Hiring headsets, life jackets and life rafts can add a few pounds to the overall spend and these can vary from club to club or individual pilot.
Some flying clubs require temporary club membership that can be purchased on the day, this varies from FREE to an average of about £10-£15.
Some clubs also hire out folding bicycles to take on your trip but don't forget that the pilot must complete a weight & balance check if you're taking an unusual load.
Aircraft are typically available at an 'all in' hourly rate. Some clubs may charge +5mins either side of the actual airborne time in order to calculate a fair usage vs. charge amount.
For example, 1hr of actual flight at £100ph might equate to £110 being shared equally amongst those flying. If 4 were flying, then that equates to £27.50 each.
The pilot must be included in the share and pay at least an equal amount to those sharing. The pilot may contribute a higher proporition but the passenger may not.
If you are staying away for the night then you are likely to incur taxi and accommodation costs at your destination airfield.
The cost of taxis can vary from location to location and it is best to estimate these in advance of travel to your chosen aerodrome.
Accommodation is a far more subjective affair and should be discussed with the group, since the cost of separate taxis to different hotels may not have been anticipated.
Another variable cost relates to food and drinks. Some folks like to dine in style whilst others do not.
This topic is a must to discuss before you go flying. Whilst it is very much a personal choice, it depends on whether the flying group is going to be cohesive or independent.
If the pilot refuses to take anyone on board that has had any alcohol at all, then that is his or her prerogative.
Weather systems can appear and catch out even the most well-planned pilot. It is therefore sensible and safe for the group to plan alternate landing sites should the weather prohibit safe transit or landing at the intended aerodrome.
The flying group needs to be prepared for an eventuality like this, which may mean an unexpected stop over in an unexpected location.
This should be discussed before setting off, the last thing you need is ill-feeling & disagreement amongst the group due to the weather.
