Designation:F3064/F3064M15Standard Specification forControl,Operational Characteristics and Installation ofInstruments and Sensors of Propulsion Systems1This standard is issued under the fixed designation F3064/F3064M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers minimum requirements for thecontrol,indication,and operational characteristics of propul-sion systems.It was developed based on propulsion systeminstalled on aeroplanes,but may be applicable to other appli-cations as well.1.2 The applicant for a design approval must seek theindividual guidance to their respective CAA body concerningthe use of this standard as part of a certification plan.Forinformation on which CAA regulatory bodies have acceptedthis standard(in whole or in part)as a means of compliance totheirAeroplaneAirworthiness regulations(Hereinafter referredtoas“theRules”),refertoASTMF44webpage(www.ASTM.org/COMITTEE/F44.htm)which includes CAAwebsite links.1.3 UnitsThe values stated are SI units followed byimperial units in brackets.The values stated in each systemmay not be exact equivalents;therefore,each system shall beused independently of the other.Combining values from thetwo systems may result in non-conformance with the standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2F3060 Terminology for AircraftF3062 Specification for the Installation of Powerplant Sys-temsF3063 Specification for Design and Integration of Fuel/Energy Storage and Delivery System InstallationsF3066 Specification for Powerplant Systems Hazard Mitiga-tionF3116 Specification for Design Loads and Conditions2.2 Other Standards:3US 14 CFR(Code of Federal Regulations)Part 23 Amend-ment 623.Terminology3.1 The following are a selection of relevant terms.SeeTerminology F3060 for more definitions and abbreviations.3.2 Definitions:3.2.1 automatic power reserve(APR)system,nthe auto-matic system used only during takeoff,including all devicesboth mechanical and electrical that sense engine failure,transmit signals,actuate fuel controls or power levers onoperating engines,including power sources,to achieve thescheduled power increase and furnish cockpit information onsystem operation.3.2.2 critical time interval,nperiod starting at V1minusone second and ending at the intersection of the engine andAPR failure flight path line with the minimum performance allengine flight path line.The engine and APR failure flight pathline intersects the one-engine-inoperative flight path line at 122m(400 ft)above the takeoff surface.The engine and APRfailure flight path is based on the airplanes performance andmust have a positive gradient of at least 0.5%at 122 m(400ft)above the takeoff surface.See Fig.1.3.2.3 selected takeoff power,nthe power obtained fromeach initial power setting approved for takeoff.4.Engine Controls4.1 General Requirements:4.1.1 Powerplant controls must be located and arranged perUS 14 CFR 23.777.4.1.2 Each flexible control must be shown to be suitable forthe particular application.1This specification is under the jurisdiction ofASTM Committee F44 on GeneralAviation Aircraft and is the direct responsibility of Subcommittee F44.40 onPowerplant.Current edition approved May 1,2015.Published June 2015.DOI:10.1520/F3064-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from U.S.Government Printing Office Superintendent of Documents,732 N.Capitol St.,NW,Mail Stop:SDE,Washington,DC 20401,http:/www.access.gpo.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.1.3 Each control must be able to maintain any necessaryposition without:4.1.3.1 Constant attention by flight crew members;or4.1.3.2 Tendency to creep due to control loads or vibration.4.1.4 Each control must be able to withstand operating loadswithout failure or excessive deflection that will impede ornegatively affect intended operation.4.1.5 For turbine engine powered airplanes,no single failureor malfunction,or probable combination thereof,in anypowerplant control system may cause the failure of anypowerplant function necessary for safety.4.1.6 The portion of each powerplant control located in theengine compartment that is required to be operated in the eventof fire must be at least fire resistant.4.1.7 Powerpl
