2 aircraft flying same IAS
Simple (?) question...
If 2 aircraft (let's say an ATR 42 and an Airbus 320) are flying the same IAS (say 220KIAS) at relatively low altitudes (say 6000ft) in the same weather conditions (same temp, pressure, density, etc and assume nil wind), will they both take the same amount of time to cover 60nm?
Is the difference between the 2 aircraft's groundspeeds negligible over this distance?
