AMC E 500 Functioning - Control of Engines (Turbine Engines for Aeroplanes)

It is normally acceptable that the control of Engines within their limitations may be achieved by manual, as opposed to automatic, means provided that -

(1)The likely rate of change of Engine conditions makes manual control practicable,

(2)Minimum thrust setting parameters for use during all critical flight phases (e.g. take-off or baulked landing) can be predetermined in a manner which will ensure that -

(a)They are easily set-up,

(b)The same instrument is used under all ambient conditions,

(c)They will normally prevent any other limit being exceeded (though normal crew monitoring may be assumed to be adequate for detecting progressive slowly changing excesses which may result from Engine deterioration in service),

(3)The Engine is shown to be safe in the event of inadvertent opening of the throttle to its maximum travel in an emergency situation (see also AMC E 700 paragraph 3).
