Mr. Archie W. League (2) The facts in this case show that even a small lateral deviation from the specified departure course, if not detected immediately by the pilot or controller could result in a disastrous accident within a matter of seconds. Further, in the FTL accident the aircraft was climbing at the approximate 250' per mile minimum rate of climb specified in the current SID's (Gap 5 and Sutro 1). This fact emphasizes the critical lateral limits involved.

To enhance the safety of such operations, it is recommended that the SFO departure controller be provided with an additional radar display, to be operated on a suggested 6-mile range setting. This will provide the controller with the capability for more effective radar monitoring service to departing aircraft at this location which has a terrain-critical departure route.

In your reply of August 3, 1965, to our letter of July 23, 1965, it was indicated that you did not deem it appropriate to prominently display on pertinent aeronautical charts, "areas wherein the provision of radar services may have limitation." Our previously suggested wording for the box at the top of the sample chart perhaps was misleading to you as to our intent.

The note might also be written in the negative, as follows:

"Runway 28 Departures --- Radar vectoring service not available below 1500 feet m.s.l."

In view of the foregoing, we respectfully request that this matter be reconsidered.

In addition to the personnel mentioned heretofore, this matter has been discussed with Messrs. Bernard Curtis and Edward Krupinski. Should you desire additional information, please contact our Investigation Division.
