maximum take off weight in kg
(1000/50)
