“The pilot checked the altimeter to determine the aircraft's current altitude as they soared through the sky.”

“The altimeter was counting down, the final couple of hundred feet flashing by too quickly.”

“They can still read the altimeter and airspeed, and they still have navigation aids available to them.”

“Satellite altimetry is used to identify key habitats for other marine animals, which can then be tracked and studied.”

“Satellite altimetry and ocean colour data provide additional data on spatial variability and upper ocean biology.”

“This satellite uses a technique called radar altimetry to measure the height of surfaces.”

“Apparently, the altimeters built into some Casio watches can be modified to detonate bombs at certain altitudes.”

“The Dorset-based firm produces devices such as altimeters, braking systems, smoke detectors and towed aerial targets that act as decoys for enemy fire.”

“At a height of 60 kilometres, it will be able to detect its own altitude using a pair of radar altimeters, which will be able to measure the exact distance to the surface.”
