Pneumatic source choices

Engine bleed, APU bleed or external ground air can supply the pneumatic distribution system under appropriate conditions.

Pneumatic source choices

Engine bleed, APU bleed or external ground air can supply the pneumatic distribution system under appropriate conditions.

Use this as a refresher

Place the idea inside the full system chain: source/input → control → physical response → sensing/indication → consumer/result. If the quick note seems to conflict with the aircraft in front of you, stop and confirm configuration, effectivity and current approved data.

Maintenance boundary: this is a study reminder, not a task instruction.

KEEP IN MIND
  • Engine bleed, APU bleed or external ground air can supply the pneumatic distribution system under appropriate conditions.
