As found in CAO 40.1.0 APP iii
(which covers Metro 3)
Syllabus: a.b.c. not important to argument
d. Asymmetric flight:The attainment of optimal performance following a simulated engine failure on take-off (at least twice). The speed at which the failure is simulated must be as follows:
(i) in the case of an aeroplane for which the take-off performance is predicted on the establishment of a v1 __ failure of the engine must be simulated at a speed greater than v1;
(ii) not important(unless a Metroii)
e. Night Flying 4 ccts and 1 go around.
*please note that it is an abrieviated quote*
The above tells me that a simulated engine failure 1 knot above v1 is okay, during the day... Definately not at night...
AND as (in the metro v1 = vr) v1 + 1 knot engine cuts are not an issue. (I am able to be educated too)
The original post said EFATO at 90 kias when v1 was around 105 knots... That goes against what is above!!!
That says danger to me...
