THE BIG GOTCHAS ENROUTE:
*Pilots continued VFR flight into IFR
conditions. This one comes up time and time again in NTSB reports. Pilots
need carefully thought-out minimums, and they also need tools to help
implement these minimums in the cockpit. The MANUAL BUILDER will do
this.
*Fuel Exhaustion. You can't just say,
"it won't happen to me." You need procedures, minimums. You need the
MANUAL BUILDER so you'll have these tools at your fingertips.
*Severe Weather. Many pilots use detection
equipment so they may deviate as little as possible. We need to use
this equipment to avoid the weather, period.
January 21, 1998 in DELRAY BEACH,
FL
Aircraft: Twin Commander
Injuries: 3 Fatal.
The pilot had received a weather briefing and was aware of the weather
conditions west and north of the airport. The pilot was issued the flight
clearance as filed, and was assigned an initial altitude of 2000 feet.
Approximately five minutes into the flight, the air traffic controller
questioned the pilot concerning the assigned heading. The controller
stated that the pilot 'sounded extremely strained' and replied, 'N269M
is in trouble.' Radar altitude data showed a rapid loss of altitude
for N269M; the last radar altitude data showed the flight at 2800 feet.
The airplane collided with the ground in a nose low attitude. Weather
radar data from the Miami Weather Surveillance Radar-1988, Doppler showed
a large, intense convective cell just west of Boca Raton between 1530:15
and 1535:57. Moderate to very heavy rain showers were associated with
the convective activity. A review of the radar data showed that N269M
was 3.5 to 4.0 miles north of the core of the large convective cell.
The National Transportation Safety Board determines the probable cause(s)
of this accident as follows:
The pilot flew into known convective meterological conditions and lost
control of the airplane. Factors were low clouds, and moderate to heavy
rain.

The ENROUTE
PHASE
On some days, the enroute phase of a flight
can be very boring; on other days it can be the best part of a flight.
So enjoy the view, the serenity and the privilege of flight. But remember,
there are tasks to be completed.
Every pilot knows that the following things will have to be done at
some point, before he or she lands:
· Go through the cruise checklist.
· Receive ATIS information for the destination airport.
· Review obstacles at the destination airport.
· Review arrival and/or approach procedures at destination airport.
Some of these items will have been reviewed during the preflight and
planning phase. In that phase, we insured that all our runway and airport
facilities were adequate. But arrival and approach procedures change
with the weather, so be prepared for other contingencies. It's always
a good idea to complete your tasks sooner rather than later. For example,
try to receive your ATIS information as soon as possible, and try to
review the obstacles, arrival and approach information as soon as possible.
The reason for this is that these tasks are "known" tasks—you
know you'll have to do them. There are an infinite number of unknown
tasks that could pop up at any time, so it's best to get the known tasks
out of the way. The more diligent we are in the beginning, the more
time we'll have to deal with unforeseen situations later. These situations
don't need to be emergencies to throw you for a loop. Something as simple
as ATC expediting your arrival, or maybe a short turn to final or a
short turn onto the approach, can make a pilot very busy. In this section,
we are going to talk about enroute procedures and cockpit management
concepts.
Let’s begin the enroute phase with the climb-out. We ended the
last section (the Takeoff phase) right after takeoff. In the preflight
briefing (done with two pilots, or just in your head) we talked about
reviewing the departure. Route – What is your first heading and
altitude after takeoff? What is your first fix?
Climb-out - Since you reviewed the departure in your head, there is
no scrambling for charts or programming of navigation equipment needed
at this time. FLY the airplane first and when you're able, reply to
ATC instructions as expeditiously as possible. Complete your “after
takeoff” checklist to insure the aircraft is cleaned up and nothing
is forgotten. If you are flying in a high density area and have an autopilot,
it’s good advice to use it. A modern professional cockpit is managed,
not flown. Hand flying should be done where altitude bust or other errors
will not result in a midair collision. CRM (crew resource management)
is a management of all your resources. On an ATP (airline transport
pilot) check-ride, an applicant would probably fail the ride if he/she
did not use the autopilot for some part of the flight. Part of good
cockpit management is delegating tasks and, of course, turning on an
autopilot is delegating the task of flying to allow you to attend to
other jobs.
Just as we discussed in the Takeoff phase, you should refrain from unnecessary
conversation, maintaining a sterile cockpit till cruise. Look to the
Manual Builder for more insight on the Sterile Cockpit.
Every flight is unique. The enroute phase can be very short or very
long. The weather can cause you to travel many miles out of your way,
or it can be smooth and clear. The main issues a pilot deals with enroute
are:
Weather
Fuel
Course Track
Obstacles
Time
It helps to have SOPs—Standard Operating Procedures. Pilots should
have a procedure in place to scan the instruments for signs of trouble.
Pick something that works for you in your airplane. An example might
be:
Every time the clock is on a quarter, check engine instruments, check
course, check fuel, check ETA.
Every hour on the hour, check weather (this time can be adjusted depending
on the weather.)
Callouts - Callouts are used to maintain situation awareness in various
phases of flight. Just as in the Takeoff phase, these procedures can
be used in a one or a two pilot crew. If you are not in a two pilot
crew, you should complete these tasks in your head. If you ever have
the opportunity to fly in a professional cockpit, everyone will be amazed
at how fast you pick things up.
In cruise, the callouts generally required are for altitude changes,
and also when approaching an altitude while climbing or descending.
When the aircraft approaches 1000 feet to go to an assigned altitude,
the callout by the non-flying pilot would be:
PNF (pilot not flying) - Out of 4 for 5 thousand feet.
PF (pilot flying) - Roger, we are armed and engaged for 5 thousand feet
(flight director is armed and autopilot is on). or...
Roger, we are armed and hand flying to 5 thousand feet (flight director
is armed and he/she is hand flying the aircraft).
Note: This example is for a two pilot crew with
autopilot and flight director. Develop a procedure that works best for
the type of flying you do, and then use it diligently.
This insures everyone is in the loop, and both pilots then monitor
the capture and level-off by the flight director/autopilot.
When ATC assigns a new altitude, the PNF places the new altitude in
the altitude window and reads back the assignment to ATC. The PF then
will usually acknowledge the new altitude so that both pilots can confirm
they heard the same number, it made sense, and that the new clearance
is being complied with...situation awareness.
Situation awareness is a term generally used for IFR flight. It means
the pilot is completely aware of his/her aircraft's situation. This
includes the aircraft's:
· Attitude
· Configuration
· Heading and location
· Relationship to fixes and the airport
· Mechanical condition
Losing situation awareness usually occurs when a pilot is overloaded,
either by a distraction or by operating in a situation above their skill
level. It's easy to get tunnel vision and lose the big picture. This
could happen during VFR, but it is more common during IFR.
Finally—A professional is always doing something. It is important
to relax and regroup, but being diligent and prepared for the next phase
of the flight is paramount if you want to stay ahead of the airplane
and not be “hanging off the tail,” as they say. Being ahead
of the plane and being prepared means using the slow times to catch
up and get ready.
Most pilots enjoy having a good conversation in route, or watching a
beautiful sunset, or viewing the skyline of a great city. Most of us
started flying because it was exciting and enjoyable. I believe if you
practice these techniques, if you are well prepared ahead of time, and
if have clearly defined boundaries and limitations like the Personal
Operations Manual, you will find you’ll enjoy flying more than
ever. It will change the way you fly, and transform the way you look
at aviation. You will be more relaxed and confident and better able
to enjoy your flying.
