Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what the (a) rank and (b) length of service was of each RAF engineer (aerosystems) officer who left the service in each of the last five years for which figures are available.
The information requested constitutes personal data and is prohibited from release under the Data Protection Act 1998.
However, based on the information held from 1 April 2011 – 31 March 2014, the average total length of service on exit by rank for the Engineer (Aerosystems) officer is as follows:
| Rank (RAF Engineer (Aerosystems)) | Average length of sevice |
| Junior Officers | 12 years 0 months |
| Squadron Leader | 20 years 0 months |
| Wing Commander | 26 years 7 months |
| Group Captain | Insufficient data to provide an average*. |
*The small number of Engineering (Aerosystems) Group Captains during the period 01 Apr 11 – 31 Mar 14 means the resulting ‘average' would be misleading.
