Weather Unit – 11:03 P.M. / 0603Z
Even
after thirty years, Rick was surprised at how fast Mother nature could
throw a curve. He looked at
the weather reports and radar returns and saw how fast things had
developed. Rick had called
the Los Angeles National Weather Service forecast office and talked to
the meteorologist there. He
was just as surprised at how fast the thunderstorms had developed.
He told Rick that he would alert the Severe Storms Forecast
Center in Kansas City. As
Rick adjusted the Doppler Radar display, the Area Manager in Charge (AMIC)
Tom Lamond, came over to the weather unit.
“What’s going on, Rick?” Tom asked.
Before Rick could respond, Tom added jokingly. “You couldn’t
wait another hour till quitting time?
You had to go and start some thunderstorms because you were
bored?”
“I just thought I’d give you something to do before you went
home, since you had it so easy tonight,” Rick responded.
“The American taxpayers deserve some work out of you.”
Tom looked at Rick and said, “It’s not like YOU were
overworked tonight either.”
They both laughed as Tom asked Rick to explain what was
developing and how the weather was going to affect center operations.
Rick explained, “This is an unusual pattern, Tom.
You know how hot it was today.
Some areas of the desert and in Death Valley were over one
hundred and fifteen degrees.”
Rick pointed to a weather map and continued, “There is what we
call a “Heat Low” that runs through the desert area from Mexico to
north to Oregon. Today’s
high heat along with a very low pressure gradient caused moisture to
flow up from the Gulf of California.
Normally, these thunderstorms form further east of this area,
over toward Phoenix.”
Rick drew a line on the surface map from Phoenix north to Salt
Lake City.
“Today, because of the low pressure, the moisture came in and
formed the storms here,” Rick said as he pointed to the storms that
had developed in the Palm Springs and Twenty Nine Palms area.
“Just be glad these storms developed this late and not during
the busier part of the day,” Rick said.
Tom could see that the storms had developed right over the south
portion of the Civet arrival and Lax Two departure route.
Had this developed during the day, traffic in and out of Los
Angeles and San Diego areas would still be backed up.
Rick turned to Tom and said, “We have another problem that you
should be aware of with this system.”
“What’s that?” Tom asked.
Just as Rick was about to explain, his telephone rang.
“Hold that thought,” Rick said as he reached for the phone.

Before Eric could
reply, Patty called, “Suncom one, say your altitude please.
I show you at one two thousand five hundred.”
Eric and Ron both looked at the altimeter and saw that they were
five hundred feet low. “We
are climbing back to one three thousand,” Eric replied, “And thanks
for the information.”
Eric and Ron both exchanged glances, both wondering how they lost
five hundred feet in altitude.
“Suncom one, you are clear of arrival traffic, climb and
maintain flight level two one zero.”
Eric responded to the clearance as Ron advanced the throttles to
climb power. As the G-1
started a shallow climb, Eric turned to Bob and said, “Mr. Tatum, had
you not distracted us from our job, we would have caught that altitude
deviation. Please go sit
down.”
Bob Tatum returned to his seat in the cabin as Suncom one crossed
Daggett and turned east towards Needles, California.
Suncom
One – 11:23 P.M. / 0623Z
Eric was still dumbfounded by what was happening.
The G-1 was climbing slowly through fifteen thousand when the
climb slowly stopped. The
autopilot kept advancing the throttles in an effort to keep the aircraft
climbing. Eric and Ron both
computed, in their pre-flight planning, that the G-1 would have no
problem climbing to flight level two one zero.
No matter that the engines were almost at full power, the G-1
would not climb. In fact,
the aircraft was now in a three hundred foot per minute descent.
Additionally, the controls were very mushy. Only the rudder seemed to respond to any control inputs.
ZLA
Sector 19 – 11:25 P.M. / 0625Z
Patty radioed Suncom one. “Suncom
one, Los Angeles, have you figured out what the problem is?”
For about ten seconds there was silence, then there were several
short radio transmissions.
“Los Angeles, Suncom one…we currently have full power applied
to the engines….They are operating normal….However, we cannot hold
altitude. The aircraft
keeps descending….The controls are not responding properly….We have
put in a full left turn deflection to turn, but the aircraft is turning
very slowly. We are trying
to avoid both the restricted area and trying to keep away from the
thunderstorms….I’m ….I’m still not sure just what is wrong.”
Tom and Patty looked at each other quizzically as the pilot
spoke. Tom looked up at the
ceiling after hearing the pilot’s description of what was happening.
Tom repeated, “Full power and still descending?”
“Tom,” Rick said. “I
may know what’s wrong.”
ZLA
Sector 19
Suncom One – 11:31 P.M. / 0631Z
Patty looked at the Suncom one data block on her radar screen. The altitude readout showed ten thousand four hundred feet.
“Suncom one,” Patty radioed, “The minimum safe altitude I
can assign is eight thousand, five hundred.
Descend and maintain eight thousand five hundred.”
The reply came quickly, “Los Angeles, I’m not sure that is
going to be low enough for us to build up our airspeed.”
Eric continued, “Unless we can find some cooler air we are
going….stand-by Los Angeles.”
Patty was startled by the abrupt stop in the radio transmission
from Suncom one. There was
silence on the frequency for about thirty seconds.
Staring at the G-1’s data block, she thought for a moment that
Suncom one was turning right.
It was!
Suncom one was in a slow right turn heading toward the
thunderstorm area. Patty was about to warn the pilots of what she observed when
Rick spoke.
“He is heading toward the thunderstorms.
He knows that there is cooler air around and underneath them.
Because they are so low already, he knows that it is the best
chance they’ve got.”
