With machine fully loaded and at an altitude of 2,000 meters the maximum speed must not be less than 260 kilometers per hour.

(h) Minimum velocity:

Minimum velocity must not exceed 90 kilometers per hour at 500 meters with entire crew, fuel sufficient for one hour's flight and without bombs.

(i) Climb:

Three thousand meters is not over 15 minutes, with machine fully loaded.

(j) Coefficient of safety in the static test:

The coefficient of safety in the static test with respect to conditions of a full normal load, must not be inferior to ll.  In every case this test must fulfill the rules prescribed by the Institute of Experimental Aeronautics for carrying out the static tests, due account being taken of the characteristics of the machine.

(k) Preference conditions:

Under the same conditions, preference will be given to multi-engined machines.  Having the engines fitted with mufflers will be a preference condition also.
