LIMITATIONS
EMB-145 A1 FAA
5) May be exceeded during starts if oil temperature is below
21°C. The engine must remain at IDLE until the oil pressure
is less than 95 psi (110 psi for airplanes Post-Mod. SB 145-
73-0022 or equipped with an equivalent modification factory
incorporated).
6) Operation in oil pressure amber range between 96 and
115 psi is permitted in all operational modes and time limited
to 5 minutes, or between 116 and 155 psi in all operational
modes time limited to 2 minutes. Total time above 95 psi
may not exceed 5 minutes.
7) For airplanes Post-Mod. SB 145-73-0022 or equipped with
an equivalent modification factory incorporated the upper
limit of the oil pressure green band is 110 psi. Operation in
oil pressure amber range is permitted between 111 and
115 psi in all operational modes time limited to 5 minutes, or
between 116 and 155 psi in all operational modes time
limited to 2 minutes. Total time above 110 psi may not
exceed 5 minutes.
8) While this is an abnormal condition, operation between
50 psi and 34 psi is permitted during takeoff and go-around
phases.
9) Minimum oil temperature for starting is -40°C for lubrication
oil specified by MIL-L-23699D and -54°C for lubrication oil
specified by MIL-L-7808K.
10)Vibration in the amber range below 2.5 IPS is time limited to
5 minutes during the takeoff or go-around phases or
10 seconds during the remainder flight phases. High
vibration indicates a malfunction which may worsen and
increase vibration severity. Therefore, continuous engine
operation with vibration in the amber range is not
recommended. According to engine vibration limits, the pilot
may elect not to reduce TLA for vibration below 2.5 IPS time
limited to 5 minutes during takeoff or go-around or
10 seconds during the remainder flight phases. If vibration
returns to the green range within 5 minutes, the flight may
continue but vibration causes should be investigated before
the next flight. Vibration in any flight phase in the amber
range up to 1.5 IPS for less than 30 seconds does not
require maintenance action.
