Nope, I'm not dealing cards while I'm flying, and that's not a strange new kind of baseball cap. In this picture, I am wearing a hood which will prevent me from looking out the windows, so I will be forced to fly the airplane by instruments alone. Today, we will begin simulated instrument training in N737ME.

Instrument flying allows a pilot to fly in conditions which prevent him from looking out the window to ascertain his position, most commonly because he is flying within a cloud. In case you're wondering, when a pilot flies into a cloud, he loses all visual reference with the ground and sees nothing but white. However, the instruments in the plane still give the pilot his attitude in relation to the ground, his airspeed, his altitude, whether he is climbing or descending, and can guide the pilot directly to a runway even if he can't see it. Of course, I won't be able to master all of that until I finish my Private Pilot Certificate and start working on my Instrument Rating. For now, I only need 3 hours of simulated instrument flying to ensure that if I ever did get myself into a cloud or if I lost my frame of reference with the ground, I would be able to use the instruments well enough to get myself out of trouble.

As a VFR aircraft, we are prevented from flying into clouds because we must be able to see aircraft in the distance at all times. So, in order for me to practice instrument flying, Tom will be my eyes. While I fly the plane by responding to the information given to me from the instruments, Tom will be looking out the window, making sure we don't come near any clouds, other aircraft, or any other obstacles that will put the aircraft in danger.

While Flight Simulator is lousy at teaching a pilot how to do ground reference maneuvers or how to use landmarks to identify one's position because the scenery in the game just isn't realistic enough, as I began my simulated instrument flying today, I could instantly tell that VATSIM and FS9 are excellent tools for teaching flight in reference to the instruments. The cockpit in the computer simulation displays the exact same instruments in the same places as this real-life cockpit, and when I put the hood on today and followed Tom's directions for turns, climbs, and descents, I was quite good at hitting my headings and altitudes.

The primary instrument that I must refer to is the attitude indicator (top row, middle). This instrument verifies whether I am in level flight, climbing, or descending, and it is weighted in the bottom so that it will always tell me where the ground is. Secondary instruments that provide me with additional information are the heading indicator (bottom row, middle) which tells me the compass heading that the airplane is pointed, the altitude indicator (top row, right) which gives the plane's altitude in relation to mean sea level, and the vertical speed indicator (bottom row, right) which quickly tells me whether I am climbing or descending. Additionally, I also refer to the airspeed indicator (top row, left), but not nearly as often as the other instruments.

On a side note... the instrument that is taped over is the turn coordinator... it wasn't working when this photo was taken. The turn coordinator helps verify whether the plane is yawing to the left or right, which would require rudder pressure to correct for the yaw.

On one level, instrument flying is very liberating. I am no longer responsible for looking out the window, watching out for traffic; Tom, my safety pilot, is taking care of that for me. All I have to look at are these six little instruments. In order to receive information from all of the instruments, I must maintain a scan. My eyes jump to each instrument, my brain ascertains the information it is giving to me, my hands and feet react to that information, and my eyes move to the next instrument. The attitude indicator is the most important instrument; my eyes jump to this instrument three times as often as every other instrument. So, in short, my scan of the instruments might go like this:

1. Attitude Indicator
2. Heading Indicator
3. Attitude Indicator
4. Altitude Indicator
5. Attitude Indicator
6. Vertical Speed Indicator

... and then back to the Attitude Indicator again. I also glance over at the Airspeed Indicator and Turn Coordinator from time to time.

"Fly heading 160, climb and maintain 3,200," Tom requests, simulating a direction from Air Traffic Control.

"Heading 160, climbing to 3,200." I respond.

Banking the wings right to a heading of 160, while pulling back on the control wheel to climb. When instrument flying, the standard turn is no longer 30 degrees; it is now 17 degrees, as shown on the turn coordinator. At this bank angle, the plane takes 2 minutes to make a full 360 degree circle. This bank angle is standardized for all instrument flying, so that Air Traffic Control can predict the turn radius that aircraft are going to make. And for a first time out, I've got my heading and altitude pegged.

"Wow. I can see that instrument flying is going to be no problem for you," Tom congratulates.

Thank you once again, VATSIM!

It was quite a day. MDW-ARR-JOT-GYY-IGQ-MDW, one landing at each field, with hood work in between. My landings are spot on nowadays. I am steadily able to touch down sooner and sooner, using up less and less runway. This will be incredibly important when I perform my short field landing for my checkride. In a short field landing, I must use up the least amount of runway possible. In order to do this, I am actually pointing the aircraft before the runway threshold rather than on it, because when I pull back to flare, the plane is of course going to continue past the threshold and touch down on the numbers or before. After all of my landings were done and we were headed back to MDW, Tom made one comment that I had never heard him make before.

"Everything you did was perfect!"

Wow.

I still have lots more work to do. Only managed .4 hours of simulated instrument, so I still need 2.6 hours more. But I can truly sense my readiness for cross country solo to be just over the horizon. I still have to do 3 hours of night flying as well.

Now, will somebody please help this guy find the master switch?
