Sam-MAN,
No. Instructing has various levels.
To teach PPLs, NPPLs and Night Ratings, you need:
- 200hrs flight time
- 100hrs of which is PIC
- Minimum of 10hrs instrument experience
- 300nm solo cross country with two land aways.
This is the standard Flight Instructor Course (FIC).
If you then want to add Multi-engine privileges to that, you'll need:
- 500hrs flight time
- 30hrs PIC on type
If you then want to add IRI (Instrument Rating Instructor) privileges. you'll need:
- 200hrs under IFR
All of this is on top of the basics.
For the CPL, I think it's a case of more PIC hours on a complex aircraft, maybe 500hrs.
EDIT: Is it really 800hrs for the IRI? I haven't checked LASORS - this info is similar as from an FTO.
