Line training, or Line Flying Under Supervision is enroute familiarization with Bombardier CRJ SeriesBombardier CRJ LIFUS
LIFUS should be performed in accordance with ORO.FC.220 and AMC1 ORO.FC.220(e). Furthermore, GM1 ORO.FC.220(d) provides guidelines for operators to use when establishing their individual requirements. Line training, or Line Flying Under Supervision is line-oriented flight training required by regulations in several cases. Line training may only be provided by a qualified Type Rating Instructor with a Bombardier CRJ TRI CL65 certificate with a LIFUS privileges. In most cases it is necessary to pass the Line check - ie the line check on the relevant Bombardier CRJ variant upon the completion of the line training.
Line Flying Under Supervision or simply Line training is a training usually required under following circumstances:
- after initial type rating training course on Bombardier CL65
- transition to different variant of Bombardier CRJ Series for which the difference training is required
- introducing new variant of Bombardier CRJ Series into the fleet
- as a part of so-called Operator Conversion Course
- as a part of Commander upgrade course
- when changing the Bombardier CL65 operator
- operational approval such as HUD, CATII, etc
LIFUS - commercial operations Bombardier CRJ
The duration of the line training within the commercial air transport is described in Ec 965/2012. It is necessary for the operator to consider additional line training with emphasis on specific route qualification in case of an operational change or a change in the area of operation.
This significant operational change can be, for example:
- short runway operation
- winter operation
- low visibility operations
- HUD operation
Following amount of line training is required by ORO.FC.220 for usual commercial air transport operations.
| Position | Training duration | Reference |
| Commander course (same type rating) |
10 route segments | ORO.FC.205(4)(i) GM1 ORO.FC.220(d)(c)(1)(ii)(B) |
| Commander course new type rating |
20 route segments | GM1 ORO.FC.220(d)(c)(1))(ii)(A) |
| Co-pilot first OCC |
40 route segments or 100 hours | GM1 ORO.FC.220(d)(c)(1)(A) |
| Transition to different variant | Individual |
Duration of the line training when transition from one variant of Bombardier CL65 to another :
SOE - non-commercial operation Bombardier CRJ
Gaining the hands-on experience during the line training is also required for operators operating the Bombardier CRJ Series aircraft outside of commercial air transport. Under so-called non-commercial operations the line training has not been required by the hard law, however the EASA Operational suitability data CRJ requires so-called Supervised Operational Experience, which is more-less equivalent to line training during commercial operations. Supervised Operating Experience (SOE) may be established in accordance with Part-FCL, FCL.720.A(g) through the operational suitability evaluation.
TRI must have CL65 LIFUS privileges
An instructor providing line training on a Bombardier CL65 shall be qualified as a pilot-in-command on a Bombardier CL65 type with a valid CL65 type rating and differences training for the relevant aircraft CRJ Series variant.
Instructor must be a holder of TRI for CL65 type. The TRI CL65 certificate must be either the so-called "Unrestricted" - it means without restrictions, or may be limited to provide the line training, so-called TRI CL65 restricted with LIFUS privileges. This means TRI CL65 privileges according to FCL.910.TRI(a)(1)
