With only 2 weeks to go you are cutting it fine, although after three previous sitting you should have a very good idea what`s in store. My advice would be (from someone who needed a fourth attempt at POF) to go through as many exam type Q`s as humanly possible in the short time left. Make out a sheet of "key facts" and "mnemonics" and bring it everywhere with you; on the bus, train, plane etc. Bring it to the exam center with you and read it, right up untill you go in. There are some very usful mnemonics for compass and gyroscope errors that may get you an important point or two! Here are some you may already know!
for gyro`s it goes - REST IN BED TAX`D - R - T 1
E I A 2
S I X 2
T - D 2
Reading from the top line down, R = Rate gyro, E = earth rate gyro, S = space gyro and T is, oh can`t remember(turn gyro?) The rest will take me for ever to type, but someone will explain the gimbals and axes etc,
I`m sure you`re aware of the "Chicken Tikka Masala" for speeds of CAS, TAS and RAS, (know the graph), and another example is for compass errors!
for compass errors - NUNOS(Funny enough!) goes - in the "N"orthern hemisphere, "U"ndershoot through "N"orth turns and "O"versoot through "S"outh turns.
Write these down once the clock gets going to help clear your mind and DO NOT PANIC, instruments from what I can remember, is not a "pushed for time type exam.
GOOD LUCK AND BE CONFIDENT!!!!!!!!!!!!!!!!!
Hope you can understand the above!Sorry but the typing went out of alinement...... there is another I forgot to mention, it`s for instrument errors and goes- SOD, SUC, POD,and POC. again you most likely know this,
goodluck again!
