Differences training to CJ4

Single-pilot aeroplane with highest MTOW ✔️

Upon completion of your C525 typerating, your privileges are restricted to variant in which you passed your C525 skill test. Due to the limited simulator portfolio the privileges are usually restricted to the Cessna 525 CJ1+ or to Cessna 525 CJ3. To fly the CJ4 you need this differences training.

Overview

 C525C CJ4 Differences Training overview

The aim of the CJ4 differences training course is to provide you with sufficient theoretical knowledge instruction as well as the practical flight training to operate the single-pilot aeroplane with the highest maximum take-off weight. Our type instructors have vast experience operating all the variants of the Cessna 525 Citation series. We can guarantee you the flawless differences training up to the highest industry standards.

The transition to Cessna 525 CJ4 consists of 08:00 hours of variant-related differences ground school, 02:00 hands-on training and approximately additional 2 hours of the supervised operational experience (LIFUS). As far as possible, ProfiPilot Training is delivering the differences training as a competency based training considering your previous operational experience and the real equipment of the particular serial number.

The CJ4 differences training course is followed by the LIFUS or so-called supervised operational experience.

Differences

The CJ4 is the single-pilot aeroplane with the highest maximum take-off weight. The cockpit of the aircraft is more airline-like compared to the other Cessna 525 Citation series. If you are coming from the CJ2+ or CJ3, you will benefit from knowing the Collins ProLine 21 as well as the comprehensive knowledge of the FMS.

If you are coming from the "lower" product line models such as CJ1/CJ2 you will benefit from the comprehensive knowledge of the systems and Collins Pro-line 21. Challenge for you will be to master the completely-new airline-line Collins FMS. There will also be a bit of relieve for you as many of the actions such as performance calculations, thrust settings and others. They are more automatized compared to the previous variants.

Should you are coming from the M2 or CJ3+, the transition might be a bit more challenging due to the different EFIS concept and FMS.

LIFUS

 

Upon completion of the familiarization the supervised operational experience or line flying under supervision might be required by the operator. In addition, the EASA CE525 OSD requires to use device for the differences training. ProfiPilot Training usually uses the aircraft of your operator for this purpose. 

The simulator for C525C CJ4 is considered to be not available, nor accessible. Due to this fact, the ProfiPilot Training is using the real aircraft for delivering the hands-on training. The CJ4 differences training delivered by ProfiPilot Training is truly a competency-based training.
