Excrab, thats my point. My school does exactly that, we tell them it will more than likely take longer. I always add an extra 10 hours to the JAR PPl for finance planning. Not sure what to suggest for the NPPL as I haven't done one yet!
The problem is the customer can get a confused idea of what is what when it comes to cost. Some schools I know of locally sell it as a "we'll get you through type in the time required hype".
Ruins it for the rest. Anyway that is off thread really!
Someone mentioned silcencers. Well the school I frequent is still trying to get them installed but until the Government relax a very costly legislation on silencers, they will be far to expensive for clubs to purchase.
We have some odd noise abatement issues. One involves a 20 degree track change at 100/200'. The other is a 30 degree track change, and therefore we only ask "Complex" aircarft to fly this turn as it is assumed that they are normally noisier and flown heavier by more experienced pilots.
