Narrative:

I was with a student on a flight from dwh to sat on an aircraft checkout/lunch trip. I had been flying with another student before we departed and was running late. When I arrived my student said that he had already filed an IFR flight plan. We discussed the fact that thunderstorm were forecast along the route of flight, and that a higher cruise altitude will be requested when airborne. This student holds a commercial, multi, instrument, rating and is also a helicopter CFI. He also has spent time in the same type of aircraft with another FBO on the airport. So I assumed that there would be no problems. While we were en route I made the mistake of assuming that my student was aware of our position. I was concentrating on his control of the aircraft. We were IMC and he was having trouble holding altitude and the desired course. After a period of time I noticed that he had not looked at the map and was not aware of our position. At that time I tuned the sat VOR to see if we had crossed the intersection. At that time center called and advised us that we were '4 mi off course on a southwesterly heading'. We agreed and he cleared to 'turn to (do not remember what the exact heading was) intercept V-68 maintain 8000'.' my student tried to read back the clearance but did not do so in the proper fashion. I did not have a push to talk switch on my headset and was unable to give the correct readback to the controller. After 3 incorrect readbacks, I took the headset that my student had on and used his ptt and gave the correct readback. I had control of communication and navigation for the balance of the trip.

Title: CFI AND STUDENT IN A LIGHT TWIN IN IMC OVERSHOT TURN ON AIRWAY DUE TO STUDENT'S LACK OF PROFICIENCY, TURBULENCE IN STORMY WX, AND CFI'S COMPLACENCY.

Narrative: I WAS WITH A STUDENT ON A FLT FROM DWH TO SAT ON AN ACFT CHECKOUT/LUNCH TRIP. I HAD BEEN FLYING WITH ANOTHER STUDENT BEFORE WE DEPARTED AND WAS RUNNING LATE. WHEN I ARRIVED MY STUDENT SAID THAT HE HAD ALREADY FILED AN IFR FLT PLAN. WE DISCUSSED THE FACT THAT TSTM WERE FORECAST ALONG THE ROUTE OF FLT, AND THAT A HIGHER CRUISE ALT WILL BE REQUESTED WHEN AIRBORNE. THIS STUDENT HOLDS A COMMERCIAL, MULTI, INSTRUMENT, RATING AND IS ALSO A HELI CFI. HE ALSO HAS SPENT TIME IN THE SAME TYPE OF ACFT WITH ANOTHER FBO ON THE ARPT. SO I ASSUMED THAT THERE WOULD BE NO PROBLEMS. WHILE WE WERE ENRTE I MADE THE MISTAKE OF ASSUMING THAT MY STUDENT WAS AWARE OF OUR POSITION. I WAS CONCENTRATING ON HIS CONTROL OF THE ACFT. WE WERE IMC AND HE WAS HAVING TROUBLE HOLDING ALT AND THE DESIRED COURSE. AFTER A PERIOD OF TIME I NOTICED THAT HE HAD NOT LOOKED AT THE MAP AND WAS NOT AWARE OF OUR POSITION. AT THAT TIME I TUNED THE SAT VOR TO SEE IF WE HAD CROSSED THE INTXN. AT THAT TIME CENTER CALLED AND ADVISED US THAT WE WERE '4 MI OFF COURSE ON A SOUTHWESTERLY HDG'. WE AGREED AND HE CLRED TO 'TURN TO (DO NOT REMEMBER WHAT THE EXACT HDG WAS) INTERCEPT V-68 MAINTAIN 8000'.' MY STUDENT TRIED TO READ BACK THE CLRNC BUT DID NOT DO SO IN THE PROPER FASHION. I DID NOT HAVE A PUSH TO TALK SWITCH ON MY HEADSET AND WAS UNABLE TO GIVE THE CORRECT READBACK TO THE CTLR. AFTER 3 INCORRECT READBACKS, I TOOK THE HEADSET THAT MY STUDENT HAD ON AND USED HIS PTT AND GAVE THE CORRECT READBACK. I HAD CONTROL OF COM AND NAV FOR THE BALANCE OF THE TRIP.
