JAR-OPS 1.245 Maximum distance from an
adequate aerodrome for
two-engined aeroplanes
without an ETOPS
Approval
SECTION 1 JAR-OPS 1 Subpart D
JAR-OPS 1.245(a)(1) (continued) JAR-OPS 1.245(b)(2) (continued)
(i) A maximum approved
passenger seating configuration of 20 or
more; or
(ii) A maximum take-off mass of
45 360 kg or more,
the distance flown in 60 minutes at the one engine-
inoperative cruise speed determined in
accordance with subparagraph (b) below;
(b) An operator shall determine a speed for the
calculation of the maximum distance to an adequate
aerodrome for each two-engined aeroplane type or
variant operated, not exceeding VMO, based upon the
true airspeed that the aeroplane can maintain with
one-engine-inoperative under the following
conditions:
(1) International Standard Atmosphere
(ISA);
(2) Level flight:
(B) At the maximum flight
level to which the aeroplane, with one
engine inoperative, can climb, and
maintain, using the gross rate of climb
specified in the AFM, whichever is
less.
(3) Maximum continuous thrust or power
on the remaining operating engine;
(4) An aeroplane mass not less than that
resulting from:
(i) Take-off at sea-level at
maximum take-off mass; and
(ii) All engines climb to the
optimum long range cruise altitude; and
(iii) All engines cruise at the long
range cruise speed at this altitude, until the
time elapsed since take-off is equal to the
applicable threshold prescribed in
subparagraph (a) above.
(c) An operator must ensure that the following
data, specific to each type or variant, is included in
the Operations Manual:
(1) The one-engine-inoperative cruise
speed determined in accordance with
subparagraph (b) above; and
(2) The maximum distance from an
adequate aerodrome determined in accordance
with subparagraphs (a) and (b) above.
Note: The speeds and altitudes (flight levels) specified above
are only intended to be used for establishing the maximum
distance from an adequate aerodrome.

In my opinion the distance is limited to 60 min, one engine out for specified speed for specific aircraft type.
Cheers.
