How to add/change LODs in Operational Layer (added thru MapManager.js)?

BingJing

Hi All

I added an aerial layer(see below code in MapManager), Now we want to only display aerial when zoom in to property level.  Is this achievable programmatically by applying LOD on Aerial Layer?  Or the basemap has to determine it?  I changed the basemap LODs in WebAppbuilder config but no luck.

Thank you in advance

//User Start, add aerial dynamic layer
var cAerial = new ArcGISDynamicMapServiceLayer(".....");
cAerial.isOperationalLayer = true;
map.addLayer(cAerial);
//User End
