What might be of concern if a snow covered aircraft is put into a heated hangar and then taken back out into sub-freezing temperatures?
1) The snow on the aircraft may freeze and cause damage to the aircraft's structure.
2) The sudden change in temperature may cause the aircraft's systems to malfunction.
3) The snow on the aircraft may melt and cause water damage to the aircraft's interior.
4) The aircraft may become too heavy due to the accumulation of ice and snow.
