There are substitutions for the flight review which will make you a more competent pilot, learn more, and in some cases it will cost you less than a regular fight review. Before we go into that lets review what a flight review is.
1 Hydrogen bonding is the strongest type of intermolecular force arising from permanent dipole permanent dipole attraction and the partially positive proton end of one molecule attracts the partially negative nitrogen (or oxygen/fluorine) lone pair end of a close neighbouring molecule.
One of the strongest intermolecular forces (i.e. non-covalent) is the H-bond. H-bonds hold between 1 and 5 kcal/mol in free energy. Ionic bonds can also be strong, but they depend on the charge of each of the two oppositely charged molecules and the distance between them (following Coulombâs law).
