I have personal experience here and it is a bad one. I had approached them for renewal of my licence. I needed to fly 3 hours. The offical told me that it would take 2 days at the max.
I was given the contact details of the concerned flight instructor. The instructor informed that there was fuel shortage and that I would have to wair for a week. This delay was very disturbing for me.
A reputed flying school like Bombay Flying Club does not have fuel! Sad!
Secondly their flying happens in dhule which is not an easily accessible place from Mumbai. That airport does not have instrument landing facility hence they have to fly to another airport for that exercise. Again that is very disappointing.
The charges they quoted were also a little steep compared to some other flying clubs. Well in my case that fuel shortage delay kept increasing and that instructor had told me she would get back to me when she finds a slot for me. However that never happened. I never got that phone call and I eventually went to a flying club in hyderabad as I couldnt wait any longer as my licence expiration date was fast approaching.
Overall anyone can conclude how unprofessional and careless the staff and instructors here are. I would not recommend Bombay Flying Club to anyone. Sorry guys.
