Over land, maintain 35,000 ft or below to keep your speed less
than Mach 0.98.
When over-land restriction ends, climb at 1200ft/min, activate
afterburner and accellerate to 530 KIAS. Barber pole limit will
restrict acceleration until passing 33,000ft.
Disengage after-burner at M1.70.
Note: Almost all flight Simulator aircraft have a dramatic increase
in air density programmed in between M.90 and M1.2. Above M1.20 the
resistance no longer increases at a dramatic rate. This means rapid
acceleration will begin after M2.0.
It is important NOT to fly near or at M1 too long.
This will reduce your fuel range.
At M1.70 and above 45,000ft, slowly accellerate to 530KIAS switching
to M2.1 using normal power and 1200ft/min decreasing climb rate to
maintain 85% N1 or less. You should reach Mach 2.01 by 50,000ft then
switch to "cruise climb" mode by decreasing climb to +100ft/min. to
57,000ft heading east, and 59,000ft heading west.
FUEL MANAGEMENT and CRUISE (auto-pumping):
On short flights (1500 miles or less) no fuel management is required.
When traveling near maximum range the following is required:
When you have traveled 1,000 miles or more, watch your forward middle
fuel tank carefully. When it indicates "1.5" place the fuel pump in
manual pump AFT position and pump all the remaining fuel from forward
middle into aft middle and empty the forward tank. This will cause
the COG to shift near the extreme aft.
Place the fuel pump on MANUAL STOP. Placing the pump in stop will
prevent it from pumping the fuel back into the forward tank immediately.
This will gain you 300-500 more miles before the GOC
lamp comes on FORWARD. I think the lamp is coded into the gauge.
It's no longer needed in this flight model although it can be taken
as a reminder you are on the bottom half of your fuel tanks.
You don't need any fuel in the forward tank during cruise, and it would
normally be lost from being burned. You need this fuel in the rear tank
later when the main L+R tanks are not full enough to hold the tail down
by themselves. If you prefer manual pumping, do not use the AUTO
position.
Descent:
Near the end of your flight the forward COG warning light will come on.
You can ignore it. Sometime later, the COG light will begin to flash.
You can also ignore the flashing as long as you have the proper fuel
calculation in loading your aircraft and you have performed the
pumping operation above.
375 miles from destination, slow gradually to 350KIAS indicated
while still level.
Begin your descent to -1500ft/min. 350 miles or less from your
destination depending on altitude.
The faster and shorter your descent, the less fuel you
will use, and the sooner you will recover COG.
You will notice the COG start to recover as you slow down. You will
eventually get it back in balance and start to go rear heavy.
At this time, you need to place the fuel pump back in AUTO to pump
fuel forward if there is any left in the rear tank. If your rear tank
is empty, don't worry. Your main tanks are also probably empty
enough to keep the rear from getting too heavy.
When you get near M1.1, decelerate rapidly to 300KIAS, reducing descent
to 1200ft/min or less.
It is important to prevent flying too long around M1 which is
maximum air density.
