This situation is ridiculous.
As I understand the regulations, any training flight will count, so what happens if I book an hours IMC instruction (I have no IMC rating) and ask the instructor to sign that? I may have displayed display poor skills, but that would be expected after an hour. But how could he refuse a reasonable request to sign only that he had instructed me?
Is it up to the FI to question my intentions before signing the flight details? It puts the FI into an intolerable position .
Also, why do I need a signature in the first place? I have an invoice stating that training was provided and can cross reference my logbook with this document.
The reality is that we all know what makes sense (BEagle has stated it clearly), but this stupid situation creates loopholes and could benefit the cynical rather than the honest pilots who are really concerned with safety.
