Narrative:

I reviewed my student's preflight planning and determined that his preparation was good. I did not recognize, however, that he had planned to fly at an incorrect VFR cruising altitude. As a result, the entire cruise portion of a flight from cll to sat was conducted at 5500 ft MSL. This was plain oversight on my behalf. In fact, during our discussion during preflight planning on what altitude to fly back (at night), we discovered our error. What could have helped me realize my error? Perhaps a prompting from ATC. During the flight, I was also teaching my student how to secure VFR flight following from an ARTCC. As a result, we were in contact with center throughout the flight. I realize that is not their function, but I do know they are familiar with our cruising altitudes (I once requested the wrong altitude and was corrected by ATC).

Title: AN INSTRUCTOR PLT RPT ON NOT COMPLYING WITH THE ALT HDG RULE WHILE FLYING W FROM CLL TO SAT. THE ACFT WAS AT 5500 FT AND UNDER ARTCC RADAR OBSERVATION.

Narrative: I REVIEWED MY STUDENT'S PREFLT PLANNING AND DETERMINED THAT HIS PREPARATION WAS GOOD. I DID NOT RECOGNIZE, HOWEVER, THAT HE HAD PLANNED TO FLY AT AN INCORRECT VFR CRUISING ALT. AS A RESULT, THE ENTIRE CRUISE PORTION OF A FLT FROM CLL TO SAT WAS CONDUCTED AT 5500 FT MSL. THIS WAS PLAIN OVERSIGHT ON MY BEHALF. IN FACT, DURING OUR DISCUSSION DURING PREFLT PLANNING ON WHAT ALT TO FLY BACK (AT NIGHT), WE DISCOVERED OUR ERROR. WHAT COULD HAVE HELPED ME REALIZE MY ERROR? PERHAPS A PROMPTING FROM ATC. DURING THE FLT, I WAS ALSO TEACHING MY STUDENT HOW TO SECURE VFR FLT FOLLOWING FROM AN ARTCC. AS A RESULT, WE WERE IN CONTACT WITH CTR THROUGHOUT THE FLT. I REALIZE THAT IS NOT THEIR FUNCTION, BUT I DO KNOW THEY ARE FAMILIAR WITH OUR CRUISING ALTS (I ONCE REQUESTED THE WRONG ALT AND WAS CORRECTED BY ATC).
