UNITED NATIONS PALESTINE COMMISSION
Communication Received from United Kingdom
Delegation Regarding Equipment at Lydda
Airport




The following communication, regarding equipment at Lydda Airport, has been received from Mr. Fletcher-Cooke of the United Kingdom Delegation.







UNITED KINGDOM DELEGATION TO THE UNITED NATIONS
Empire State Building
New York 1, N.Y.


CONFIDENTIAL
20th April, 1948.

My Dear Bunche,

May I refer to your letter of the 25th March regarding certain equipment at Lydda Airport.

2. In the second paragraph of your letter, you stated that the Commission would welcome the technical assistance of the Government of Palestine in determining what equipment will be required.

3. I now enclose a schedule of items which, in the opinion of the Director of Civil Aviation, Palestine, require replacement or supply.

4. The Director of Civil Aviation considers that the items shown under the heading “(a) Radio Aids to Navigation” should be given priority over the its shown under the heading “(e) Point to Point and Air/Ground/Air Channels”, as they more directly affect the safety of aircraft. It will be observed that items are included in this schedule which already exist at Lydda but it is considered desirable to state the condition and usefulness of these items, even where they do not require replacement.


Yours sincerely

(signed) J. FLETCHER-COOKE

Principal Secretary to the United Nations

(a) RADIO AIDS TO NAVIGATION

The following information has been related to PICAO Document 2553 COT 26 dated. January 1947

Remarks
(i) N/F Radio Beacon (2KW)Installed and functioning efficiently. No requirement for new beacon provided spares readily available when required.
(ii) HF D/F Station (Short Range)A completely new installation is required. The present equipment will suffice for a little longer.
(iii) VHF D/FThe present VHF D/F can be used in emergency only. A new up-to-date installation is required, such as the cathode ray type.
(iv) EUREKA Responder BeaconThe present beacon is completely worn out. This is an immediate requirement.
(v) BABS M.K. IIThis should be retained until PICAO recommendations lay down definite policy, equipment is serviceable; but become of recent theft no spares are available.
(vi) Instrument Landing SystemNone available at the Airport. Although the weather is almost constantly good, there are times when some system of blind approach is necessary, especially as the Ramallah hills are high, and low approach is dangerous. Also power failures are frequent in wet weather and flarepaths become unreliable.

VHF aquisignal localiser and. glide path equipment is required and PICAO state that it should be installed as soon as possible. If the above equipment is not available, a type SCS51 equipment complete shoed be made available.
