We're getting a little off topic here but every type of entry level job in aviation has its inherent limitations:
- Flight instruction
- Banner towing
- Para dropping
- Traffic watch
- Fire watch
- Sight seeing flights
Some of the above should really only be done for one season 400-500hrs max as they offer nothing but Total Time.
I'll still list flight instruction on top because if you do it right it does wonders for your people skills and out for all of the above does allow you to fill some more columns in your logbook such as Night, XC, IFR, IMC, ME and generally a boatload of Instrument approaches.
