Narrative:

Controller cleared me for the approach with 3000 ft min altitude and decrease upon interception with GS. I misread my GS indicator and decreased altitude after interception. Noticed full deflection on GS so decreased more, misinterpreted. Controller stated 'altitude alert' told me to climb and intercept -- I did. -- I need more and frequent flight time IFR. I had made this mistake in my early training. Violate air traffic area, conflicted with controller's instructions, unintentionally. I appreciate this option and please continue your services.

Title: A LOW TIME PRIVATE INST PLT GOT LOW ON THE GS.

Narrative: CTLR CLRED ME FOR THE APCH WITH 3000 FT MIN ALT AND DECREASE UPON INTERCEPTION WITH GS. I MISREAD MY GS INDICATOR AND DECREASED ALT AFTER INTERCEPTION. NOTICED FULL DEFLECTION ON GS SO DECREASED MORE, MISINTERPRETED. CTLR STATED 'ALT ALERT' TOLD ME TO CLB AND INTERCEPT -- I DID. -- I NEED MORE AND FREQUENT FLT TIME IFR. I HAD MADE THIS MISTAKE IN MY EARLY TRAINING. VIOLATE ATA, CONFLICTED WITH CTLR'S INSTRUCTIONS, UNINTENTIONALLY. I APPRECIATE THIS OPTION AND PLEASE CONTINUE YOUR SVCS.
