What Can Be Done To Deal With "lo Speed"

Featured Replies

In the tutorial flight from Heathrow to Zurich the planned cruise altitude is 37,000 ft while the maximum computed in the Flight Plan is 33,500 ftIn the attachment you'll note that we're way below that level probably due to the messages reading "Lo Speed" and "Pitch"What should I do to deal with the problem please?Cliff

Cliff, try again and keep the aircraft in PROF mode and ensure the speed window is closed by pressing the FMS Speed button.....you probably entered some incorrect information in the MCDU during preflight

Cliff in the left corner of the PFD you will notice the slats are still extended, retract them and everything will be fine, you are getting a low speed warning because of the speed protection from having them extendedCheersJon

Slats are extended automatically because of the Low Speed protection

Bryan I think you have confused the low speed protection (which doesn't automatically extend the slats) with the stall warning/stick shaker activation (which does). (Edit to add) I think what has happened here is that the slats have not been retracted after takeoff and the aircraft has got to 27000ft at which point the minimum and maximum speed for the slats extended condition have converged - triggering the speed protection.

Yup..............it must have been the slats as the next flight was faultless. Thanks to all of you for your input.Cliff
