I was wondering how people log IF (sole reference) time in the JAR standard logbook which only has an entry column for IFR time?
If you follow the acceptable means of compliance (AMC) as published by the JAA then you will record sole reference to instruments time in the Remarks part of each entry.
Most of the JAA style logbooks have a section for recording monthly and annual totals in the back. If you record the monthly piston hours separate from the single engine stuff etc then even if you fly a lot there should not be that much work at the end of each month and you can check how long you have before running out of the 3 take-off and landings requirement.
The recording of instrument time is quite an important thing for student logbooks after the latest CAA note about logging instrument time on courses.
