§3.85 Climb—.

(a) Normal climb condition. The steady rate of climb at sea level shall be at least 300 feet per minute, and the steady angle of climb at least 1:12 for landplanes or 1:15 for seaplanes with: (1) Not more than maximum continuous power on all engines, all be at least 1:30 nding ound loop, porpoise, or water loop, and in such (2) Landing gear fully retracted, (3) Wing flaps in take-off position, (4) Cowl flaps in the position used in cooling tests specified in §§ 3.581-3.596. (b) Climb with inoperative engine. All multiengine airplanes having a stalling speed Vso greater than 70 miles per hour or a maximum weight greater than 6,000 pounds shall have a steady rate of climb of at least 0.02 Vso in feet per minute at an altitude of 5,000 feet with the critical engine inoperative and: (1) The remaining engines operating at not more than maximum continuous power, (2) The inoperative propeller in the minimum drag position, (3) Landing gear retracted, (4) Wing flaps in the most favorable position, (5) Cowl flaps in the position used in cooling tests specified in §§ 3.581-3.596. (c) Balked landing conditions. The steady angle of climb at sea level shall be at least 1:30 with: (1) Take-off power on all engines, (2) Landing gear extended, (3) Wing flaps in landing position. If rapid retraction is possible with safety without loss of altitude and without requiring sudden changes of angle of attack or exceptional skill on the part of the pilot, wing flaps may be retracted.
