I. Instrument Panel
A. Description
Positioned on the instrument panel are all the engine-monitoring,
Flight monitoring and navigation instruments.
The instrument panel is secured with hex-head screws to the instru-
ment panel frame, which is bolted to the forward part of the windscreen
assembly.
On the instrument panel frame are positioned the monitoring equip-
ment for the armament installation and the pressure gauge for the MW
installation (see Part 7B).
On the bottom edge of the instrument panel a hinged auxiliary panel
is attached, which can be fixed in the upward position, and that latches to
the cover of the MK 108 in the lowered position. On this auxiliary panel
the ZSK 244A is fitted (see Part 8A).
Especially sensitive instruments: AFN-2 indicator, vertical speed
indicator, artificial horizon, airspeed indicator, altimeter, and the re-
peater compass are mounted separately on an instrument Flight panel,
which is attached to the main panel by vibration dampening mounts.
B. Installation and Removal
Before removing the instrument panel. Remove the auxiliary panel;
to do this first release the latch and then attachments to the instrument
panel.
Release all cable connections on the rear of the auxiliary panel and
remove the auxiliary panel with the ZSK 244A from the cockpit.
In a similar manner, remove the instrument Flight panel from the
instrument panel.
After that remove all electrical leads, electrical plugs, piping and
Flexible cables from the rear of the instruments and remove the instru-
ment panel with the attached instruments from the instrument panel frame
after removing the four mounting screws.
When disconnecting electrical leads note that all leads are provided
with ID tags.
Seal pipe and tubing ends as well as connections on the instruments
as protection against contamination.
Installation of the instrument panel follows likewise in reverse se-
quence. The instruments are installed before the installation of the instru-
ment panel.
Attachment of the instruments to the instrument panel is almost
exclusively by slotted head screws, that are screwed into captive nuts (fixed
to the rear face of the instrument panel). When tightening the mounting
screws watch that the screws are tightened uniformly so that the instru-
ment glass is not cracked.
The limit markings are indicated on the instruments by adjustment
marks or by red marks.
