INTRODUCTION
This manual describes the operation and calibration of the Penny & Giles Aerospace Limited Pitot-
Static Leak Tester (PSLT) Type 051600. The PSLT, known as the 'Micro Leak', provides 1 st Line leak
testing of aircraft altitude and airspeed systems. It also provides limited pressure control for the
functional testing of pneumatic switches.
