Why get an Instrument Rating?
Safety: Statistics show that instrument rated pilots have a substantially lower accident rate than VFR only pilots. More than half of the weather related fatal accidents in 1996 were due to continued VFR into IMC flight. With the training an instrument rating provides, you will have the skills to fly the airplane safely back into VFR conditions.
Flexibility: The instrument rating gives you options. You can depart on a scheduled trip when the morning fog is grounding VFR only pilots. When you arrive at your destination, you know you can descend through the marine layer that is between you and the airport.
Fun: Yes, instrument flying is fun. First you are punching through small cumulus clouds as you are being vectored to final, then gradually sinking into the stratus as you descend on the ILS. You get a sense of the speed of your airplane as the wisps pass you by. Then, descending into the marine layer, the solid gray outside gets darker as you get lower, until suddenly the runway appears before you exactly where it should be. The satifaction of a successful instument approach is one of the greatest pleasures in my flying experience.
