Civil Aviation Operational Point to Point Facilities -

1. GENERAL
1.1. A British Ministry of Civil Aviation Survey party has recently surveyed the
route facilities extant in the area mentioned above. It was clearly apparent
tl^t a minimum reinforcement of the main staging post and terminal point to point
fi ilities was necessary. This was due, in the main, to the time factor
involved in implementing of the Cairo P.I.C.A.O. Civil Aviation recommendations
and to the very rather limited Met and operational control facilities available.
1.During the visit to Dharhan, a request was received for direct communication
Karachi/Dharhan on behalf of American operators.
1 O. On arrival at Karachi, the Tels. Adviser to the M.C.A. Survey Mission and the
Regional Signals Officer, B.O.A.C. approached the D.G.C.a's Department local
official for his views on the point to point requirements.
1.4-. It was early revealed that in addition to the British operator's’ request
there were additional requests from American operators.
1.f. The D.G.C.A’s Deptt: India had already formulated an outline plan for just
such point to point organisation working from India westwards.
1.6. there exists, at the moment, long range Civil Aviation net-work operating on
schedule basis linking many of the relevant locations and a short range interstage
net-work linking all intermediary points.
1./. The frequencies employed are dangerously over-loaded from an operation view
point and the creation of an additional main staging post net-work appeared the
only solution.
2. ACTION INITIATED
2.1. After discussion, agreement was reached to signal Air Headquarters of the
D.G.C.A s department in Delhi for agreement in principle for the opening of an
independent operational Civil Aviation Point to Point medium stage channel from
Karachi linking Basra, Lydda, Dharhan and/or Bahrein Cairo and Ankara. The
suggested frequencies are 10955, 8140, 3670 Kcs. operating on continuous basis
with scheduied. times for normal traffic. The existing long range network on
1o05, 12012, 9510 and 4145 Kcs. to be retained for terminal to terminal working
such as Cairo, Karachi, Calcutta, Colombo, Rangoon, Singapore, Hongkong, with
variations as operational commitments decide.
2.2. Advice has been received that D.G.C.AJs Department Delhi agrees in principle
and the discussions will be pursued for immediate implementation within a few
days at Delhi.
2 . 3 . A signal indicating the decisions already reached will be prepared for trans
mission to all relevant authorities.
3. OTHER OPERATORS’ REQUIREMENTS
3*1. Coincidental v/ith the above negotiations, representatives of P.A.A. and T.W.A.
arrived in Karachi to discuss their requirements. It was indeed fortunate that
such an opportunity arose since it was clearly apparent that the operational need
° r , facilities was common to all operators concerned and it presented to the
a.G.C.A s Department^ an opportunity to implement an International Civil Aviation
Point to Point facility on a common basis. The desirability of provision of these
facilities in this manner affords an immediate opportunity of implementation of
agreed P.I.C.A.0. International policy.
4. CONCLUSIONS
. It is f therefore, desired that the representatives of Operators concerned
review the negotiations and plans outlined above and indicate their concurrence
The details of the operational procedure to be adopted, the assessment of average
traffic loads and the probable efficiency of the freauencies chosen to be left to
the responsible technicians.
