It is not possible.
Yes. A valid photo license is an acceptable form of id.
No, but you have to have a pilot's license.
No.
If you are an Irish or British citizen photographic ID will do, including a driving license. As a general rule, always use a passport for travelling.
A driving licence allows you to drive cars and other road vehicles it does not allow you to fly an aircraft. You would need a pilots licence in order to fly to Scotland from England or you could just buy a plane ticket and someone else will fly you there.
A photo identification is necessary to fly from England to Northern Ireland. The airlines prefer a driver's license or passport identification picture. The passport is not necessary if the person flying is a citizen of either country.
Approx. 3 h 30 min (directly).
Yes. I used my provisional licence to go from Bristol to Dublin and I'm from the UK.
Not legally.
You can only use a UK drivers licence as proof of identity to fly within the UK. If you want to fly abroad - you will need an internationally recognised passport.
Your destination is irrelevant. It's your starting point that is important. Check with the airline that you intend to fly with as they all have different rules. As a general rule a passport and not a driving license would be necessary to fly into Scotland. It still depends on your starting point. If that is within Europe, you may not need a passport. As I said, check with the airline that you intend to fly with.
Legally you don't need any. However, because of increased security recently, airlines won't allow passengers to board a flight without acceptable photo ID. The most acceptable ID is a current passport or photo-card driving licence.
