This is a career track rather than a hobby program. $89,000 takes someone with no flight time through the private pilot certificate, the instrument rating, the commercial certificate and the multi-engine rating, in that order. What it does not buy is the 1,500 hours the airlines require, which most people build by instructing after the commercial and are paid for. That gap is the part worth understanding before anything else is discussed.
Anyone leaving a well-paid Westside career for this should look hard at the shape of airline pay rather than the headline figure. It is seniority-based and back-loaded: the early years are lean, the later ones are not, and the whole thing is bounded by a retirement age of 65 in the United States. The arithmetic looks very different at 26 than it does at 46, and we would rather work through it with you at the table than have you discover it in year three.
Full-time training works best when you treat it as a job you commute to, and fifteen miles over the Sepulveda Pass is a commute you will keep making. Van Nuys is one of the busiest general aviation airports in the world: two parallel runways, a control tower, Burbank's Class C alongside and the Los Angeles Class B shelf overhead. You will make more genuine decisions in your first hundred hours here than in a year at a quiet field.
