"TAI" on 757
Have spent eons recently in passenger mode on B737's and often seem to end up just forward of the starboard wing - so am familiar with the little stickers that say "13 feet" away from engine during ground runs, and "Starter Overide Access Hole", and "Don't open cowlings until leading edge slats retracted and disarmed" - etc. etc.
Today, however, ended up staring at the cowls of a 757 and saw "TAI Pressure Indication" and "TAI Pressure Vent".
TAI ?

Hi there.
Yes, you´re right.
On most jet engines you have an anti-ice-system for the engine intake (cowl leading edge), using hot bleed air to prevent ice-built-ups.
TAI = thermal anti-ice

The TAI Pressue Indication hole is to indicate when there is a leak in the ETAI ducting. The anti-ice duct has a shroud on it so if the EAI duct is damaged, pressure within the shroud will cause a little indicator to pop-out.
The other hole is the normal vent.
