After nearly four years of no flying, I am again current to fly myself and passengers! 2.1 hours of instruction (over two flights) was enough to get me comfortable in the cockpit again, and my instructor signed me off for both my Biennial Flight Review and to rent aircraft from the flight school with no instructor needed to come along.

Getting back into a plane was a little weird after such a long absence…. I had to read the checklists very closely just to remember what certain things meant - even on the preflight - and I had to repeat several things because I had forgotten to do them… even though they were right there in front of my eyes, in writing, on the checklist!

I had a little trouble starting the engine on the first flight, but the second went smoothly. It didn’t feel very real to me until I started doing maneuvers - specifically steep turns - on the first flight. Once I felt the extra Gs of steep turns though, It started to come back to me pretty quickly. The first landing since October of 2003 was a little ugly - picture a dollar sign ($). The straight line is the runway and the S is the path I was flying the plane trying to land… It didn’t help that it was also at night!

The second flight we did mostly touch and goes at a small airport to the south of the field we departed from - and I started to get my bearings back on landings. By the end of the second flight, my instructor was pretty much staring out the window as I did all the flying and radio calls.

Finally! I’m ready and raring to go at this thing again… I even feel like I’m a better driver when I’m a current pilot. :)

Anybody interested in helping pay for flight training? I’ll put up a PayPal donation button soon… and tell people about this blog! Every little bit helps.

Fair Winds,
Andrew

An airplane is an amazing piece of machinery.  During some portions of a flight, it is required that the pilot make large changes and major corrections to the path of the aircraft.  Takeoff and landing are obvious places where this comes to mind.  This is called “hand flying” the airplane.

At other times, however, it is unnecessary to “hand fly” the plane - during straight and level “cruise” flight for instance.  During this phase of a flight, the pilot will use what’s called “trim” to make very slight corrections to the flight path of the airplane.  If the plane is descending slightly, the pilot will use “nose up trim” to stop the descent.  If climbing slightly, “nose down trim” may be used.  Some aircraft have trim for rolling (aileron trim) and turning (rudder trim) as well.  Keep in mind here that I am not talking about any kind of “auto-pilot;” this is just a way to more carefully and precisely control the plane once it is in “cruise” flight and flying at a single altitude and in one direction for a length of time.

This can be likened to a business (as always!).  At some points in the life of a business, like during the startup and initial growth, it is necessary to “hand fly” the business - you as an entrepreneur (pilot) must “control” the business more directly and make larger changes to its direction.  In an airplane this is during takeoff and climbout and only lasts a few minutes.  In business, it may last a few years. 

Additionally, if you plan on selling or in some other way “exiting” the business, you will, again, need to “hand fly” for awhile.  You may not be “hand flying” the business directly, but you will be directly and significantly involved in the process of finding a buyer and negotiating a fair price for both of you.  This roughly coincides with the approach and landing of an airplane - again a time when the pilot must be significantly involved in the aircraft’s control. 

Most other times during a business’s “flight,” small corrections and tweaks are all that is necessary to keep the company moving in the direction you want it to go.  This is, of course, assuming you have a good business plan (flight plan) and a good team (crew).  You also must be in a well-designed company (stable aircraft).  See my post on Tradeoffs for more on business design and aircraft design.

There ARE times during cruise flight when a business (or an airplane) DOES need to be hand flown - any time a change of direction is necessary.  In aviation, it is all about navigation or avoidance of other aircraft (which are subjects for other posts), and in business it is during times of change, when a new direction is needed to grow to the next level or to outmaneuver competition.

Times to hand fly an airplane / business:

  • Takeoff / Startup
  • Climbout / Initial growth phase (combination of trim and hand flying)
  • Change in direction / New business opportunity
  • Traffic avoidance / Response to competition (can be proactive or reactive)
  • Initial descent / Considering exiting (combination of trim and hand flying)
  • Approach to landing / Decision to exit made (combination of trim and hand flying)
  • Landing / Exit of business (sale or other exit strategy)

The reason it is important to understand this is that is is possible to “hand fly” an aircraft (and a business) when it should be “trimmed.”  It is very easy to “overcorrect” when you hand fly an aircraft during cruise flight… this will cause large changes in altitude and direction because the pilot feels the need to directly control everything the aircraft does with relatively large control movements.  But in a stable aircraft, small adjustments with trim allow the plane to “fly itself” - and that is exactly what aircraft (and businesses) should be designed to do.
