a.
Go To Ground
b.
Put both Pitot and Static in Measure mode.
c.
Then disconnect hoses.
12.
Only after the Static system is reasonably leak-tight , should you proceed to the next
step.
13.
Now that both Pitot and Static systems are reasonably leak-tight, start your checkout
procedure for checking the instruments inside the aircraft. At this point you may want
to execute the appropriate Profile for your test.
Caution: During your tests, do not put either Pitot or Static output in MEASURE mode
unless the aircraft is at “Ground”. Use only the Control and Leak modes.
14.
After you finish the last point of your test procedure, select Function 8: “Go to
Ground”. If you are executing a profile, this should already be part of your profile.
The targets will get set to 20 knots and 185 feet (Your Ground).
15.
After the targets have been achieved, set both Pitot and Static outputs to
MEASURE
mode. This should be part of your profile.
16.
Turn OFF the 6300-M4.
17.
Disconnect the hoses from the aircraft and from the 6300-M4.
During your test procedure, if you lose power, the 6300-M4 will maintain the pressure. When
power comes back on, the 6300-M4 and the aircraft will be at the same pressure as before
except for pressure lost due to leaks in the system.
If the 6300-M4 behaves erratically for whatever reason, turn OFF the 6300-M4 using the
ON/OFF switch on the Remote unit. Turn the unit back ON after 30 seconds and attempt to
use the 6300-M4 again.
The 6300-M4 is capable of overcoming substantial leaks in the system. It is not capable of
overcoming extremely large leaks. Therefore it is essential that the system be reasonably leak-
tight before taking the aircraft to higher altitude or airspeed. When you do a leak check at
high altitude, a leak of more than 2000 feet/min. will immediately cause the 6300-M4 to exit
the Leak screen and go back into Control mode automatically. A message will indicate that a
large leak exists. Go back to Ground and go through the leak test process shown above, to
find and fix the leak before proceeding further.
It may be helpful to keep a copy of the procedure, shown in Figure 5.1, with the 6300-M4 to
assist the operator while using the 6300-M4.
