Cessna C525 Citation line training

Line training under supervision or a so-called line flying under supervision is required by the EC 965/2012 applying to pilots in specific circumstances. We provide operators with the Cessna C525 Citation line training under supervision.

Line training under supervision (LIFUS)  is required by the pan-European aviation regulations. Line training under supervision (LIFUS)  is particularly related to commercial operations -  commercial air transport . Line training under supervision is not necessary when operating a Cessna C525 Citation airplane privately outside the commercial environment.

As a part of the approved company documents - Operations manual, every Air operator certificate (AOC) holder must have a detailed description of the procedures related to the  line training under supervision.

The requirement for  line training under supervision - LIFUS  is laid down in the Commission Regulation (Ec) No. 965/2012 for a few specific situations. The explicit amount of the legs of  line training under supervision  is specified only in connection with commander upgrade LIFUS. The rest of the supervision legs are specified in the company's Operations manual and approved by the Authority.

Line training under supervision  is usually defined by the enroute sectors. To fulfill the requirements, a specific number of the  enroute sectors must be flown by the trained pilot/supervised pilot during the  line training under supervision .

The so-called "enroute sector" is described by the Commission Regulation Ec No. 1178/2011 as  means a flight comprising take-off, departure, cruise of not less than 15 minutes, arrival, approach and landing phases .

There might be AOC companies, which use time measures to identify the length of the  line training under supervision  (ie 100 hours or 500 hours).

Line training instructor and line training captain

Line training under supervision - LIFUS  may be provided only by a pilot delegated by the company.

Procedures describing the requirements for the commanders delegated to provide  line training  are described in the company Operations manual. Different AOC holders (airlines) are using different identification of such commander.

Usually, the commander delegated by the company to provide  line training under supervision  is identified as:

  • line training captain
  • training captain
  • leading captain 
  • line training instructor
  • selected commander

Usually, the specific experience and additional ground theoretical knowledge and flight/simulator training is required to become a  line training instructor .

In accordance with the FCL.910.TRI(a), even the Type rating instructors with their restricted privileges to conduct trainings only on FSTD may conduct  line flying under supervision . In this case, further training for  line training under supervision  purposes is required.

However, our instructors have full privileges of the Type rating instructor - TRI(A), so they are allowed to provide instruction on both - FSTD and actual airplane.

Generally, during the  line training under supervision , companies are applying the requirement of ORO.FC.220(b). This means, that until a successful line check, the flight crew member shall not conduct any line operations within the commercial air transport on any other type or class of the airplane.
