You can handle IAS problems without too much concern so long as you keep your cool and have a good knowledge of pitch and thrust settings for configuration. One of my standard exercises in endorsement training was to work the student up to the point where he/she could handle a single pilot, low vis takeoff with a pitot static failure, run the circuit and land off a low vis (the better student would be challenged with a 0/0 situation) ILS. Great for stick and rudder confidence building.
