Narrative:

While on vectors from phl approach control for a practice ILS runway 24 pne in VFR, I was given a heading that turned me directly towards the ttn class D airspace. I asked phl approach control if I was cleared into the ttn class D and was told 'no.' I immediately executed a left turn to avoid the ttn class D airspace, and most likely missed it by 1 NM judging by the GPS moving map. In the future, I will avoid practice IFR procedures during times where ATC is 'overly busy.' note: this situation occurred in VFR under flight following with phl for IFR training. No flight plan was filed for the short trip.

Title: A28 ON ASSIGNED ATC VECTOR INITIATES TURN TO AVOID CLASS D AIRSPACE.

Narrative: WHILE ON VECTORS FROM PHL APCH CTL FOR A PRACTICE ILS RWY 24 PNE IN VFR, I WAS GIVEN A HDG THAT TURNED ME DIRECTLY TOWARDS THE TTN CLASS D AIRSPACE. I ASKED PHL APCH CTL IF I WAS CLRED INTO THE TTN CLASS D AND WAS TOLD 'NO.' I IMMEDIATELY EXECUTED A L TURN TO AVOID THE TTN CLASS D AIRSPACE, AND MOST LIKELY MISSED IT BY 1 NM JUDGING BY THE GPS MOVING MAP. IN THE FUTURE, I WILL AVOID PRACTICE IFR PROCS DURING TIMES WHERE ATC IS 'OVERLY BUSY.' NOTE: THIS SIT OCCURRED IN VFR UNDER FLT FOLLOWING WITH PHL FOR IFR TRAINING. NO FLT PLAN WAS FILED FOR THE SHORT TRIP.
