What you have to ensure is you compare like for like.
Sounds strange , but there are several ways to calculate an hours flying.
- Brakes off to brakes on.
- Tacho time
- Hobbs meter
- Airborne time plus 10 minutes
- Aircraft type
all spring to mind.
Also does the rate include landing fees? does solo flying get charged at dual or solo rate whilst a student? and proably several other variations.
So it maybe does not answer your qustion, but hopefully does gives you some help in comparing prices.
