The set of charges to which one of the two pilots who
had to eject from the Aero L-39ZA Albatros aircraft

TVM. Only the URM - 1 is missing in this shot,
which remained with the seat. It is worth noting the
marking of individual pyro cartridges with the fuselage
number of the aircraft and the Roman numerlas
‘I’ - front cockpit and ‘II’ - rear cockpit.
Arming Pins
For ensuring safety during servicing of the
emergency systems and maintenance on a whole,
arming pins are used. These items negate the
possibility of accidental firing off of charges in the
various mechanisms where they are found. The pins
are removed immediately before flight and replaced
immediately after.
Numerical designations of the pins:
1. Pin for emergency canopy jettisoning system
2. Pin for initiating charges on the right side
of the seat
3. Pin for the shoulder strap tightening system
4. Pin for the telescopic ejection mechanism
5. Not used
6. Pin for initiating charges on the left side of the seat
7. Pin for cover jettison
Pin insertion procedure in both cockpits:
Prior to pilot leaving the aircraft:
- Pin No.7 into the canopy jettison mechanism
- Pin No.4 into the telescopic ejection mechanism
- Pin No.3 into the shoulder strap tightening system
- Pin No.1 into the emergency canopy jettison
After pilot leaves aircraft:
- Pin No.2 into the tie rod system on the right side
of the aircraft
- Pin No.6 into the tie rod system on the left side
of the aircraft
