With out doubt the Sandel EHSI is a clever bit of kit doing all and more than Capt manuvar says but it has two big problems , First is that you can't see it from the right hand seat and it's performance in bright sunlight is poor. Second it has a 200 hour life bulb and sods law states that it will fail on a dirty night when the WX is overcast at 300 with 600M RVR.
Sandel are adressing these problems with a new display that is based on a Biz jet VSI the unit will have all the features of the presant unit but the projection system will have a 2000 hour life from the light sorce and will work in bright sunlight and be visable frm the RH seat.
Sandel expect to be shipping these units in April 2005.
