I once had a student who was the on again / off again type. When I was working with him on his Private Pilot Certificate, he would get serious for a week then I wouldn't see him for 3 weeks. His work schedule was very difficult. Took him 2.5 years to get his Certificate along with about 150 hours. Not that he was all that bad, but just wasn't scheduling consistantly.
After that, he wanted to get his instrument. I couldn't stand to see it take him 2-3 years to complete it. So I created my own Part 61 course to do it in 10 days. He took 2 weeks off of work, and we got serious.
I had him complete his written, and then make sure he had all his XC requirements out of the way.
The first 5 days, were spent in the Class Room and SIM. Each day went something like this:
Day 1: Basic Attitude Instrument
Day 2: VOR & NDB Navigation and Holds
Day 3: VOR & ILS Approaches
Day 4: NDB Approaches & Review
Day 5: 2 LOFT Sessions
As and Example, This Was Day 3:
0800-1000: Ground Discussion of VOR Approaches
1000-1200: Sim Session Flying VOR Approaches
1200-1300: Lunch
1300-1500: Ground Discussion of ILS Approaches
1500-1700: Sim Session Flying ILS Approaches
By the end of the first 5 days, he could have passed his checkride if taken in the sim. We had logged 20 hours of One-On-One Ground Instruction along with 20 hour of Sim Instruction. I had him doing Partiel Panel NDB holds with ease. The intesity of the progam made him real proficient.
After the first 5 days, we went out to the airplane and did the same stuff there. In the briefings we did Flight Planning. We flew most flights like mini Cross Countries. Each Leg about 50 NM. Each Leg and Destination offered a new scenario or different problem.
I had more fun in that 2 weeks instructing than I did my entire time instructing. I wish I could have done that type of instructing all the time (IN A TWIN OF COURSE!). It was very rewarding to see someone go such a long way in such a short time. Best way to go! By the way, I had a career-track student once that we did a similar type progam in the Twin....This guy was sharp as a knife by the time we were done.
The only negative, however, was his lack of Actual IMC experience. We didn't fly through 1 cloud the entire time. In that short period of time, we didn't have any opportunites to "Take advantage of a 200 & 1/2 Day." But, we discussed his limitations, and he was aware of them. A few weeks after he got his Rating, we went up and got him some good actual. And he did REAL well.
Good Luck,
