I suggest you might like to ask the Instructor to show you the data on the aircraft’s windshear response that he/she has produced, which overrides that produced by the aircraft manufacturer who designed it (aided by massively powerful computers and very clever people) the aerodynamicists who wind-tunnel tested it, and the Regulatory Authorities who certified it.
He or she must be one very wise person if they are able to debunk the universal industry-standard procedure – to NOT reconfigure in windshear. Very impressive ….
