C.A.A. PILOTS MUST COMPLETE 35 TO 40 HOURS IN AIR BY SUMMER; NO MAKEUP

Some members of the Civil Aeronautics Authority pilot training course may have to stay in Cambridge for several weeks after their last exam is over, according to an announcement from Washington yesterday. A new ruling requires fledglings to finish out their 35 to 40 hours in June or else drop the course altogether ; there will be no make-up next fall.

Three Harvard men have already taken the flight exam and received their private license: two at East Boston and one at Dennison airport. However, because of the unusually bad flying conditions which have prevailed during most of the winter, a large majority is behind in training, and in the middle of June there are certain to be several without the required number of hours.

Advanced Course Planned

An advanced aeronautical course projected for next year has now become a definite probability, according to a statement yesterday by William Bollay, instructor in the ground school, but no details have been learned as to how many students will be admitted or what type of plane will be used.

The present arrangement enables a student to obtain a Class 1 license, which gives him the right to fly planes under 1,300 pounds. A Class 5 license includes anything above 25,000 pounds--the China Clipper, for example. Presumably a student in next year's course would graduate to Class 2 or better.

The exam which this year's candidates for Class 1 must take before June will test emergency maneuvers, sideslips, climbing turns, recovery from stalls and spins, simulated forced landings, and procision landings within 300 feet of an imaginary line on the field.

Landing Drills

Students have been drilled all year on different types of landings and the importance of careful judgement of wind and distance. An error might land the pilot in the situation of the Leverett House Bunny, who, after two hours' solo, misjudged the space he had to land in and saved himself in the nick of time from rolling into the harbor by opening the throttle and taking off again.

Students at the East Boston field have some difficulty landing and taking off because of the extremely heavy traffic--on March 28 a new high of over 1600 takeoffs in a single day was recorded. Dennison, though much less crowded, has a substitute hazard of telephone wires adjacent to the landing space, recalling Will Rogers's definition of an airport: "A small plot of land surrounded by high tension wires."

One of the most favorable results of the nation-wide CAA experiment has been the safety record. Statistics show that the program has been 1100 percent safer than all private flying last year.
