Lesson 4j - Covered Instrument Landings

Lesson Objective

The student will learn what to do if some of the flight instruments become inoperable.  If the alitmeter becomes inoperative, the student will use visual cues to determine altitude, and guide the glider to a safe landing.  If the airspeed indicator stops working, then the candidate will use reference to attitude and slipstream noise to judge airspeed. 

The student should also be able to explain the situations which could lead to each of these instruments failing.  

Regulatory Requirement


  • Landing with the altimeter covered.
  • Landing with the airspeed indicator covered.

Completion Standards

The student must be able to perform:

  • A safe landing with the altimeter covered.
  • A safe landing with the airspeed indicator covered.
