I wouldn't expect to have to carry the MoT in the car though.
Utterly daft to expect the CofA to be carried on all instructional flights within the UK FIR. A copy, perhaps - but why? The original should more sensibly be kept safely on the ground. Worst case - aircraft crashes and burns out completely. Where is the C of A? Err - this bit of ash here, I think?
So - a flight that lands at another aerodrome and then comes back again may (or may not) be considered 'one flight', depending on which Belgranist one talks to?
Student flies 3 flights A to B, B to C, C to A. Three separate flights? Not for FI '25 solo sign off' purposes, according to LASORS.
Student flies 3 flights. Walk out, start up, take-off, fly 1 circuit, land, taxy in, shut down, get out and walk to club. Repeat x 2. 3 separate flights - nothing to say they're not......
Daft ideas can spring from the Belgrano before their impact has been properly addressed.
