Dead reckoning begins with a known position, or rpm ) against a table of total displacement ( for ships ) or referencing one's indicated airspeed fed by the pressure from a pitot tube.
32.
From current EASA definitions : Indicated airspeed means the speed of an aircraft as shown on its pitot static airspeed indicator calibrated to reflect standard atmosphere adiabatic compressible flow at sea level uncorrected for airspeed system errors.
33.
At increased altitude ( more accurately, density altitude ), for the same given indicated airspeed ( IAS ) the aircraft's true airspeed ( TAS ) will be higher, but the same indicated airspeed limits apply.
34.

35.
:: Often when'airspeed'is referred to, what is meant is indicated airspeed ( IAS )-the speed as shown on the airspeed indicator, which only corresponds to true airspeed ( TAS ) under specific conditions.
36.
The dynamic pressure measured can be used to determine the indicated airspeed of the aircraft . The diaphragm arrangement described above is typically contained within the airspeed indicator, which converts the dynamic pressure to an airspeed reading by means of mechanical levers.
37.
By contrast, V y is the indicated airspeed for best rate of climb ., a rate which allows the aircraft to reach a specified altitude in the minimum amount of "'time "'regardless of the horizontal distance required.
38.
At higher altitudes the indicated airspeed-being measured by pitot tube instruments-was affected by differences in outside air pressure that rendered it increasingly inaccurate . ( A correct ground speed is required for accurate bombing . ) The "'Mk.
39.
This claim is disputed because it is only based on Mutke's memory of the incident, which recalls effects other Me 262 pilots observed below the speed of sound at high indicated airspeed, but with no altitude reading required to determine the actual speed.
40.
At and, the heating conditions on the shock cone would be similar to those at Sea Level and indicated airspeed, but if the speed was increased to at, the shock cone would be exposed to higher temperatures than those at Mach 1.7.
