What is a private pilot licence?
A Private Pilot Licence lets you fly an aircraft privately, with passengers and also abroad. For many people, it is a goal in itself, while for others it forms the first step of a modular route to becoming an airline pilot. If you are also a flight instructor, a PPL allows you to give paid instruction for the LAPL and PPL.
Whether obtaining a PPL or LAPL beforehand is a good idea depends on your route. If you are aiming for an integrated course or a cadet programme, many experienced pilots say a PPL offers little advantage in the training itself, as you go through the whole programme anyway and in their view classmates without experience reach the same level within a few weeks. It does show motivation, and you find out relatively cheaply whether you really enjoy flying. Gliding is mentioned by several candidates as a cheaper alternative that also provides a valuable foundation. If you choose the modular route, the PPL is simply your first module. Bear in mind that your licence keeps costing money, because to stay current you need to fly regularly.
You take PPL training at an approved training organisation (ATO) or a declared training organisation (DTO), as both may offer the PPL. Check which airfield you fly from; if it is day VFR only, this limits your options if you later want a night rating or IR.
