The topics covered within this specification are:(4.1) Low-Speed Flight Characteristics Score, (4.2) Stall Characteristics, (4.3) Stall Warning, (4.4) Departure Characteristics:Single Engine, (4.5) Departure Characteristics: Multiengine, (4.6) Spinning, and (4.7) Safety-Enhancing Features.1.2

6、 The term “aeroplane” is utilized in this specification as it was originally conceived for normal category fixed wing aircraftwith a maximum certificated weight of 8618 kg 19 000 lb or less and a passenger seating configuration up to 19 as defined inthe Rules. However, these standards may be more br

7、oadly applicable and their usage should not be unnecessarily limited.1.2 The applicant An applicant intending to propose this information as Means of Compliance for a design approval shallmustseek the individual guidance tofrom their respective civil aviation authority (CAA) body concerning the use

34、light, turning flight,and accelerated turning flight.4.2.1 Wings-Level Stall: Compliance with these requirements shall be shown under the following conditions. An example tableof relevant permutations of these conditions are given in Appendix X1.4.1.1.1 Primary Flight Control Behavior:(1) For single

35、 engine low-speed Level 1 aeroplanes with VS0 45 knots that have interconnected lateral and directionalcontrols, it shall be possible to produce and correct roll by unreversed use of the lateral control without producing excessive yaw,up to the time the aeroplane stalls.(2) For all other Level 1 aer

36、oplanes, and all Level 2, 3, and 4 aeroplanes, it shall be possible to produce and correct roll byunreversed use of the lateral control and to produce and correct yaw by unreversed use of the directional control up to the timethe aeroplane stalls.NOTE 2The differentiation in conditions between Level

37、 1 and Level 2, Low-Speed, Single Engine aeroplanes, vs. all others, is based off guidancegiven in AC 23-15A (see 2.2).4.1.1.2 The wings-level stall characteristics shall be demonstrated in flight as follows. Starting from a speed at least 18.5 km/h10 knots above the stall speed, the longitudinal co

38、ntrol shall be pulled back so that the rate of speed reduction will not exceed1.9 (km/h)/s 1 knot/s until a stall is produced, as shown by either:(1) An uncontrollable downward pitching motion of the aeroplane,(2) Adownward pitching motion of the aeroplane that results from the activation of a stall

39、 avoidance device (for example, stickpusher activation), or(3) The longitudinal control reaching the stop.(1) Wing FlapsAs follows, based on the type of aeroplane:(a) For Level 1 and Level 2, low-speed, single-engine aeroplanes: Retracted, fully extended, and in the maximum approvedextension for the

40、 takeoff configuration,(b) For all other aeroplanes: Retracted, fully extended, and each intermediate normal operating position as appropriate for thephase of flight;(2) Landing GearAs follows, based on the type of aeroplane:(a) For Level 1 and Level 2, low-speed, single-engine aeroplanes: Retracted

41、 for the configuration in which the wing flaps areretracted, and extended for all other wing flap extensions,(b) For all other aeroplanes: Retracted and extended as appropriate for the phase of flight and altitude;(3) Cowl FlapsAs follows, based on the type of aeroplane:(a) For Level 1 and Level 2,

42、low-speed, single-engine aeroplanes: Open for the configuration in which the wing flaps are inthe maximum approved extension for the takeoff configuration, otherwise closed,(b) For all other aeroplanes: Appropriate to configuration;(4) Spoilers/Speed BrakesRetracted and extended unless they have no

43、measurable effect at low speeds, or in their appropriateposition if they are automatically actuated as part of normal operations;(5) Power/thrust idle;(6) Power/Thrust OnDepending on engine type, one of the following applies:(a) For Reciprocating Engine Powered AeroplanesSeventy-five percent of maxi

44、mum continuous power. However, if thispower setting results in nose-high attitudes exceeding 30, the test may be carried out with the power required for level flight inthe landing configuration at maximum landing weight and a speed of 1.4 VS0, except that the power may not be less than 50 %of maximu

45、m continuous power; or(b) For Turbine Engine Powered AeroplanesAt maximum engine thrust, except that it need not exceed the thrust necessaryto maintain level flight at 1.5 VS1 (where VS1 corresponds to the stalling speed with flaps in the approach position, the landing gearretracted, and maximum lan

47、n for the idle condition.(9) WeightWith the aeroplane at the most adverse operational weight(s) for the particular stall characteristics test beingconducted, as determined by simple analysis from the applicant; and(10) CGWith the aeroplane at the most adverse center of gravity location(s) (along the

48、 longitudinal, lateral, and directionalaxes) for the particular stall characteristics test being conducted, as determined by simple analysis from the applicant.4.1.1.3 Normal use of longitudinal control for recovery is allowed after the downward pitching motion from 4.1.1.2(1) or4.1.1.2(2) has unmis
