- Canopy pressurisation seal
- Anti G system
- Cockpit heating and defog
- Pressurisation
- OBOGS
Left side P3 port goes where
OBOGS
Right side P3 port goes where
Canopy seal, anti G, pressurisation, heating/defog
To prevent bleed air from entering cockpit which switches must be off
Bleed air inflow, defog
When will DUCT TEMP illuminate
Bleed air temp above 300F
Placing defog to on does what
Opens defog valve, sets inflow valve to high, activates AC compressor
How do you defog the canopy
Set vent control lever to canopy (activates both cockpits)
Will the canopy defog clear icing
No
How does defog affect ITT
Increases ITT for a given PCL setting due to increased bleed load
Amber CKPT ALT
Cockpit pressure altitude above 19,000
Red CKPT PX
Differential exceeds 3.9-4.0 psi
Pressurisation system begins at what altitude
8,000 MSL
Does AC impact engine perf
Negligible - may be left on for all phases of flight
