Line a 20x10x6cm terrine dish or loaf tin with fat and spoon in the mixture. Cover tightly with foil or greaseproof paper and put in a roasting tin on the middle shelf of the oven. Pour in boiling water to two thirds of the way up the terrine. Bake for about 70 minutes until the internal temperature reaches 65-70C or until a skewer inserted into the centre comes out warm all the way through. Put a plate on top of the terrine, weigh down with a couple of tins and allow to cool.
Qualifications. In 2011, salaries for aerospace engineers could top $147,810 per year or $71.06 per hour. They could also fall to less than $65,310 per year or $31.40 per hour. To earn this range, engineers need a minimum bachelorâs degree in aerospace engineering or a related subject.
All government workers, including aerospace engineers for the Air Force, use the same General Schedule pay tables. This divides salaries into grades, based on education, experience and position. It further subdivides grades into steps, which are intermediate earnings between grades. Aerospace engineers start at GS-7. According to the Office of Personnel Management, the base salary for that grade begins at $33,979 per year for step 1 but can increase to a maximum of $44,176 at step 10. At GS-10, step 1, salaries start at $45,771, and at GS-15, the highest grade, they start at $99,628. The maximum step 10 salary for this grade is $129,517 per year. Recognizing that costs of living vary by area, the government also uses locality tables to vary the salary of aerospace engineers in the Air Force.
