I am a Microlight pilot (Ultralight for U.S folks) with an NPPL(m) rating. The minimum requirements for bi-annual license renewal is:
- 12 hours flying
- 12 take-offs and landings
- 1 hour of instruction
- Of which 6 hours minimum must be in the 12 months preceding license renewal
Again, to emphasize, this is every 2 years.
Now, in my experience, I feel very rusty after anything more than 2 - 3 weeks off. With these rules, you only need to fly for an average of 30 minutes per month, or 1 hour every 2 months. In theory, when you get your license renewed, you might not have flown at all for 11 months.
My question is - from more experienced pilots (I am under 100 hours), what is the actual safe minimum amount of flying one should do on a monthly basis to maintain, and ideally improve, skill?
