Attention: Mr. C. S. Schneider, Research Assistant
Dear Mr. Schneider:
This is in reply to your letter of April 17th.
It is true that at N.Y. Airspace Subcommittee Meeting #12, we advised you that the Phase II operations would be restricted to weather conditions in which the sky was clear of clouds below 20,000 feet and the visibility at least three miles at all altitudes up to and including 20,000 ft. However, it was indicated that these conditions were subject to concurrence and approval by the Washington Airspace Subcommittee.
In order to expedite final approval of this case, coordination was effected with the Washington Airspace Subcommittee immediately subsequent to our Meeting #12. It was revealed as a result of such coordination that the Washington Committee felt that the ceiling restriction was inadequate in the interests of air safety and required that a cloudless sky condition be specified.
This information was relayed to the members of the N.Y. Airspace Subcommittee and they in turn concurred with this amendment in the interest of air safety. The minutes of New York Meeting #12 were amended accordingly.
Yours very truly,
C. J. Stock
Secretary, N. Y. Airspace Subcommittee
