Regional pressure (QNH) we would ordinarily set for x-country. All being equal if you didnt change that and you landed at a field shown as 447ft on your chart you would have 447ft on your altimeter.
Usually an airfield will give you the local pressure (QFE) along with landing instructions. When you have landed your altimeter will show zero. |
OK, that's different. Here the field would give you "altimeter setting" which is always QNH. The "Q" codes aren't used much here.
Quote: | The reason here for having `private` fields or PPR is usually not for reasons of liability, which don`t feature as so important here as they do for you. They are usually PPR so that landing instructions can be given, `avoid flying over the village` `keep east of the railway line` `watch for electricity pylons on the approach`. That sort of thing. Sometimes it is because the local Council when giving permission for the field to be used for flying have imposed a limit to the number of landings and take offs per year. |
Liability is certainly a factor, but the major reason for private fields here is probably simply because the owner who has an airstrip behind his house doesn't want to be bothered with a bunch of people flying in and out. Listing a field for public use also may impose a higher standard of required maintenance... if you land at a public airport and bend your airplane rolling into a ditch across the runway you have good reason to be upset; at a private field it's your own fault if you weren't supposed to land there without prior permission anyway.

Hi Dana,
thats reasonable. there are very few people here with enough land for a strip unless they are farmers. The farming mafia flit happily around and seem to know where all the little strips are tucked away. We have one PPR strip on an island out in the Bristol Channel. They have a very rough strip and when you ring up they go out and move the sheep and open the gate in the wall you have to fly through on the approach.
In Australia where they have some BIG spreads some pilots never got a license as they argued that they only flew over their own land. They learned to fly from Pappy about the time they learned to drive a car. The authorities seemed content to let it go as there were not that many but then they found that that they were doing x-countries on the basis that they were always flying over there own land or that of their friends. That stopped it. Probably
Cheers
Pat
