Title: What I Did on my Holiday: Pax River Manned Flight Simulator By: Jim Harler Date: 1997-10-30 1600 Flashback:Orig. Multipage Version Hard Copy:Printer Friendly
Six of us left for Pax River on Monday afternoon. We took a
mix of marketing, artists, programmers and producers. Wild
Bill arrived there late Monday night. We checked in with
the McDonald-Boeing rep, Frank Monterelli, early Tuesday
morning and he got us signed in and passes issued. We got a
quick tour of the base and went to the Manned Flight
Simulator Facility.
Since Pax is a test and evaluation base, this facility is
designed to test various a/c flight control systems and
other advanced systems. The 'stations' are interchangable
meaning that they can pull out a Hornet cockpit, roll a
Tomcat cockpit into the same station and inside of 30
minutes have it up and flying as a Tomcat. These stations
are used for testing and evaluation and not training.
We looked at the various stations and saw set-ups for
Hornet, Super Hornet, Tomcat and V-22 Osprey. (undergoing
flight testing there now.) We also saw a couple of new
visual systems they are working with, one of which is a
helmet mounted system where the world is contained in the
helmet displays. Fancy I-O glasses. VERY fancy. (grin)
Several of us got to try it out in a static stand and it
was something.
They had a F/A-18E Super Hornet cockpit in one of the
stations for us with a 120 deg visual system. Like others
here, the cockpit was used as a systems/flight dynamics
evaluation station rather than a trainer meaning it was
more up to date than most training simulators. The flight
dynamics were updated 3 days earlier based on actual flight
test data derived within the two weeks preceding and the
fidelity of the flight controls was excellent and true to
life. All displays were active and the people there were
very helpful answering questions.
I flew it first and was greeted with a 'small bug'. Seems
only one engine was on line. I thought the takeoff roll was
slower than it should be but it was still faster than an
A6. (grin) I laid it off on the non-AB takeoff and a heavy
payload since they hadn't briefed me on the Gross Weight. I
very quickly discovered it on rotation when the obvious
force generated by the split yawed me right about 20
degrees. I thought that was "odd" (stating the obvious) but
applied rudder, raised the gear and the plane climbed out,
though slowly.
It was then that I punched up some of the engine
instruments (which hadn't be displayed) and discovered the
problem. It ended up being an impressive display of the
a/c's abilities with me being able to get it airborne and
climbing single engine, no AB. Even better, I was able to
land the plane single engine. It handled very nicely and
the flight control system took care of much of the
assymetric thrust problems.
We reset the sim and I did a 'standard' (ie. twin engine
(grin)) takeoff. I concentrated on the flying qualities of
the airplane during my time to get an idea of the handling
and performance of the airplane. I first did some zoom
climbs to get an idea of ROC then some stalls and
departures. Slow speed stalls were very benign with very
little rudder needed.
There is no AOA limiter on the a/c (only g limiter) so I
was able to explore the high AOA flight regime at the same
time. It's supposed to be improved on the E/F and from what
I remember from the D model sim in Beaufort, it seemed much
less prone to wing walk. Stalls were basically mushy flight
with a high AOA and high rate of descent.
I also induced departures from zero airspeed and
accelerated modes. Departures were pretty snappy, very much
as I remember from the D model. Post stall gyrations were
sometimes very rapid and sometimes very docile. The plane
recovers very rapidly from PSG's with no control inputs.
HUD arrows indicated what I needed to do to recover to
level flight in the least time possible.
I tried a couple times to induce a spin but couldn't. The
test personnel said it's very difficult to get into a spin
and conversations with the test pilots later confirmed
this. As a matter of fact, the Navy is using the Hornet to
teach spins (because of the excellent recoverability) and
had to have the flight software modified to allow easier
spin entry on those a/c.
After we completed the simulator phase, we went over to the
hangar and looked at several of the E's and F's in the
hangar, their engines and others on the flight line. We
watched a launch of one of the E's on a test flight and
recorded engine sounds for inclusion into the game.
We then went up to the main briefing room and met with the
two lead test pilots, Commander Bob Wirt (Government Flight
Test Director, F-18 E & F Test program) and Commander
Rob Niewoehner (Lead Navy Pilot, F-18 E & F Test
program). They each spent about 30-45 minutes with us and
were _very_ open to questions concerning details on the
a/c. They also gave us a great feel for the handling of the
a/c and how it would affect missions in the future. Cmdr
Niewoehner has done all the high AOA and spin testing and
showed some cockpit videos of those tests as he discussed
them. Very interesting stuff to be sure.
Following this, we met with Mike Tribino, the F-18 E/F
Integrated Test Team, Senior Engineer. Mike answered any of
our technical questions and we gathered quite a bit of
information about the a/c's specs.
Mike took us out to the Atlantic Test Range Facility at Pax
River where test flights are monitored. All test flights
out of Pax are monitored during testing. There are teams
that are formed for each test consisting of engineers,
directors, maintenance and support personnel and pilots.
Each flight is pre-scripted down to the nth degree to
optimize the testing time and get the most bang for the
buck. The E/F's are instrumented for nearly 2000 items for
each flight. About 500 critical items are data linked real
time with the remainder downloaded upon landing.
Under a Test Director a Team will gather in one of several
test rooms where routine, day-to-day testing is done.
There's also a very large NASA Control type room where
anytest can be monitored by larger groups and where the
airspace coordination with Giant Killer takes place. Pax is
only about 50 miles SE of Washington and, needless to say,
is dead in the middle of a very high traffic area. Giant
Killer, based at NAS Oceana, controls all the restricted
airspace along the East Coast.
While there we observed flight dynamics testing going on
with one of the E's. Actually, it was testing on the 'wing
drop' problem that I'm sure a lot of you have heard about.
It was very interesting to listen to the testing
communitcations and watch the console displays of flight
controls, flight surfaces and flight dynamics change as the
pilot was describing his inputs and observations.
After leaving here we returned to the E/F hangar where we
met with Cmdr Wirt again for a walk around the a/c, more
questions and some pictures. Once again, he was very
helpful and answered nearly all of our questions very
directly. This was our last stop of the visit.
That night, Paul Potera and I drove to Virginia Beach and
went out to NAS Oceana early the next morning. Going to the
Navy's LSO School we met with LtCmdr Chris Bolt, the OIC
and Lt. Chris Blaschum, one of the instructors. We spent
all morning going over the role of the LSO, calls, carrier
specs, etc. They bent over backwards to help us including
giving us the same reference manual the give to new LSO's
and some video (with comm) of various approaches that they
use in classes to demonstrate how to/not to wave an a/c.
After lunch we went into their sim and got to watch them
wave some. The sim is a 360 degree dome with you standing
in the center on the LSO platform of a carrier and a/c
making passes. Their passes are controlled by an instructor
and the students are instructed on the proper calls.
Weather and time of day as well as sea state (we were ready
to 'display' our lunch again (grin)) can be selected.
We finished up with a visit to Carrier Air Wing Seven where
we met with LCDR Pat Hagerty, the CAG LSO, met with us and
we got some info at that level. We will be using CVW-7 in
the sim and he helped us with background there. As a note,
he also waved the first Super Hornet landings so if you
see/hear those, you'll recognize him.
We got back here late Wed night tired but happy. We got a
TON of information and it's all going into the sim. From a
realism standpoint, there won't be anything out there to
match this. All the people we talked with were excited
about the sim and willing to help out in any way they can
to include flight testing the sim. We're going to take them
up on it. (grin)
