Nothing! The app is completely free to download and there is no cost to register.
For a fee of £2.50/month, paid annually, pilots can access the entire Helipaddy database (including hotels, restaurants, and B&B's) and the complete set of pilot tools and features. Non-premium pilots can still:
- add as many sites as you please, with as much information attached to them as you wish
- share these pads privately with your friends
- see all aerodromes and aerial points of interest
- use all in-flight tools
Information on how to go Premium can be found here.
Pro-tip: Earn free Helipaddy Premium membership by contributing 6 or more pads to the public database or by referring a friend!
