I Bombed in Indianapolis

here's something wrong with this place. First a wicked crosswind came out of nowhere just as we were on final approach for landing and we found ourselves flying a few feet above the ground moving at 150 knots, eyeball to eyeball with the diners in the airport terminal restaurant. We banked sharply to the left, and applied full throttle to the engines. My left shoulder and hip dug into my seat as we pulled up into

the sky. There's going to be a heck of a report to fill out on that one.

And then we were cruising over In- dianapolis at 10,000 feet, the lights of the city twinkling below us, keeping a lazy eye on a couple of low-flying com- muter planes rising up from the airport to the west. Our USAir DC-9 was perk- ing along nicely, all but flying itself; for Capt. James Fogarty, in the left seat, and me, flying as first officer, the only task left was to sweep our eyes over the dozens of gauges and lights on the instrument panel.

All of a sudden, without a hint of trouble, the board lit up like some de- mented Christmas tree, and there was a horn blaring in my ear. “Right en- gine’s on fire,” Fogarty said, his right hand automatically reaching to the control for the manual fire extinguisher inside the engine. “I’m blowing the first bottle,” he said, and we both watched the fire signal on the panel. No luck.

a aa eo ae rs Lr os y.} ha . GIF es) Cie Th * a, "495 ee 7 1 ee F

He hit the second extinguisher switch, but the fire warning still glowed. Fi- nally, he shut down the engine and the fire quit.

Only now we had just one engine, and the uneven torque wanted to yaw our 45-ton jet into an airborne pin- wheel. But guided by Capt. Fogarty's steady hand, the rudder angled, the flaps extended, and the trim was set, and we circled gently into an uneventful night landing at Indianapolis.

I'm not even going to discuss the sleet storm that materialized out of nowhere on this fine June day, or the problems we had getting the landing gear down when the hydraulic system went on the fritz, or the airline food. We'll leave those problems for another day.

Airborne And to think we never even left the ground! The USAir DC-9 I had spent an hour “flying” was at the air-

line’s Simulation Center at Pittsburgh International Airport. USAir is button- bursting proud of the new facility, which includes five full-scale comput- erized aircraft simulators.

Before I entered the cockpit of the DC-9, Capt. Fogarty, director of flight training and standards for the airline, took me on a tour behind the curtain. From the outside, the simulator, built by Singer Co.'s Link Flight Simulation Division, looks like one of the creatures from H.G. Wells’ “War of the Worlds.” It's a room-sized box set atop four sets of gleaming hydraulic shafts.

As we watched from the outside, a USAir pilot returning to action after a medical leave (he fell through a hatch on his boat), was being put through “three bounces” by a check pilot for the airline. “Three bounces” means three takeoffs and landings, accom- panied by as many realistic vagaries as the instructor chooses to program into the flight. The room yawed from right to left; the nose pitched down; it wobbled from side to side. “Looks like

he’s going through some heavy weather,” Fogarty said.

We followed the thick spinal cord of cables from the base of the simulator down into a tunnel and across the hallway to the computer room. Each of the five simulators has its own brain center—computers divided into control tasks, instrument simulation, and creation of graphics. For the state-of- the-art DC-9, the system includes a high-speed Gould SEL 32/77-80 com- puter system which controls the move- ment of the simulator and the movement of the hundreds of dials and lights on the instrument panel. The Gould system then passes information on the “location” of the plane to a sep- arate Singer-Link computer bank that produces the spectacular view out the windows. (The graphics system is built around four Intel 8086 microproces- sors, the high-speed cousin of the 8088 chip used in IBM's PCjr micros. )

PCjr MAGAZINE 7

False Move As | found out soon af- terward, the simulator is quite capable of giving a convincing ride—pull back on the yoke, and not only do you ex- perience a sensation of gravity, but there is a palpable feeling of motion. Obviously, the simulator can't fly 30,000 feet into the air or bank into a coordinated two-minute turn—if it did, it would be an airplane. But the designers of the simulator are quite good at performing little tricks: There is an emphasis, for example, on the “onset” of acceleration or deceleration. To convince its occupants that they're in a dive, the simulator mimics the sudden change in speed and movement and then gradually (and imperceptibly) eases off and returns to its ordinary position in preparation for its next movement.

There is so much attention to detail in the simulator, it’s mind-boggling. For instance, on take-off roll you can feel the expansion joints in the runway as your “wheels” pass over them. The yoke has the same heavy feel as the real DC-9. The rumble of the landing- gear door opening and closing, or of the flaps extending into the airstream, is accompanied by a realistic buffet of the cockpit. At one point in mid-flight, I could swear I was hearing the tinkle of ice in plastic cups as the steward- esses swilled the planters with bumbo in the cabin.

USAir, like a number of other major airlines, works very closely with the simulator manufacturer to come up with a device that meets the airline's particular training requirements. Sometimes the cockpit is a salvaged nose from a plane that has, shall we Say, met an untimely demise; some- times the housing is built from scratch to be an exact duplicate of the real thing. All of the instruments are from current models of the plane now in use; each control is hooked into the computer for proper simulation. The seat I sat in ($8,000 to purchase, and not all that comfortable) had spent time in flight before being put out to pasture in Pittsburgh.

Window Seat But it is the visuals that are the award winners in the cur- rent models of simulators being in- stalled today. Since USAir's hub is in Pittsburgh, the airline’s simulators contain scenery for most of the airports in the northeast. (Indianapolis is a fa- vorite because of that airport's elec-

tronic facilities.) The instructor can set the time of day (present technology provides the most realistic views for night flying, and USAir's system is set up to simulate any hour between dusk and dawn), mix in visibility from un- limited to pea soup fog, or add a soup- con of showers or sleet.

At one point, in midflight, I

could swear I was hearing the tinkle of ice in plastic cups.

The computer has three channels of video—one for each side window and one for the straight-ahead view. Mounted beneath each window is a high-resolution (1024 by 1024 pixels), 25-inch color monitor that projects up into a specially curved mirror lens. The lens collimates the image to give the appearance of three-dimensional depth. Thus when the pilot looks up from the close-in instrument panel to the miles-off lights of the airport, it takes the proper amount of time for the eyes to shift focus.

The lights of the city shimmer in the distance, growing larger and more distinct as you approach. Overhead, identifiable stars rotate with the eve- ning. You can see the lights of other planes above, below, or to the side. Ra- dio antenna warning lights blink. The airport, with runway lights, blue-lit taxiways, control towers, and terminal

buildings, beckons your plane home.

The effect is total: Although some- where deep inside me I knew | really wasn't flying an $18-million, 110-pas- senger twin jet, my hands were sweaty and my stomach was fluttering as we lined up over the middle marker for landing.

When my tour was over, I left the training center and boarded a real USAir DC-9 for the flight back to New York. I thought about asking the pilot if he wanted the afternoon off, but then I decided he probably needed the prac- tice, so I went to my seat and dozed.

Junior Birdmen And so, the ques- tion that must be on every PCjr Mag- azine reader's mind is: How can I get one of these flight simulators for my very own? Well, there are two answers: 1. Build a 100-foot-by-100-foot hangar in the backyard, complete with massive hydraulic ram system and a computer room the size of a small house, and then install a Singer-Link DC-9 (or a Boeing 767, or a military B-52 or C- 130...) simulator. Estimated cost: $7 million, give or take a few million.

2. Turn on your IBM PCjr, insert a floppy disk in the drive, and load Mi- crosoft’s Flight Simulator game. Es- timated cost: $49.95 for the disk. If you wanted to, I suppose you could mount your entire house on hydraulic | lifts to add a bit of movement.

In case you haven't guessed, in this issue we unveil computer simulations for the IBM PCjr. It’s very hard for us to classify simulations—they’re more realistic than a Q&A educational product; they're more substantive than a game; they're more gee-whiz than a spreadsheet. And they're a whole lot of fun.

Gloria Sturzenacker, chief copy ed- itor around here, put down her pencil and picked up her PCjr to take Flight Simulator for a few spins up and down Park Avenue. Gloria, who had never before laid hands on the controls of an airplane, had her imaginary Cessna weaving near-perfect arcs in the sky. (She couldn't land it to save her life, but that’s another story.)

Greg Pastrick took a dive, sub- merging his PCjr beneath the waters of the Pacific as captain of a submarine in Gato. And Susan Sandler bellied up to the bar to prosecute a jewel thief in Jury Trial.

VOLUME 1 NUMBER 7

f your eyes light up and your pulse quickens at the thought of big money, big business and big econom- ics, read on. You'll learn about InnerLine, an elec-

tronic communications system created through a joint venture by the Bank Administration Institute of Rolling Meadows, Illinois, and American Banker, a daily trade publication for the banking industry published in New York City. Don’t let the words “bank” and “banker”

mislead you into thinking InnerLine is devoted solely to the banking in- dustry. To the contrary, InnerLine offers broad databases that reach into the realms of international investment, tax law, public relations, auditing and business management. This menu- driven service is best used as a re- search tool and a monitor of the latest economic developments in the United States and in countries abroad.

Rating Interest Given InnerLine’s sponsors, it’s not surprising that many services offered are targeted primarily

for those in banking or in closely allied professions and industries. For ex- ample, the Money Market Monitor re- ports weekly on the interest rates being paid by 200 banks on a variety of de- posit accounts. The information is analyzed on a national and regional basis.

Market Value If you're not a banker, keep in mind that InnerLine provides other valuable services for those who | are interested in the general economic picture.

Even if you religiously read The Wall Street Journal, Forbes, Fortune and Business Week, it’s possible to miss some breaking financial news. One way to fill in the gap is by electronically accessing either summaries or full stories from each day’s American Banker. You can also search for news on a particular topic and from previous days’ editions. Subscribers can order “clippings” of any story and have them sent to their electronic mailboxes. Choosing the American Banker News Service from the main menu (see side- bar below) also lets you read news bul- letins and world news briefs.

The Frost & Sullivan Political Risk Letter is another news service. The let- ter assesses—by country—the poten- tial impact of international events on foreign investments. You'll find opinion and analysis columns by specialists in economics, banking and marketing as well.

Corporate News InnerLine provides access to the Business Wire and PR Newswire. Both are used by businesses which pay to have their news distrib- uted to the media. Although this is not the place to find the scoop on corporate scandal, it does give updates on changes in corporate top management, business reorganization and expan- sion, and new marketing ventures. For those involved in corporate planning, forecasting and analysis, the Citibase Economic Series offers tables of up-to-date data and statistics for 27 economic indicators including inter- national trade, the labor force, con- sumer installment credit, the Gross National Product, personal income, and the Consumer Price Index.
