Strim,
Its been a while since I have been involved in flying training, but what disrespect can flying schools show to mutual training for an instructor rating? It is supposed to be the equivalent to solo practice that is included in other areas of the licence syllabus. A time to practice and consolidate what was learnt with the Grade 1 instructor. The only way there could be a lack of respect for this time is if the individual trainee chose not to use it wisely???
