A B737-400 First Officer advised the Missed Approach Procedure for the SEA ILS 16R does not provide an appropriate initial heading to insure crossing TECEE in order to comply with the 2;000 MSL crossing restriction. In addition; the aircraft FMS database directs a TECEE crossing at or above 2;000 MSL vice the hard 2;000 as charted.

Narrative

There are two problems with the newly published [commercial] ILS 16R SEA plate 21-3 dated 29 APR 11. One problem is with the NAV database in the jet having the wrong altitude coded for TECEE; and the other problem is that the missed approach; as written; doesn't work. We noticed that the new missed approach for Runway 16R SEA was now in the NAV database. However; the altitude for the first waypoint on the missed; TECEE; came up in the NAV database on the jet as 2;000A rather than as 2;000 FT. According to the approach plate 21-3 29 APR 11; TECEE is a hard altitude at 2;000 FT additionally; the NAV database shows a bypass above TECEE. The presumed reason is that if you follow the missed approach procedure as published; you can't get to TECEE. If; at the missed approach point (615 FT MSL you are more than 1/2 mile north of the runway threshold) you turn to the 195 heading; you will not get to the SEA 210 radial northeast of TECEE. You will intercept the SEA 210 radial southwest of TECEE (unless you have a strong west wind). So; the procedure is defective as published. Am I supposed to fly the 195 heading to intercept the SEA 210 radial to ZERLI or am I supposed to fly direct to TECEE or am I supposed to make it up and wait until I am half way down the runway (presumably in IMC; now I'm guessing where I am) and then turn to the 195 heading which will allow me to intercept the SEA 210 radial at TECEE or northeast of it? As it is written; this won't work. This missed needs to be rewritten.
