All,
There is a golden rule: 2 approaches max then divert. Ignore this at your cost.
Sensible decisions at the planning stage in the crew room must always ensure at least one workable alternate airfield. If you can't find one, don't leave the ground. Always look at your planning minima for diversions. If the alternate airfield can provide a CAT 1 ILS, only use it if the weather on the day would ensure a successful approach if you could only use a non precision aid for its expected runway in use. This is just the most simple and basic of planning considerations and if you don't understand this you should not be flying and you are plainly not a professional or even just a competent PPL.
